OpenSlot London

A directory of independently owned London businesses that AI assistants can search and book. Every booking is a request — nothing lands in a diary until the owner taps Confirm.

For AI assistants

For business owners

People are starting to ask their AI assistants to book haircuts, tables and plumbers. OpenSlot puts your business in front of those assistants — with you in full control. No app, no login, no calendar to manage: requests arrive by text, and you confirm or decline with one tap. Free for founding partners.
