Typebar (formerly SuperDocs.app) is the document harness for your AI. Lets your AI edit and work with documents the way coding agents work with code.

It finds the exact spot, changes only that, and leaves everything else untouched. About 97% fewer tokens and about 95% cheaper than rewriting the whole document, so a 3-page and a 500-page document cost about the same to edit. Saves 500+ dev hours and $30K+ compared with building it yourself. Used in 50 countries and 21 languages. Invited to Y Combinator Startup School 2026, with non-dilutive credits and grants from organizations like Amazon, Microsoft, Google, Anthropic, and OpenAI. Give your product or your own AI our REST API and MCP server, or use the web app. Self-serve: integrate in under 15 minutes through the API or MCP. Done for you: we build it into your product. Enterprise plans add a white-label option and on-premise or self-hosted deployment.
