Coming soon · Linux first

Desktop mail and calendar for Linux, macOS, and Windows.

Hindsight is a local-first client for Microsoft 365, Gmail, and IMAP. Your mail syncs into a database on your computer — we never see it, store it, or train on it. Built for Linux first; same app on macOS and Windows.

Hindsight's mail view: unified inbox across two accounts, a threaded conversation open in the reading pane

Power-user mail, native on your desktop.

Priority inbox, local rules, snooze, meeting scheduling with free/busy, keyboard triage, and a full calendar in one window — without a browser tab or a VM. The app talks directly to your provider and stores everything in SQLite on your machine.

For people who want a dense, desktop mail workflow on Linux (and the same client elsewhere). Leave your email above — we will write when builds are ready.
