ContextSync

Stop re-explaining your code to AI. Collaborative context sharing for VS Code teams.

ContextSync lets teams share AI conversation context automatically. Every chat is saved as a structured .md file, synced via OneDrive to your team's Obsidian vault, and injected as context built into every team member's AI chats.

Currently only for GitHub Copilot - More model support coming soon.

Why?

1. Team Memory: Enables collaboration across dev teams
2. Zero Effort: Helps AI remember context about you and only recall valid topics
3. Locally Controlled: Sync your context in real time with others and hide conversations using private mode
4. 4. Direct Integration: Directly integrate with Copilot using."@contextsync" in chat

Local Context Generation	Real-time Team Sync

How It Works

You chat in VS Code
      ↓
ContextSync saves chat as .md (chat_zayaan_2025-01-15_001.md)
      ↓
OneDrive syncs .md to the team vault
      ↓
Bob opens VS Code → ContextSync loads Zayaan's .md
      ↓
Bob's AI chat has Zayaan's context automatically

Setup

1. Install dependencies

npm install
npm run compile

2. Configure settings (VS Code Settings → search "ContextSync")

3. Open the chat

Run command: ContextSync: Open Chat (Ctrl+Shift+P) OR Type: @contextsync in GitHub Copilot chat

File Format

Each chat session produces one .md file:

---
id: zayaan-01-15_1736934720000
author: zayaan
topic: "How should we structure the auth middleware"
tags: [auth, backend, typescript]
created: 2025-01-15T10:32:00Z
updated: 2025-01-15T10:45:00Z

## Summary
Decided to use JWT with 15-minute expiry and refresh token rotation...

## Key Decisions
- JWT with 15min expiry + refresh token rotation
- Auth middleware lives in /packages/auth

## Context Links
- [[chat_bob_2025-01-14_003]]
