The record

Product: Comail is a fast, keyboard-driven email client that keeps the mailbox on the user's computer.
Email providers: It works with Gmail, Microsoft 365/Outlook, and IMAP providers including Fastmail and iCloud.
Calendar integrations: Its built-in calendar syncs both ways with Google Calendar, Fastmail, iCloud, or any CalDAV server.
Inbox features: Features include keyboard shortcuts, a command palette, split inbox, snooze, scheduled send, undo send, and bulk triage.
Search and AI: Comail offers keyword and semantic search, plus optional AI summaries, reply drafting, proofreading, commands, and inbox questions.
AI providers: Optional AI features work with OpenAI-compatible providers, including local providers such as LM Studio, using the user's own key.
Privacy: The project says mailbox sync and search run on-device, credentials are stored in the OS keyring, and Comail has no telemetry.
Offline use: Users can read, search, write, and triage mail offline, with changes syncing after reconnection.
Desktop downloads: The release page lists macOS universal DMG, Windows x64 setup EXE, and Linux AMD64 AppImage or DEB downloads.
Account setup: Gmail and Microsoft sign-in require users to configure their own OAuth app registration once; other IMAP accounts use an app password.
Support: The README invites feedback by email at [email protected] and accepts bug reports and feature requests through GitHub Issues.
License: Comail is released as free software under the GNU Affero General Public License v3.0.
