## features
Marktide is a real Mac app — not a browser in a costume. It opens instantly,
works entirely offline, and every note is a plain .md file in a folder you choose.
Select text and a floating palette appears — six luminous colors that make key lines impossible to miss, saved as plain markdown.
Type [[ and autocomplete connects your notes. The backlinks panel shows every note that points here.
A thought strikes while you're in another app? One hotkey, type, done — filed to your vault's inbox with a timestamp.
Your document is already a slide deck. One key turns headings and dividers into beautiful full-screen slides.
Every command in the app, one fuzzy search away. Your hands never leave the keyboard.
KaTeX equations and Mermaid diagrams render live in the preview — and in your PDF exports.
A master password and Touch ID keep curious eyes off your notes on shared screens. Auto-locks when your Mac sleeps.
A vault is just a folder. Sync it with iCloud or Dropbox, version it with git, open it in any editor. No lock-in, ever.
Smart paste turns copied web pages into clean markdown. Tab hops through table cells. Vim mode, if that's your thing.
## privacy
Most apps ask you to trust their privacy policy. Marktide's architecture makes the promise for us: there is no server to send your notes to.
Fix grammar, rewrite for clarity, summarize — powered by Apple Intelligence, running entirely on your machine. No cloud, no API key, no monthly AI fee.
Marktide doesn't know who you are and doesn't want to. Nothing is collected, tracked, or phoned home. The purchase is handled by Apple.
Notes are plain markdown on your Mac, protected at rest by FileVault like the rest of your data. Delete the app and your notes remain untouched.
## pricing
## faq
In plain .md files, in folders you choose on your Mac. Marktide has no database and no proprietary format — your notes open in any text editor and outlive any app, including this one.
Completely. Editing, preview, search, export, even the AI — everything runs locally. The only optional network use is fetching math/diagram libraries, and you can vendor those for full offline use.
An Apple Silicon Mac running macOS 13 Ventura or later. The on-device AI features additionally require macOS 26 with Apple Intelligence enabled — everything else works without it.
Really. $9.99 once, through the Mac App Store. We can afford that promise because Marktide has no servers to pay for — your Mac does all the work.
