TablaCognita
A collaborative markdown editor that runs entirely in your browser and exposes 17 MCP tools for document manipulation. Your AI can read sections, replace text with fuzzy matching, request edit locks, and manage snapshots while you work in a live CodeMirror instance. The relay server is stateless, all document state lives in your browser, and every AI edit flows through the same undo stack as your own typing. Connect via stdio for Claude Desktop or HTTP for remote clients. Useful when you want real-time AI collaboration on long-form writing without sending your documents to anyone's server, with section-level coordination that doesn't break when you rename headings or restructure content.

TablaCognita
Co-write with any AI. In your browser. No data on anyone's server.
TablaCognita is a browser-based Markdown editor where AI is a first-class participant, not a feature bolted onto a text box. Select text and send it to your AI. Watch edits land in real time. Undo anything. The AI sees the document through MCP tools — the same protocol that powers Claude Desktop, Cursor, and every other MCP-capable client.
Your document lives in your browser. The relay server is a stateless wire. Nobody stores your writing.
