# ExplainGitHub API

## ExplainGitHub API lets you build repo-aware AI features

### Customer-facing developer products

Add “ask this repository”, PR summaries, issue copilots, or codebase chat directly into your product experience.

### Internal engineering and support tools

Help engineering, support, QA, or ops teams get answers from private repositories without manually searching code and docs.

### Docs, onboarding, and automation

Power docs assistants, developer onboarding flows, CI helpers, or internal automation that needs repository context.

# History and Chats

## Saved History and Chats — Pick up right where you left off

Ever solve a tricky flow and then forget which files mattered? History keeps your conversations and traces so you can jump back in instantly — across repos.

## Why it’s useful

- Continue a deep dive without rebuilding context
- Share a link to a past trace with your team
- Compare how a flow changed over time

## What’s saved

- Your prompts and follow‑ups
- Cited files and snippets pulled during the chat
- Repo and branch context

## How to use it

1. Ask a question in any repo (“Trace login → session creation → DB writes”)
2. Click History to revisit the conversation later
3. Resume, fork, or share the thread

## Tips

- Name important threads so they’re easy to find later
- Pair History with the repo viewer to see cited files and context side‑by‑side

## Privacy

- You control your data. Remove any conversation at any time
