The Mind Cache for Your AI Dialogues.
Stop losing your best insights to transient chat boxes. MindCache captures your conversations from ChatGPT, Gemini, Claude, DeepSeek, and Yuanbao, organizes them into topics with AI, and saves them as lasting notes — your mindcaches.
100% Free · Open Source · Private by design
- Chat as usual — on ChatGPT, Gemini, Claude, DeepSeek, or Yuanbao. Nothing changes about how you work.
- One click, AI organizes — the browser extension captures the conversation, and an LLM distills it into topics with short briefs. You review everything before anything is saved.
- Save notes that grow — keep the topics worth remembering. Related topics merge into your existing mindcaches over time, so your knowledge base stays coherent instead of fragmenting.
| Repository | What it is |
|---|---|
 extension |
Browser extension (WXT + React). One-click capture from supported AI chat sites, with your review before anything is saved. |
 server |
Self-hostable backend (Go, single static binary or Docker). Distills captures into topics with any OpenAI-compatible LLM, with deduplication, full-text search, and pluggable storage. |
 dashboard |
Web dashboard (React). A calm place to browse, read, and manage every mindcache you have saved. |
| Desktop app | Server and dashboard in one free tray app — no Docker, no command line. Ships with MindCache Try, a free built-in LLM so you can start without any API key (rate-limited, best-effort), and a free Cloudflare Tunnel for remote access. |
| mindcache.fyi | Website, documentation, and download page. |
All three core pieces are MIT-licensed. The desktop app and its Try gateway are the only closed-source components — convenience layers, not lock-in: your data lives in your own storage, and you can switch to your own LLM endpoint at any time.
Everything runs on hardware you control — your laptop, a home server, or a VPS. Your AI provider keys, your storage, your rules. No cloud service you must use, no analytics, no tracking.
The quickest start is the desktop app — it bundles the server and dashboard in one download, with a setup wizard that offers the built-in free LLM (no API key needed) or any endpoint of your own. Prefer full control? Run the server yourself, install the extension, and browse your notes in the dashboard — see the quick start.
