Synapse automatically captures your AI coding sessions from Claude, Cursor, Codex, and Gemini. When you go idle, it distills the valuable parts — decisions, architecture, learnings — into a searchable workspace your tools can read next time.
Hundreds of sessions full of decisions, architecture, and debugging insights
Trapped in chat logs you’ll never scroll back to
Every morning, you re-explain your own project to your own tools
The knowledge is there — it just never gets extracted
A background daemon silently records your sessions from Claude Code, Cursor, Codex, and Gemini
An LLM extracts decisions, architecture, and learnings — the signal from the noise
Next session, your AI tools search the workspace and already have context from every past conversation
Sign up, start capturing. Your sessions become knowledge automatically.
$ npm install -g synapsesync-mcp && synapsesync-mcp wizard && synapsesync-mcp capture startWorks with Claude Code, Cursor, VS Code, Windsurf, and any MCP client.
A background daemon watches Claude Code, Cursor, Codex, and Gemini. No plugins, no prompts, no manual saving.
An LLM reads your sessions and extracts decisions, architecture notes, and learnings. Signal from noise, automatically.
Knowledge captured from Claude is available in Cursor. From your laptop to your desktop. Across your whole team.
Search by meaning, not keywords. “Auth flow” finds documents about login, session tokens, and OAuth.
Set a passphrase and content is encrypted before it leaves your machine. The server never sees plaintext.
A lightweight background daemon watches where your AI tools store session data on disk (JSONL for Claude Code, JSON for Cursor, etc.). When files change, it parses them into a standard format. No plugins needed — it works by watching the filesystem.
When a session goes idle, Synapse sends the transcript to an LLM (your choice of Anthropic, OpenAI, or Google) that extracts decisions, architecture notes, and learnings. Trivial exchanges are skipped. Only the valuable stuff makes it into your workspace.
Capture works with Claude Code, Cursor, Codex CLI, and Gemini CLI. The knowledge workspace is accessible from any MCP-capable tool, including ChatGPT, Windsurf, VS Code, and GitHub Copilot.
Yes. You can enable end-to-end encryption with a passphrase — content is encrypted on your machine before it ever hits the server. We cannot read your files. Captured sessions are stored locally by default and only sync to the cloud if you have an API key configured.
Free tier: 50 files, 3 connected devices. Capture and local storage are free with no limits. Plus at $5.99/mo for cloud sync, team sharing, and more projects. You provide your own LLM API key for distillation.
Capture sessions, distill knowledge, remember everything. Free to start.
