linden.mdA private home for everything you think, write, and plan.
Linden is your personal knowledge tree: plain Markdown you own, on every device, open to the AI you choose.
Run it on a computer you already own. It reaches your phone and laptop from anywhere in the world, with no port forwarding and everything encrypted in transit, and it gives the AI agents you trust a direct, controlled line to your library.
Your hardware, your data, your rules. Or skip the setup: Linden Cloud runs it for you, with the same app and the same notes you can export anytime.
Get the app for iPhone, iPad, Mac, and Windows. Android is on the way.

What's inside
Open to any AI, with shared memory
Point Claude, ChatGPT, Grok, Gemini CLI, Cursor, or any MCP client at Linden: scoped, revocable access to your whole library. What one agent saves, every agent can recall, so your knowledge compounds instead of resetting.
Agents & memory ›Search by meaning
Vector search fused with keyword search finds the note you half-remember, not just the exact words. PDFs, documents, and images are read and searchable too.
How search works ›A living canvas
Notes, tasks, and to-dos in live Markdown, plus embeds that run real React components, Mermaid diagrams, code, and math: brainstorm an idea and the working mockup appears in the note.
Notes that run software ›Yours, everywhere
Offline-first sync on every device, automatic NAT traversal, publishing to your own address, and a full plain-Markdown export anytime. Self-host it, or run it on Linden Cloud.
