An AI assistant that books the table for you

That's what Gravel is designed for: you text what you want, it comes back with two options, and it acts on your pick. In the example conversation above you write “table for 4 friday, somewhere italian near maya’s.” Gravel answers with two options: “Trattoria Sole has 7:45 or Osteria Nona has 8:15. Both 4.7★. Which one?” You write “nona.”

In the example, Gravel books it and tells you: booked for 4 at 8:15 PM Friday, and the invite went to Maya, Sam and Jess. That is two short messages from you for a table, a time and a guest list.

Text it the way you would text a friend. Say how many people, which night, what kind of food and roughly where. A loose request is fine: “somewhere italian near maya’s” was enough.

Gravel is designed to narrow the choices to two, each with a time and a rating, so you can answer in a word. You do not scroll a list or compare tabs.

It is designed to book the table and invite the people you are going with. In the example it confirms the party size, the time and who got the invite, all in one message.

Your pick is the yes. There is no second question.

Nothing is booked until you choose. If neither option works, tell it what to change.

During early access, Gravel may hand you the last step, with the details ready, instead of finishing it itself.

Invites and messages to other people speak for you, and so does anything that costs money, so Gravel's defaults are conservative: it checks with you first. When Gravel acts for you, it presents itself as an AI assistant, never as a person. For each kind of action you can pick one of four levels, from just do it to hand it to me. See how it works. Text “pause” and all background work stops until you say so.

Gravel works from the messaging app you already use, plus the email and calendar you connect. Connect a calendar (Google Calendar, Outlook Calendar, iCloud Calendar or any CalDAV calendar) and Gravel can see when you are free. It starts read-only and asks for more access the first time it needs it.

This example conversation was recorded in Apple's Messages app. During early access Gravel works in WhatsApp and Telegram, and iMessage is coming. The restaurants are examples, and Gravel has no partnership with them or with any restaurant. Gravel costs €12 a month; see pricing.
