About Zenotion
A calm, markdown-first workspace for specs, RFCs, and daily notes — organized, autosaved, and free. No block editor learning curve, no subscription for the essentials.
Why Zenotion exists
Developers already think in markdown — READMEs, PR descriptions, issue templates, and docs. Zenotion brings that same workflow to personal and team notes without forcing you into a heavyweight block editor or another monthly subscription.
The platform is free forever. AI is optional and powered by your own API keys, stored locally in your browser — never on our servers. You pay only your provider, with no markup from us.
What you get
Everything you need to capture, organize, and share notes — without fighting the tool.
Markdown + live preview
Split-pane editor with sanitized GitHub Flavored Markdown preview — write the way you document code.
Folders & tags
Group specs, sprints, and snippets. Tag by team or topic and find anything in seconds.
Autosave & version history
Every edit persists in the background. Roll back to earlier versions when you need to.
AI command palette
Summarize, rewrite, outline, extract tasks, and more — one shortcut, bounded to your note.
Public share links
Publish RFCs, runbooks, or docs with a URL when you are ready to ship.
Private by default
Your notes are scoped to your account. Public sharing is always an explicit opt-in.

Built because every developer deserves a calm place for notes — without another subscription eating into side-project budgets.
Under the hood
A production-shaped stack with structured API responses, user-scoped data access, and multiple Next.js rendering strategies — SSR for protected routes, SSG and ISR for public pages.
Built by a developer, for developers
