I Built Universal AI Memory for Developers - Here's What I Learned

#productivity #opensource #ai #typescript

I built Context Sync because I was tired of losing context between AI tools

GitHub logo Intina47 / context-sync

Local persistent memory store for LLM applications including continue.dev, cursor, claude desktop, github copilot, codex, antigravity, etc.

Context Sync

Local-first memory layer for AI development tools via MCP.

Install and auto-config (60 seconds)

  1. Install globally:
npm install -g @context-sync/server
Enter fullscreen mode Exit fullscreen mode

  1. Auto-config runs on install. Restart your AI tool.

  2. Verify tools:

  • Claude Desktop: Tools list
  • Cursor: Tools list
  • VS Code/Copilot: Copilot Chat -> Agent mode -> Tools
  • Continue.dev: open Continue panel
  • Codex CLI: codex mcp list
  • Claude Code: claude mcp list

If auto-config fails, see docs/TROUBLESHOOTING.md and docs/CONFIG.md If you installed locally (non-global), auto-config does not run.

Optional: Notion setup

context-sync-setup
# or
npx context-sync-setup
Enter fullscreen mode Exit fullscreen mode

Supported platforms

  • Claude Desktop
  • Cursor
  • VS Code + GitHub Copilot
  • Continue.dev
  • Zed
  • Windsurf
  • Codeium
  • TabNine
  • Codex CLI
  • Claude Code
  • Antigravity (Google Gemini IDE)

First-time workflow

1) set_project({ path: "/abs/path/to/project" })
2) recall()
3) read_file({ path: "src/index.ts" })
4) remember({ type: "decision", content: "Use SQLite for local storage" })

Tool reference: docs/TOOLS.md

Data and config

  • Database: ~/.context-sync/data.db
  • Config: ~/.context-sync/config.json
  • Install status: ~/.context-sync/install-status.json
  • Custom DB…

Ever start a conversation in Claude Desktop, then switch to Cursor and have to explain everything again?

Yeah, me too. Every single day.

So I built Context Sync.

What it does

Keeps your context when you switch between AI coding assistants.

  • Start in Claude Desktop
  • Switch to Cursor
  • Your decisions, conversations, project context follows you

Works with Claude, Cursor, Continue.dev, Windsurf, Zed, and anything that supports MCP.

How it works

Local SQLite database. TypeScript. Model Context Protocol.

npm install -g @context-sync/server
Enter fullscreen mode Exit fullscreen mode

That's it. No config. No signup. Just works.

The last 30 days

  • Launched on Product Hunt (#17 that day)
  • 1,300+ developers using it
  • Added to MCP Registry

Still feels surreal.

What I learned
Ship before it's perfect. v1.0 had bugs. Users reported them. I fixed them. The project got better because people used it.

If you have a problem, others do too. I built this for myself. Turns out 1,300 other people had the same frustration.

Open source works. No landing page. No marketing. Just GitHub. Word spread naturally.

Try it

npm install -g @context-sync/server
Enter fullscreen mode Exit fullscreen mode

It's free. Open source. Local-first (your data stays on your machine).

⭐ Star on GitHub if this solves your problem.

What's next
Honestly? Just making it better based on feedback.

If you try it and something feels off, open an issue. I respond to all of them.
