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 into every team member's AI chat.

Why?

1. Team Memory: Enables collaboration across dev teams
2. Zero Effort: Helps AI remember context about you
3. Locally Controled: Sync your context in real time with others

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)

File Format

Each chat session produces one .md file:
