Stop Building Basic Bots: How I Built 4 "Production-Ready" AI Agents in n8n (Vision, Memory, & Reporting)

We all love building workflows in n8n. But let’s be honest: there is a huge gap between a simple "Hello World" chatbot and a robust, production-ready AI Agent that can handle real-world complexity.

I spent the last few weeks pushing n8n to its limits to solve four specific headaches I faced in automation: Memory, Dynamic Scraping, Content Analysis, and Reporting.

Here is a breakdown of the 4 advanced agents I built, the tech stack I used, and how they solve problems standard workflows can't.

1. The "Amnesia" Problem (Long-Term Memory Agent) The Problem: Most LLM chains in n8n forget the user's context as soon as the execution ends. The Solution: I built an agent that mimics human memory.

How it works: Instead of relying solely on window memory, this workflow connects to Google Docs.

The Logic: The AI analyzes the user's input. If it detects personal details or preferences, it "saves" them to a specific doc (Long-Term Memory). If it detects a request, it saves it as a "Note."

Result: A bot that actually remembers who you are weeks later.

1. The "Vision" Scraper (Scraping Without Selectors) The Problem: Traditional scraping relies on CSS selectors. If the website updates its UI, your scraper breaks. The Solution: An agent that "sees" instead of reading code.

The Stack: ScrapingBee (for rendering) + Google Gemini Vision.

How it works: The workflow takes a screenshot of the webpage. Then, it passes that image to Gemini 1.5 Pro with a prompt to extract structured JSON data (Prices, Titles, etc.).

Why it helps: It’s virtually unbreakable because it doesn't care about div or class names.

1. The YouTube Analyst The Problem: I needed to extract insights from technical videos without watching them for 40 minutes. The Solution: An automated Summarizer & Analyst.

Flow: YouTube API (Get URL) -> Extract Transcript -> OpenAI (Analyze) -> Telegram.

Key Feature: It doesn't just summarize; it breaks down definitions, characteristics, and actionable steps into a structured report delivered to chat.

1. The Auto-Reporter The Problem: Manually updating spreadsheets with community stats (GitHub, etc.) is tedious. The Solution: A fully automated reporting agent.

Flow: Scrapes Data -> Aggregates Stats -> Generates Markdown Report -> Saves to Drive/Emails stakeholders.

Why I Bundled These?
Building these from scratch involved a lot of trial and error, specifically figuring out the prompt engineering for the Vision model and the logic routing for the Memory agent.

If you want to build these yourself, I highly recommend exploring Gemini's Vision capabilities in n8n—it's a game changer for scraping.

However, if you want to skip the debugging phase...

I’ve packaged all 4 of these workflows into a "Mastery Pack." They are cleaned up, annotated, and ready to import.

💡 Think about it: A developer's hour is valuable. You can build this yourself, or you can save 10+ hours of development time and grab the JSON files instantly.
