Show HN: Oh My Senior – AI-powered codebase analysis

Hi HN,

I created this toy project after seeing developers on HN and Reddit leveraging Gemini's large context window to analyze entire codebases. Inspired by their insights, I wanted to streamline this process.

While I've seen similar attempts, most tools like the @codebase feature in Continue VSCode extension are editor-bound or CLI-based.

I wanted a simple web-based tool that integrates with my GitHub account directly.

This tool uses Gemini's API to analyze codebases, providing insights and answering questions about the code.

It's particularly useful for:

- Developers who've inherited projects without documentation or knowledgeable colleagues

- New engineers during onboarding

- Getting a fresh perspective on complex codebases

Key features:

- Web-based interface for easy use

- Supports multi-turn conversations

- Markdown formatting in responses

Currently using Gemini API (free quota available), but plan to add support for other models with free quotas like Codestral.

This is a PoC with basic functionality. I've tested it on several of my own repositories with promising results. Feedback and suggestions welcome!

Disclaimer: The quality of responses is inherently limited by Gemini's capabilities. This tool streamlines the process but cannot exceed Gemini's underlying performance.
