AI Email Assistant
An AI email assistant for any inbox
Tomorrow reads your mail, understands the thread, drafts the reply, and turns email into real work across your tools. It works on Gmail, Outlook, Proton, Fastmail, and custom domains.
Works beyond Gmail
Use one-click Gmail OAuth or native IMAP/SMTP for every other mailbox.
Chat-to-action
Ask it to create issues, draft invoices, update CRMs, or make tasks from email.
Approval-first
Tomorrow prepares actions, then waits for your explicit approval before anything runs.
Inbox
A real email client
Read, search, write, and send from Tomorrow as your everyday inbox. The assistant is a layer on top of the client, not a digest service or sidecar.
Context
Understands the thread
Tomorrow uses the email thread as context, so commands like "reply with my availability" or "turn this into a Linear task" start from the actual conversation.
Control
No autonomous surprises
It can draft, summarize, prepare, and queue work. Sending or changing anything still requires your approval.
Compare
Built for the non-Gmail world
If Gmail-only tools do not fit your mailbox, start with the Shortwave comparison or the custom-domain email guide.
Stop switching between your inbox and your tools
Connect your mailbox, tell Tomorrow what should happen, and approve the work from the same place you read the email.
