Principles

We don't publish a roadmap — promises made on a perpetual licence become debts. These commitments hold instead, and stay true by definition.

Your work never depends on paying

Buy Pro once, or subscribe. Either way, if you stop paying, Pro switches off and nothing else changes: your notes, your version history and restoring from it stay free, and anything you encrypted stays readable. A lapsed subscription is Free, never locked out.

Never sees your data

Prompts to your AI provider go on your credential — we never proxy or see them. Your workspace is end-to-end encrypted with a key that never leaves your device.

No cloud lock-in

Sync runs through a folder you already have, or a git remote you host. Tessamark operates no sync service that can go down and take your notes with it.

Plain markdown, always

Your files are readable in any editor today, and in twenty years.

Version history and restore, always free

Data recovery is never gated. Pro sells the presentation of history, never the recovery itself.

Team and enterprise buyers legitimately ask what's coming in the next twelve months — that conversation happens directly, not on a public page. See the changelog for what has actually shipped.
