txt — a connected text filesystem for people and software agents

txt is a fast, local-first editor for plain-text and Markdown notes. It gives people a focused writing surface while exposing the same files, folders, metadata, versions, comments, connections, and sharing controls through a documented HTTP API, TypeScript SDK, command-line client, and Model Context Protocol server. Agents can discover notes, read only the files they need, create or update text with scoped credentials, preserve version history, and move ordinary deletions into recoverable trash. Notes remain useful outside the app because the core format is text rather than a proprietary document model.

Use txt when an agent needs a durable human-readable workspace, when a team wants shared skills and plans to stay reviewable as files, when an automation needs to transcribe or organize notes, or when desktop, mobile, web, and CLI clients must synchronize the same source of truth. Start with the developer portal for authentication and examples, inspect the OpenAPI document for typed REST operations, or connect to the Streamable HTTP MCP endpoint for native agent tools. Public discovery documents require no account; private workspace access uses expiring, least-privilege keys or dots OAuth.
