I Built an AI Documentation Generator

The Story:

Got laid off earlier this year. Instead of just sending out applications, I decided to build something I wish existed: an AI tool that automatically generates documentation from code.

What It Does:

Connects to your GitHub repos and creates comprehensive documentation using GPT-4 and tree-sitter code parsing.

Features:

• Supports 6 languages: Python, JavaScript, Java, Ruby, Go, C++
• Generates API docs, function/class references, and technical guides
• GitHub OAuth integration
• Analyzes code structure intelligently

Try it: https://docs-generator-two.vercel.app

Tech Stack

• Backend: FastAPI (Python)
• Frontend: React + TypeScript + Vite
• Database: PostgreSQL
• AI: OpenAI GPT-4
• Hosting: Railway + Vercel
• Auth: GitHub OAuth

Why I Built This

Documentation is tedious. Every developer I know (including myself) hates writing docs but knows they're critical. I wanted to see if AI could actually do this well.

What I'm Looking For

I need 5 honest beta testers before I productize this.

Questions I need answered:

• Does this actually solve a problem?
• What's missing?
• Would you pay for this?
• What features would make it genuinely useful?

The Build Journey

Built in about a month. Some interesting technical challenges:

• Getting tree-sitter working with all 6 languages (dependency hell)
• Designing prompts that generate useful docs (not just code summaries)
• Handling large repos without timeout issues
