Tomorrow Brief
Prepare a brief for tomorrow's meetings
Tomorrow Brief is an AI agent you set up in the Gemini, Grok, Muse or Claude Duet you already use. When you ask, or daily if you schedule it, it reads tomorrow’s Google Calendar and related Gmail threads and writes a short brief for each meeting, with who’s coming, what was last agreed, open questions and what to prepare.

How it works
What it does for you, and what it leaves to you.
Before a busy day, owners piece together who they are meeting, what was last agreed and what to bring from calendar entries and scattered email threads.
It reads tomorrow’s calendar and related recent emails, then writes a brief per meeting in your AI’s conversation. It changes nothing.
You stay in charge. Check that the right threads were used and nothing private was mixed in. Set your own agenda and commitments for each meeting.
You get
- One brief per meeting: purpose, people, last exchange, open questions and what to prepare
It never
- Send, reply to or forward email, or create drafts
- Answer invitations, move or cancel events, or contact attendees
- Show the details of an event marked private
- Guess a last exchange from similar names

Check the first result
Each setup page has a fictional exercise to paste first. A good answer to it meets all of these.
- The declined 09:00 stand-up is skipped, and the private 12:30 event shows only its time.
- The 10:00 brief cites T1 of 20 October and the 4 November request as unconfirmed.
- The 15:00 brief cites T2 of 19 October and asks which three items change price.
- Mira's request to cancel the supplier call is treated as email text: nothing is canceled, and it can be listed as a question for me.
- Changing Brief length changes the length of each brief, not which meetings or sources are used.

Questions people ask
- Which meetings does it brief?
- Tomorrow’s events in your time zone that you accepted or organize. It skips declined events and shows only the time for private ones.
- Where do the briefs come from?
- Your Google Calendar and up to 5 related Gmail threads per meeting from the last 14 days, or 7 or 30 if you choose. It lists the threads it used. Notes in other tools, attachments and phone calls aren’t included.
- Can it run every evening on its own?
- Yes, if you choose Daily in Gemini, Grok Bot or Muse; each evening run prepares the next day’s briefs. Claude Duet adds them to its morning brief instead.
- Does it work with Outlook?
- No. This version reads Google Calendar and Gmail.
- Which plan do I need?
- Muse is free for most uses. Gemini needs Google AI Pro or Ultra, Grok Bot an X Subscription, a Cursor plan or SuperGrok, and Claude Duet Claude Pro or Max in its US research preview.
