AI email for your existing inbox
Supports Gmail, Outlook, iCloud, and IMAP.
Read demo description
The demo introduces TabMail for existing Gmail, Outlook, iCloud, and IMAP inboxes with instrumental background music. It starts on iPhone: a suggested reply is opened for review, a spoken request makes the draft warmer and shorter, the inbox assistant compares flights, and a tag helps triage email.
After “Also on desktop,” it shows Thunderbird: Tab opens a reply, accepts suggested text, and completes a thought. A requested edit changes the draft, the inbox assistant finds a message, and Tab archives an email.
