What is TabMail?

TabMail is available as a standalone iPhone email client and an AI assistant add-on for Thunderbird. It works with existing Gmail, Outlook, iCloud and IMAP inboxes, offering suggested replies, conversational editing, email triage and chat with your inbox. The Thunderbird add-on also provides composition autocomplete.

The iPhone app is written in Swift and SwiftUI; the Thunderbird add-on is written in JavaScript with HTML and CSS. Both clients are open source under MPL 2.0. Thunderbird local search uses a separate Rust native helper. Source repositories are TabMail/tabmail-ios and TabMail/tabmail-thunderbird on GitHub.

Hosted AI uses a separate proprietary backend with paid subscriptions and a two-week card-free signup trial. The iPhone app requires iOS 26 or later. The Thunderbird version requires Thunderbird, the TabMail add-on and its native helper; follow the official website installation instructions.
