Every repo deserves
a second read.

Paste a GitHub repo and an AI agent reads the file tree, decides what actually matters, and gives you an architecture diagram, a plain-English summary, and a chat interface — so you're never staring at an unfamiliar codebase cold.

See it in action.

This is the actual analysis Second Read generated for a real repo — iampriyabrat14/crewai-multiagent-supportops, a multi-agent CrewAI support system.

Summary

A production-grade customer support system that uses multiple AI agents to triage and resolve support cases — combining NLP, knowledge retrieval, and custom tools to understand issues, retrieve context, and act. An episodic memory component lets it learn from past resolved cases.

Tech stack

  • CrewAI for multi-agent orchestration
  • Pinecone for vector search / retrieval
  • FastAPI + Pydantic for the API layer
  • MCP for custom tool integration

Architecture


      

Three steps. Zero setup.

01
🔎

Fetch & triage

Reads the repo's file tree via the GitHub API and reasons about which files actually matter — entry points, config, core modules.

02
🧠

Understand & map

Generates a plain-English summary and an architecture diagram showing how the pieces connect.

03
💬

Ask anything

Chat with the codebase — every answer is grounded in the actual source via retrieval, with file citations.

🧭

Agentic triage

Not a blind file dump — an LLM reasons about the file tree to pick entry points, config, and core modules worth reading.

🗺️

Architecture diagram

Auto-generated Mermaid diagram of module relationships or request flow, rendered instantly in your browser.

💬

Chat with the repo

Ask follow-up questions — answers are grounded in the actual code via retrieval, with file citations.

Free. No catch.

Why Second Read exists.

Every engineer knows the feeling of opening an unfamiliar repo and not knowing where to start. Second Read exists to close that gap in under a minute — it reads the file tree, reasons about what actually matters, and hands you an architecture diagram, a plain-English summary, and a chat interface grounded in the real source. No blind file dumps, no generic filler — every answer is traceable back to the actual code.

Built solo by Priyabrat Dalbehera, a GenAI engineer, as a tool to make his own life easier when picking up open-source projects — and shared because every engineer needed one.

Need help? We're here.

Does this work on private repos?

No — Second Read reads repos via the public GitHub API, so only public repositories can be analyzed.

Is there a usage limit?

The shared free key allows 2 analyses per hour per visitor, to keep it fair for everyone. Need more? Paste your own free Groq API key when prompted — it's used only for your requests and never stored on our end.

Why did my analysis fail?

Usually because the repo doesn't exist, is private, or is empty. Double-check the URL and that the repo is public.

Do you re-analyze a repo every time?

No — results are cached per repo, so revisiting the same one loads instantly instead of re-running the full pipeline.

Still stuck? Open an issue on GitHub or reach out directly on GitHub.

Stop reading code cold.

Paste any public repo above and get oriented in under a minute.
