plztell.me vs cheat.sh vs tldr: Which Command Line Help Tool is Right for You?

Ali — Mon, 09 Feb 2026 00:00:00 +0000

You're in a terminal. You forgot a command flag. Do you type man and scroll through dense documentation? Google and lose your flow? Or do you use one of the terminal help tools everyone's talking about — cheat.sh , tldr , or plztell.me?

These three tools solve the same core problem: getting command line help without leaving your terminal. But they take fundamentally different approaches. Let's break down which one fits your workflow.

The Problem: Man Pages Are Too Dense, Google Breaks Your Flow

Man pages were designed in the 1970s. They're comprehensive, but they're not fast. When you just need to remember how to extract a tar.gz file or find files modified in the last 24 hours, you don't want to read six pages of documentation.

Googling is faster — but it means context-switching to a browser, scanning Stack Overflow, and copy-pasting commands you half-understand. If you're SSH'd into a server, you might not even have a browser available.

This is why tools like cheat.sh, tldr, and plztell.me exist. They bring help directly into your terminal. But they're very different tools.

Quick Overview: What Each Tool Does

cheat.sh — The Comprehensive Cheatsheet Library

cheat.sh is a massive community-maintained collection of cheatsheets covering 56+ programming languages, command-line tools, and UNIX utilities. You query it via curl cht.sh/command, and it returns static examples curated by contributors.

Best for: Looking up syntax for programming languages (Python, Go, JavaScript) or getting comprehensive command examples (tar, rsync, ffmpeg).

tldr — Simplified Man Pages

tldr (stands for "too long; didn't read") is a crowdsourced collection of simplified, practical command examples. It's a man page alternative focused on the most common use cases. You install a client (npm install -g tldr or brew install tldr) and run tldr command.

Best for: Quick syntax reminders when you just need a working example of a common command (cp, grep, find, chmod).

plztell.me — AI-Powered Terminal Assistant

plztell.me isn't a cheatsheet lookup tool — it's an AI assistant that lives in your terminal. You can ask it anything in natural language, pipe in command output or log files for analysis, and have an interactive conversation. No installation, no signup, no API key required.

Best for: Interactive debugging, analyzing piped input (logs, errors, configs), asking follow-up questions, and getting explanations tailored to your exact situation.

Side-by-Side Comparison

Feature	plztell.me	cheat.sh	tldr
Type	AI assistant (conversational)	Static cheatsheet lookup	Static example lookup

Best Use Case	Debugging, log analysis, interactive help	Programming language reference + complex CLI tools	Quick syntax reminders for common commands

The Key Differences

1. Static Lookup vs AI Conversation

cheat.sh and tldr are lookup tools — you query a command, and you get back pre-written examples. They're fast, reliable, and work offline (with caching).

plztell.me is conversational AI — you can ask questions in natural language, get tailored explanations, and ask follow-up questions. It's not looking up static content; it's generating answers on the fly based on your exact query.

2. Read-Only vs Context-Aware

cheat.sh and tldr can only show you examples. They can't read your logs, analyze your errors, or understand your specific environment.

plztell.me accepts piped input — pipe in a log file, an error message, or a config file, and the AI will analyze it and give you context-specific advice. Example:

tail -100 /var/log/nginx/error.log | plz "why am i getting 502 errors?"

This is something cheat.sh and tldr simply can't do — they have no concept of your context.

3. Command Coverage

tldr focuses on ~1,000 of the most commonly used commands. It's intentionally minimal.

cheat.sh is comprehensive, covering 56+ programming languages and thousands of tools — everything from Python standard library functions to obscure CLI utilities.

plztell.me has unlimited coverage — if the AI knows about it (and it knows about virtually every command-line tool and programming language), you can ask about it. No manual curation needed.

4. Offline Availability

Both cheat.sh and tldr support offline mode with local caching. Once you've queried a command, the cheatsheet is cached locally.

plztell.me requires an internet connection — it's powered by real-time AI inference, not static files.

When to Use tldr

Choose tldr if:

You just need a quick syntax reminder — "How do I use tar again?" tldr gives you the 3 most common examples, nothing more.
You want offline access — tldr downloads pages locally, so you can look up commands without internet.
You prefer minimalism — tldr strips away the noise. Each page is a handful of practical examples.
You already know the command name — tldr doesn't do natural language queries. You must know you're looking for rsync, not "how to sync files between servers."

When to Use cheat.sh

Choose cheat.sh if:

You need programming language references — cheat.sh has cheatsheets for Python, Go, JavaScript, Ruby, Rust, and 50+ more languages. Example: curl cht.sh/python/list+comprehension
You want comprehensive examples — cheat.sh pages often include multiple use cases, flags, and edge cases — more detailed than tldr.
You like community-driven content — cheat.sh aggregates cheatsheets from multiple sources, including community contributions.
You need offline support — Like tldr, cheat.sh supports caching for offline use.

When to Use plztell.me

Choose plztell.me if:

You need to analyze piped input — Debugging a failed script? Analyzing log files? Trying to understand a cryptic error message? Pipe it into plz and get AI-powered analysis.
You want interactive help — Ask a question, get an answer, then ask follow-up questions. plztell.me maintains conversation context.
You don't know the exact command name — Instead of knowing you need rsync, just ask: plz how do I sync files between two servers
You want explanations, not just examples — plztell.me doesn't just give you a command — it explains what it does, why it works, and when to use it.
You need help with complex, multi-step tasks — "How do I set up a reverse proxy with nginx for a Node.js app?" plztell.me can walk you through the entire process.
You want zero setup — No installation, no account, no API key. Just curl plztell.me/setup and you're ready.

Real-World Examples: Same Question, Three Tools

Example 1: "How do I find large files?"

tldr approach:

tldr find

Result: Generic find examples. You have to know to look for -size flag and piece together the command yourself.

cheat.sh approach:

curl cht.sh/find

Result: Comprehensive cheatsheet with dozens of examples. You scroll until you find the size-based search example.

plztell.me approach:

plz how do i find files larger than 1GB

Result: Direct answer with the exact command, plus an explanation of what each flag does. If you ask "what if I want to delete them automatically?", it gives you a follow-up command with safety warnings.

Example 2: Debugging a Failed Command

You ran a command and got an error:

rsync -avz /source/ user@host:/dest/

Error: rsync: connection unexpectedly closed (0 bytes received so far) [sender]

tldr and cheat.sh:

Both tools show you rsync syntax examples, but they can't read your error message or diagnose the problem. You're back to Googling the error.

plztell.me:

plz rsync error: connection unexpectedly closed

Result: The AI explains common causes (SSH key issues, firewall blocking port 22, wrong path, rsync not installed on remote) and gives you diagnostic commands to narrow down the problem.

Can You Use All Three Together?

Absolutely. These tools aren't mutually exclusive.

Use tldr when you just need a quick syntax reminder and you know the command name.
Use cheat.sh when you're writing code in a specific language and need a reference for standard library functions or language syntax.
Use plztell.me when you're debugging, analyzing logs, need an explanation, or want to ask questions in natural language.

Think of tldr and cheat.sh as reference books, and plztell.me as a knowledgeable colleague who's always available to answer questions and help you troubleshoot.

Try plztell.me in 10 Seconds

No signup. No API key. No installation. Just copy and paste:

Linux / macOS

eval "$(curl -sL plztell.me/setup)"

eval "$(wget -qO- plztell.me/setup)"

Windows

iex (iwr -useb plztell.me/setup/win).Content

Then ask anything:

plz how do i monitor disk usage in real-time

Or pipe in context for analysis:

docker logs my-container | plz "why is this container crashing?"

Tip: Use quotes if your question contains shell special characters like ? ! & | ; ' " $ * < > etc.

That's it — you're using Gemini 2.0 Flash for free, no account needed.

The Bottom Line

All three tools exist to save you from dense man pages and context-switching to Google — but they serve different needs:

tldr — Best for quick syntax lookups when you know the command. Minimal, fast, works offline.
cheat.sh — Best for comprehensive references including programming languages. Community-driven, works offline.
plztell.me — Best for interactive debugging, log analysis, natural language queries, and getting explanations tailored to your exact situation. AI-powered, conversational, context-aware.

You don't have to choose just one — use tldr for quick lookups, cheat.sh for language references, and plztell.me when you need real help solving a problem.

Try plztell.me — it takes 5 seconds and costs nothing. See what AI-powered terminal assistance feels like compared to static cheatsheets.

Man Pages Are Unreadable — Here's a Better Way to Learn Commands

Ali — Sat, 07 Feb 2026 00:00:00 +0000

You need to copy files between servers. You type man rsync. The man page is 4,500 lines long.

Twenty minutes later, you still don't know whether you need -a or -r, so you close it and Google "rsync copy directory to remote server" instead. Man pages are the oldest documentation system in Unix — and for most people, they're effectively unusable.

Why Man Pages Don't Work

Man pages document everything — every flag, every edge case — in a format designed for reference, not learning:

Too long — find is 1,000+ lines. rsync is 4,500+. git has a separate novel for every subcommand.
Assume prior knowledge — "Canonicalize existing paths" isn't helpful when you just want to copy a directory.
No practical examples — Flags and descriptions, but rarely how to combine them for common tasks.
You can't ask questions — Static text. You can't say "which flags preserve permissions?" — you read the whole thing and figure it out.

The result? Most people skip man pages and go straight to Google.

The Current Alternatives (And Their Limits)

Tools like tldr pages and cheat.sh help — but they pull from static databases. If your question is slightly unusual, you won't find it. And Google/Stack Overflow require leaving your terminal, which isn't always possible on a headless server.

They all give pre-written answers to pre-anticipated questions. If your question hasn't been asked before, you're out of luck.

Ask Any Question. Get a Real Answer.

With plztell.me , you don't search through documentation — you just ask your question in plain English, right in your terminal:

plz explain the rsync command with common examples

plz what does tar -xzvf mean flag by flag

plz how do I use find to search for files larger than 100MB

You get a concise, practical answer — not 4,500 lines of reference material. Just the information you need, in language that actually makes sense.

Understand Flags Without Reading the Whole Man Page

Most of the time, you don't need to understand an entire command — you need to understand one or two specific flags. Man pages make you hunt for a needle in a haystack. With plztell.me, just ask about the specific flag:

plz what does the -a flag do in rsync

plz difference between chmod 755 and chmod 644

plz what ssh options do I need to tunnel port 3306

Direct answers about exactly what you asked. Follow up if you need more — context is preserved within your session.

The Commands Everyone Struggles With

Some man pages are famously impenetrable. Instead of scrolling, just ask:

plz show me the most useful find command examples

plz how does awk work with simple examples

plz iptables basics for allowing SSH and blocking everything else

Answers in seconds — not minutes of scrolling through thousands of lines.

Set Up in 5 Seconds

No signup. No API key. No installation. Just copy and paste:

Linux / macOS

eval "$(curl -sL plztell.me/setup)"

eval "$(wget -qO- plztell.me/setup)"

Windows

iex (iwr -useb plztell.me/setup/win).Content

Then ask about any command:

plz explain the rsync command with common examples

Tip: Use quotes if your question contains shell special characters like ? ! & | ; ' " $ * < > etc.

Man Pages Had Their Time. This Is Better.

Man pages are the definitive reference — but that's not what you need when you just want to copy a directory to a remote server. You need a concise answer in plain English, right in your terminal.

Try plztell.me — set it up in 5 seconds and never suffer through a man page again.

Stop Searching for Cheatsheets — Generate Them Instantly in Your Terminal

Ali — Sat, 07 Feb 2026 00:00:00 +0000

Be honest — how many times this week have you Googled "git cheatsheet" or "docker commands cheatsheet"?

You search, scroll past ads, find a PDF, scan it for the one command you need, and bookmark it "for later." Next week, you can't find the bookmark — or the cheatsheet doesn't cover your use case. So you do it all over again.

The Cheatsheets Everyone Keeps Googling

If you work in infrastructure, you know these searches by heart:

"git cheatsheet" — Rebasing, cherry-picking, stashing. You use git daily, but some commands never stick.
"docker cheatsheet" — Container lifecycle, volumes, networking. The CLI is massive.
"tcpdump cheatsheet" — You only need it when something is broken, so the flags never feel familiar.
"kubernetes cheatsheet" — kubectl get, describe, logs, exec, port-forward. The surface area is enormous.
"iptables cheatsheet" — Chains, rules, NAT, port forwarding. One wrong rule and you lock yourself out.

The pattern is always the same: search, scan, copy, forget, repeat.

The Problem with Stored Cheatsheets

You've tried to solve this — bookmarked pages, saved PDFs, pinned GitHub repos, built a Notion wiki. None of it sticks.

Static cheatsheets are a dead end. They go stale, they're generic, and they never cover your exact situation. And the moment you need one, you're context-switching out of your terminal — the last thing you want at 2 AM debugging a production issue.

Stop Searching. Start Generating.

What if you could generate a cheatsheet for any tool, on demand, right in your terminal — exactly when and where you need it?

That's exactly what plztell.me does. Set it up in 5 seconds, then just ask:

plz docker cheatsheet

plz git cheatsheet

plz tcpdump cheatsheet

The AI generates a concise, practical cheatsheet right in your terminal. No browser, no bookmarks, no PDFs.

Go Beyond Generic Cheatsheets

Static cheatsheets give you everything — which means you're scanning for the one thing you care about. With plztell.me, ask for exactly what you need:

plz git cheatsheet for branching and merging

plz kubectl cheatsheet for debugging crashed pods

A tailored reference — not a 10-page PDF where 90% doesn't apply.

Set Up in 5 Seconds

No signup. No API key. No installation. Just copy and paste:

Linux / macOS

eval "$(curl -sL plztell.me/setup)"

eval "$(wget -qO- plztell.me/setup)"

Windows

iex (iwr -useb plztell.me/setup/win).Content

Then start generating cheatsheets:

plz docker cheatsheet

Tip: Use quotes if your question contains shell special characters like ? ! & | ; ' " $ * < > etc.

That's it — you're using Gemini 2.0 Flash for free, no account needed. Your personal cheatsheet generator, available in every terminal session.

Your Cheatsheets Should Work for You

You need the right commands, in the right place, at the right time. That place is your terminal.

Try plztell.me — set it up in 5 seconds, then type plz docker cheatsheet and see for yourself.

Stop Googling Cron Syntax — Generate Cron Expressions in Your Terminal

Ali — Sat, 07 Feb 2026 00:00:00 +0000

Quick — what's the cron expression for "every weekday at 3:15 AM"? If you just opened a browser tab to look it up, you're not alone. No matter how many times you've written a cron job, the syntax never sticks.

Why Cron Syntax Never Sticks

Cron's five-field format looks simple on paper:

┌───── minute (0-59)
│ ┌───── hour (0-23)
│ │ ┌───── day of month (1-31)
│ │ │ ┌───── month (1-12)
│ │ │ │ ┌───── day of week (0-7)
│ │ │ │ │
* * * * *

But beyond the basics, it gets confusing fast:

What's the difference between */5 and 5?
Is Sunday 0 or 7? (Both, actually.)
How do you combine day-of-month and day-of-week without conflicts?

Throw in extended syntax with @yearly, @reboot, or six-field formats, and even experienced sysadmins reach for Google.

The Crontab Google Cycle

You know the pattern: open browser, search "cron expression every 15 minutes," land on crontab.guru, copy the expression, paste it in. Two weeks later, repeat.

It works, but it's slow and breaks your flow. And on a headless server with no browser, you're stuck with the crontab man page.

Just Ask in Plain English

With plztell.me , you skip the browser entirely. Just describe what you want in natural language:

plz crontab for every weekday at 3am

plz cron expression to run every 15 minutes

plz cron job for the 1st and 15th of every month at midnight

You get the exact cron expression, right in your terminal, in seconds. No browser tab, no context-switching, no deciphering Stack Overflow answers.

Explain Cron Expressions You Inherited

Half the time, you're not writing a new cron job — you're staring at one someone else wrote and trying to figure out what it does. The expression 0 */6 * * 1-5 in a crontab you inherited from a colleague who left the company doesn't come with documentation.

Just ask:

plz "explain this cron expression: 0 */6 * * 1-5"

plz "what does this cron mean: 30 4 1-7 * 1"

You get a plain-English breakdown — no mental gymnastics required. And if you want to modify it, just follow up:

plz change that to run on weekends instead

Context is preserved, so the AI knows exactly which expression you're referring to.

Real-World Cron Jobs, Generated Instantly

The expressions people Google every day — just ask instead:

plz cron to rotate logs every Sunday at 2am

plz crontab to backup database every 6 hours

plz cron to run a health check every 5 minutes during business hours

Stay in your terminal and keep working.

Set Up in 5 Seconds

No signup. No API key. No installation. Just copy and paste:

Linux / macOS

eval "$(curl -sL plztell.me/setup)"

eval "$(wget -qO- plztell.me/setup)"

Windows

iex (iwr -useb plztell.me/setup/win).Content

Then never Google cron syntax again:

plz crontab for every weekday at 3am

Tip: Use quotes if your question contains shell special characters like ? ! & | ; ' " $ * < > etc.

That's it — you're using Gemini 2.0 Flash for free, no account needed. Your personal cron translator, available in every terminal session.

Cron Syntax Is a Solved Problem

You shouldn't need to memorize a five-field format you use a few times a month. Just describe what you want. Get the answer. Stay in your terminal.

Try plztell.me — set it up in 5 seconds and never Google cron syntax again.

You Don't Need to Memorize Regex — Just Ask Your Terminal

Ali — Sat, 07 Feb 2026 00:00:00 +0000

There's a famous joke: "You have a problem. You decide to solve it with regex. Now you have two problems."

Everyone uses regular expressions. Nobody enjoys writing them. So we Google it, copy from Stack Overflow, paste it in and pray. Six months later, we look at it and have no idea what it does.

The Regex Searches Everyone Makes

If you've worked with text processing or log parsing, you've Googled these:

"regex for email address" — Looks simple, turns into a 200-character monster if you want RFC compliance.
"regex for IP address" — IPv4 seems easy until \d{1,3} matches 999. IPv6 is worse.
"regex to match URL" — Protocols, subdomains, ports, paths, query strings. Good luck.
"regex for date format" — YYYY-MM-DD? MM/DD/YYYY? Each one is a different pattern.

Every one sends you through a maze of Stack Overflow answers (half outdated), and back to your terminal hoping the pattern works.

Regex Is a Write-Only Language

Try to figure out what this does in 10 seconds:

^(?:(?:25[0-5]|2[0-4]\d|[01]?\d\d?)\.){3}(?:25[0-5]|2[0-4]\d|[01]?\d\d?)$

That's an IPv4 validator. Correct, well-written — and completely unreadable. The gap between "what you want to match" and "the pattern that matches it" is enormous. You think in English. Regex speaks in hieroglyphics.

Describe What You Want. Get the Regex.

With plztell.me , you bridge that gap instantly. Describe what you want to match in plain English, and get a working regex pattern right in your terminal:

plz regex to match email addresses

plz regex for valid IPv4 addresses

plz regex to match dates in YYYY-MM-DD format

No memorization. No cheatsheets. No Stack Overflow rabbit holes. Just the pattern you need, when you need it.

Decode Regex You Didn't Write

Maybe the bigger pain point isn't writing regex — it's reading it. You open a script, a config file, or a log parser, and there's a regex pattern staring at you like ancient runes. You have no idea what it matches, and the person who wrote it didn't leave a comment.

Just paste it in and ask:

plz "explain this regex: ^(?:(?:25[0-5]|2[0-4]\d|[01]?\d\d?)\.){3}(?:25[0-5]|2[0-4]\d|[01]?\d\d?)$"

The AI breaks it down piece by piece in plain English. Then you can follow up:

plz modify that to also match IPv6 addresses

Context is preserved, so the AI knows which pattern you're talking about. No starting over.

Get Regex for the Exact Tool You're Using

Regex syntax varies between tools. What works in Python might not work in grep. What works in grep might need escaping in sed. Instead of guessing, just ask for the specific tool:

plz grep regex to find lines with IP addresses in a log file

plz sed command to replace dates from MM/DD/YYYY to YYYY-MM-DD

plz python regex to validate phone numbers with country code

You get the complete command ready to run — not just the raw pattern. No escaping headaches.

Set Up in 5 Seconds

No signup. No API key. No installation. Just copy and paste:

Linux / macOS

eval "$(curl -sL plztell.me/setup)"

eval "$(wget -qO- plztell.me/setup)"

Windows

iex (iwr -useb plztell.me/setup/win).Content

Then generate any regex pattern you need:

plz regex to match email addresses

Tip: Use quotes if your question contains shell special characters like ? ! & | ; ' " $ * < > etc.

That's it — you're using Gemini 2.0 Flash for free, no account needed. Your personal regex generator, right in your terminal.

Regex Should Be a Tool, Not a Puzzle

You don't need to memorize every metacharacter and lookahead. Just describe what you want to match and let the AI handle the syntax.

Try plztell.me — set it up in 5 seconds, then type plz regex to match email addresses and stop wrestling with regex forever.

plztell.me vs Shell-GPT vs Mods: Terminal AI Tools Compared

Ali — Fri, 06 Feb 2026 00:00:00 +0000

You're SSH'd into a production server. Something breaks. You need answers fast, but you can't open a browser. This is where terminal AI assistants shine — Shell-GPT , Mods by Charmbracelet, and plztell.me.

Which one should you use? It depends on your environment and how much setup you're willing to do.

The Problem All Three Tools Solve

AI chatbots are great for debugging and writing scripts — but they live in a browser. The copy-paste dance between terminal and browser kills your flow, especially on remote servers.

Terminal AI assistants eliminate this context-switching. Shell-GPT (sgpt), Mods by Charmbracelet, and plztell.me all solve this — but they take very different approaches.

Side-by-Side Comparison

Feature	plztell.me	Shell-GPT	Mods
Installation	None — just curl/wget	Requires `pip install shell-gpt`	Requires `brew install`, apt, or Go binary
Time to First Query	~5 seconds	Minutes (install + API key setup)	Minutes (install + API key or local model setup)
API Key Required	No — handled for you	Yes — your own OpenAI API key	Yes — OpenAI, Cohere, Groq, or local model
Signup Required	No — free tier works instantly	Yes — OpenAI account required	Yes — provider account or local model setup
Configuration	Zero — works out of the box	Config file + API key env variable	Config file + API key env variable(s)
Dependencies	Only curl or wget (pre-installed everywhere)	Python 3.x + pip	Single Go binary (no runtime deps)
Works on Restricted Servers	Yes — the only tool that does	No — requires package installation	No — requires binary installation
AI Model (Free)	Gemini 2.0 Flash — no cost at all	N/A (requires paid API key)	Free with local models via LocalAI
Billing Surprises	None — pay-as-you-go, credits never expire	Possible — usage-based OpenAI billing	Possible — depends on provider billing
Privacy	Queries never stored; not used for training	Depends on OpenAI's policies	Depends on chosen provider (local = full privacy)
Pricing	Free forever (no signup) + optional pay-as-you-go (~1-5¢/query)	Free tool, but requires paid API key	Free & open source (MIT), but requires API key or local model

The Key Difference

Shell-GPT and Mods are powerful tools — but they both require you to install software, obtain API keys, and configure settings before you can ask your first question. plztell.me is the only tool that works instantly, everywhere, with zero setup. If curl or wget exists on the machine — and it does on virtually every Linux, macOS, and Windows system — you're ready to go.

When to Use plztell.me

Choose plztell.me if:

You can't install software — Locked-down server? No pip, no Go binary needed. If curl or wget exists, you have AI.
You don't want to manage API keys — No OpenAI signup, no config files, no billing surprises. The AI is handled server-side.
You need answers now — One command loads the plz function. You're asking questions in under 5 seconds.
You want predictable costs — Free tier with unlimited questions. Paid tier is ~1-5¢ per query with credits that never expire.

When to Use Shell-GPT

Choose Shell-GPT if:

You want deep shell integration — Hotkey support (Ctrl+L) puts AI completions directly into your terminal buffer, and it can execute generated commands directly.
You need function calling — Shell-GPT can execute custom functions autonomously based on AI decisions — powerful for automation.
You already have an OpenAI API key — If you're paying for GPT-4 access, Shell-GPT lets you use it from the terminal with REPL mode for interactive chat.

When to Use Mods

Choose Mods if:

You want multi-provider flexibility — Supports OpenAI, Cohere, Groq, Gemini, Azure OpenAI, and local models via LocalAI.
You build Unix pipelines — Designed for pipeline workflows. Pipe command output in, get formatted Markdown, JSON, or plain text out.
You want to run models locally — With LocalAI integration, Mods works entirely offline. No data leaves your machine.

Try plztell.me in 10 Seconds

No signup. No API key. No installation. Just copy and paste:

Linux / macOS

eval "$(curl -sL plztell.me/setup)"

eval "$(wget -qO- plztell.me/setup)"

Windows

iex (iwr -useb plztell.me/setup/win).Content

Then ask anything:

plz how do i find files larger than 1GB

Or pipe in context for analysis:

cat /var/log/nginx/error.log | plz "why am i getting 502 errors?"

Tip: Use quotes if your question contains shell special characters like ? ! & | ; ' " $ * < > etc.

That's it — you're using Gemini 2.0 Flash for free, no account needed. When you're ready for more:

Sign up — still free

Create a free account to unlock conversation history and session management across terminals. Takes seconds via plz login.

The Bottom Line

Most people just need a quick AI answer in their terminal — not multi-provider support or YAML config files. That's where plztell.me stands apart:

plztell.me — Zero installation, zero config, zero API keys. Works everywhere curl exists. Free, no signup.
Shell-GPT — Best for deep shell integration and function calling. Requires Python + OpenAI API key.
Mods — Best for pipeline workflows and local models. Requires installation + API key.

Try plztell.me — it takes 5 seconds and costs nothing. If you later need shell hotkeys or pipeline-native JSON, Shell-GPT and Mods will be there.
