Your project's docs,
at terminal speed
doku.md is a fast, native desktop app for browsing, searching, and understanding Markdown documentation — built for developers who live in specs, plans, and tasks.
Everything you need to recover context
Full-text search
SQLite FTS5 indexes every Markdown file the moment you open a project. Search by title, path, or content — results in under a second, even across thousands of files.
Live sync
A file watcher keeps the index up to date automatically. Create, edit, move, or delete files — doku.md reflects the change within seconds, no restart needed.
Three-column reading
Navigation, document, and table of contents — side by side. Tabs for multi-document workflows, bookmarks for quick access to what matters most.
Spec-aware
Built by someone who lives in spec.md, plan.md, and tasks.md every day. doku.md understands the structure that AI-assisted development produces.
Plugin system soon
Detect project structures — Spec Kit, OpenSpec, ADRs, changelogs — and surface them with custom views. Planned for a future release.
Works offline
No account, no cloud, no telemetry. Everything runs locally — your documentation never leaves your machine. Semantic search via local AI is planned for a future release soon.
