Bots that work for you, on your own AI plan.

Extent is an iPhone and Mac app for a few persistent bots: one for everything, one for money, one for trips. Each bot is one long conversation. It runs on the Claude or ChatGPT plan you already pay for, with the model you pick.

If you connect Gmail and Google Calendar, your bots read them and message you first when something needs you, like a meeting that moved or a reply you're waiting on. They stay quiet otherwise. Each user also gets a computer in the cloud that bots use to sign in to sites, fill in forms and run errands. You can watch it, or take over the screen.

Nothing irreversible happens without your tap. A bot writes an email as a Gmail draft and shows it to you, and the mail goes out only when you tap Send. The same goes for calendar changes and anything else that others can see.

Extent is in early access. Questions, support or a deletion request: hello@extent.sh.

ExtentBot

When a bot reads a public web page for a user, the request comes from the Extent server with the user agent ExtentBot/1.0 (+https://extent.sh). It fetches only the pages a user's bot asked for, and builds no index. To ask us to stop, write to hello@extent.sh.
