A local-first Markdown editor, native on every platform, built on a shared Rust core. No account to create.
Into a shadow git repository you never have to think about.
Not seven days of snapshots — the whole life of the document.
Data recovery is never gated. Pro sells the presentation — visual timeline, side-by-side diff, AI change summaries — never the recovery.
Compared with Obsidian's File Recovery — five-minute snapshots kept seven days, a flat list, no connection to git, with longer history requiring a paid sync add-on. Typora has no version history.
Monaco editor with a rendered preview beside it — Mermaid diagrams, LaTeX via KaTeX, syntax highlighting via Prism.
Wiki-links, backlinks, tags, daily notes, and an interactive relationship canvas — free tier, because it's how you navigate what you already own.
One click, from the editor. Ghost only — nothing else is built or planned.
Not a database, not a proprietary container. Readable in any editor in twenty years.
GitHub, GitLab, a box in your garage — your choice, your account. Tessamark runs no sync service.
The shadow repo is encrypted with a per-workspace key that never leaves the device — we cannot read your notes, by construction.
Your prompts go to your provider on your credential. Tessamark never sees or proxies them. Works with local models too.
macOS and iOS ship today. Windows, Linux, and Android are in progress. One purchase covers every platform Tessamark ships — no per-platform upsell.
Team licences are reassignable seats, volume pricing from 5 seats, one invoice. See team pricing →
