I used to be skeptical about AI browser extensions. Most felt like gimmicky solutions looking for problems, cluttering my browser with notifications and half-baked features that promised the world but delivered maybe a decent autocomplete.
That changed when I started working with tighter deadlines and realized I was spending way too much time on repetitive tasks—writing the same types of emails, researching APIs, and jumping between documentation. I decided to give AI extensions another shot, but this time I was ruthless about which ones actually earned their place in my workflow.
After testing dozens of extensions over the past six months, I've found seven that genuinely save me time every day. Here's what's actually worth installing, and more importantly, what each one does best.
Grammarly - Beyond Basic Grammar Checking
Grammarly isn't new, but its AI improvements over the past year have made it indispensable for developer communication. While the basic grammar checking is solid, the real value comes from tone adjustment and clarity suggestions.
I use it constantly when writing technical documentation or explaining complex concepts to non-technical stakeholders. The extension catches when I'm being too verbose or when my explanations might confuse someone who doesn't live in code all day.
What works well: The tone detector helps me catch when I sound frustrated in code review comments or overly technical in client emails. The clarity suggestions often help me cut unnecessary words from documentation.
Skip the premium version unless you're writing a lot of long-form content. The free tier handles most developer communication needs perfectly.
Notion AI - Context-Aware Note Organization
If you're already using Notion for project management or documentation, the AI extension transforms how you capture and organize information while browsing.
I use it most when researching new libraries or frameworks. Instead of copying links and hoping I'll remember why they mattered, I can highlight text and ask Notion AI to summarize it with context about why it's relevant to my current project.
Real workflow example: When evaluating a new database solution, I highlight key performance benchmarks from different articles. Notion AI creates organized comparison notes automatically, saving me from manually formatting tables later.
The extension works best when you give it specific context about what you're working on. Generic "summarize this" requests aren't particularly useful.
ChatGPT for Chrome - Quick Code Explanations
This unofficial extension puts ChatGPT in your browser sidebar, which sounds simple but proves incredibly useful for developers who encounter unfamiliar code patterns throughout the day.
I find myself using it most when reviewing pull requests or working with legacy codebases. Instead of spending 10 minutes tracing through unfamiliar functions, I can paste a code snippet and get a quick explanation of what it does and potential issues to watch for.
Important caveat: Never paste proprietary code. I only use this for open-source examples or code patterns I'm trying to understand conceptually. For anything work-related, stick to general questions about syntax or best practices.
Monica - AI Assistant for Research Tasks
Monica feels like having a research assistant that actually understands developer workflows. Unlike general-purpose AI assistants, it excels at technical research and can access current information about libraries, frameworks, and tools.
Where it shines is helping compare different solutions. When I need to choose between competing libraries, Monica can pull recent discussions, performance comparisons, and community sentiment without me having to manually search through Reddit threads and GitHub issues.
Best use case: Before starting new projects, I ask Monica to research the current state of specific technology stacks. It saves hours of manual research and often surfaces discussions I wouldn't have found otherwise.
The free tier gives you enough queries for casual use, but heavy researchers will probably want the upgrade.
Scribe - Automatic Process Documentation
Scribe automatically creates step-by-step documentation as you work through processes in your browser. For developers who need to document deployment procedures, testing workflows, or onboarding processes, it's genuinely magical.
I started using it when I realized I was spending entire afternoons writing deployment guides that would be outdated within a month. Now I just run through the process once with Scribe recording, then edit the generated documentation.
Pro tip: Use it for creating internal wikis about third-party tools your team uses. When someone asks "how do I set up monitoring for this service again," you have visual, step-by-step guides instead of trying to remember from memory.
The AI editing suggestions help clean up the generated documentation, making it readable rather than just a series of screenshots.
Compose AI - Smart Email and Slack Responses
Compose AI handles the repetitive parts of developer communication—status updates, meeting scheduling, and the dozens of small responses that eat up time throughout the day.
What sets it apart is that it learns your writing style and common responses. After a few weeks, it suggests responses that actually sound like something I'd write, not generic corporate speak.
Where it excels: Turning quick notes into professional emails. I can type "meeting went well, next steps are testing the API integration and updating docs" and get a properly formatted project update email.
I also use it for standardizing code review feedback. Instead of rewriting the same explanations about why certain patterns are problematic, I can generate consistent, helpful feedback quickly.
Summarize - Research Without the Overwhelm
Summarize does one thing exceptionally well: it creates useful summaries of technical articles, documentation, and research papers. Unlike general summarization tools, it preserves technical details that matter to developers.
I use it most when keeping up with industry trends or researching solutions to specific problems. Instead of bookmarking articles I'll never have time to re-read fully, I get focused summaries that capture the key insights.
Practical workflow: When researching performance optimization techniques, I run 5-6 relevant articles through Summarize, then compile the key points into a single reference document. It turns hours of reading into 20 minutes of focused research.
The extension works directly on the page, so there's no copying and pasting content into separate tools.
Making AI Extensions Actually Useful
The key to getting value from these extensions is being selective about what you automate and maintaining clear boundaries around sensitive information.
I've found the biggest productivity gains come from automating the small, repetitive tasks rather than trying to replace complex decision-making. Use AI to handle the routine communication, research, and documentation tasks, but keep the strategic and creative work for yourself.
Most importantly, don't install everything at once. Start with one or two extensions that address your biggest time-wasters, get comfortable with them, then gradually add others if they solve real problems.
What AI browser extensions have you found genuinely useful in your development workflow? I'm always curious to hear about tools that solve real problems rather than creating new ones.
