Tasks as markdown files
Every task is a markdown file with YAML frontmatter. Simple to read, simple to write, simple to version control.

Nothing you don't.
Local-first
Your machine, your data
Tasks live on your disk as plain files. Always available, always yours, always under your control.

Branch your tasks with your code. Review changes in PRs. Your project history stays complete.
AI-native
Designed for agents
AI agents read and write your tasks directly as markdown. Zero setup, zero friction.
Plain text
Works with every editor
Vim, VS Code, Obsidian, or anything that opens a file. Markdown with YAML frontmatter.
Works offline
No connection needed
Your tasks are always with you. On a plane, on a train, in a cabin with no signal.
Open source
Free forever, MIT licensed
No subscriptions, no tiers, no limits. Built in Rust, open on GitHub, yours to keep.
// ai-native

// principles
Built on simple ideas
Plain text has worked for 50 years. We think it'll work for 50 more.
Markdown is the source of truth
Everything is a file. Indexes and caches are derived views that can always be rebuilt.
CLI-first, UI-optional
Agents and power users get a fast CLI. Visual thinkers get an interactive Kanban board.
Your data never leaves your machine
No telemetry, no cloud sync, no accounts. Just files on disk that you own completely.
Hackable by design
Plain text means any tool can read it. Any script can modify it. The possibilities are yours.
