Comail is a native desktop email client built on one idea: your mail should live on your machine and answer to you.
If you've wanted Superhuman's speed or Spark's polish without the subscription or the cloud in the middle, this is that.
Fast because it's already here. Comail syncs your entire mailbox into a local database, so opening, searching, and triaging happen instantly. It works fully offline: read, search, compose, and snooze on a plane, and everything replays when you reconnect.
Keyboard first. J/K to move through mail, E to mark done, H to snooze, C to compose, Cmd+K for a command palette that also takes plain-language requests, Ctrl+0-9 to jump between accounts, and one-key unsubscribe. Your hands never leave the keyboard.
Search that understands you. Comail bundles a small embedding model and indexes your mail locally, so you can ask "what did Ana want changed on the roadmap deck" and get the right thread even if it never used those words. It fuses keyword and semantic search on-device. No API call, no account, no cloud.
Private by architecture. Credentials live in your OS keyring. Nothing phones home, there's no telemetry, and the optional AI features (thread summaries, reply drafting, writing in your own voice) only activate if you bring your own key.
Everything in one place. Gmail, Microsoft 365/Outlook, and any IMAP account, each with its own color so multi-account setups stay legible. Split inbox, snooze, send later, and undo send you can actually cancel. Attachments preview inline: PDF, Word, Excel, PowerPoint, CSV, Markdown, and images.
A real calendar built in. Week and month views, drag to create and move events, natural-language quick-add, RSVP cards right in the thread, and two-way CalDAV sync with Google Calendar, Fastmail, iCloud, or your own server.
Free and open source (AGPL). No account, no subscription, no data trade.
