One command center for every inbox

Every inbox, summarized, with the to-dos pulled out.

Signal funnels your Gmail accounts into a single dashboard, gives each message an AI summary with its action items, and turns those into tasks and calendar events in a tap.

Signal is a private productivity dashboard for people who run more than one thing. It brings several Gmail inboxes together, reads and organizes your mail, and uses AI to summarize each message, surface what needs doing, and draft replies — so nothing important slips between accounts.

Unified inbox

All of your Gmail accounts funnel into one view, colour-coded and filterable, with per-account focus when you need it.

AI summaries & action items

Open a message and get a one-line gist plus the concrete to-dos, each convertible to a task or calendar event in a tap.

Drafts in your voice

Generate a ready-to-send reply in the tone you choose, tuned to the account it came in on.

Tasks & calendar

Deadlines, follow-ups, and a merged calendar keep every venture's commitments in one place.

How your Google data is used

With your permission, Signal reads your Gmail messages to display and summarize them, can send replies you approve, and can create calendar events from your mail. Your email content is processed only to provide these features to you. Signal does not sell your data or use it for advertising. Full details are in our Privacy Policy, which follows the Google API Services User Data Policy, including the Limited Use requirements.
