Documents with superpowers.
Notes that actually do things. Specs that track themselves. 35 block types, AI chat, and an open format you own forever.
Typed documents
35 block types with schema validation. Decisions, data tables, tasks, conversations — not just prose. Structure your thinking, not just your words.
AI chat modes
Research. Plan. Build. Three AI modes that understand your documents and help you write, organize, and ship — from a single chat interface.
Multi-target rendering
Same source file renders to HTML, PDF, terminal, and Markdown. Write once. Publish anywhere. No export plugins, no conversion tools.
Built for teams. Built for you.
For software teams
Typed specs and decision docs replace scattered wikis. Automatic time-per-status tracking means no timers to start and no time to log. Knowledge docs, task management, and AI chat in one workspace.
For individuals
Quick capture notes with 35 block types — not just text paragraphs. Search everything instantly. Own your files forever as plain text on disk. AI chat helps you research, plan, and write. VS Code extension included.

SurfDoc files are plain text. They live on disk, in git, in any filesystem.
No cloud dependency. No vendor lock-in. A .surf file without a renderer
is still readable markdown.
