SimplyBook.me is a free-to-start online booking system that lets service businesses take appointments and payments, and it connects to AI assistants like Claude for easy management.
SimplyBook.me is an online booking and scheduling system that lets service businesses take appointments and payments from clients without handling every request by hand. It’s used by over 100,000 service businesses as of late 2026. You can create a free account, add your services, set your availability, and connect a payment method, so clients can book and pay you directly through your own booking page. It suits appointment-based service businesses such as coaching, tutoring, training, and consulting, which is why it fits the kind of session-based businesses people are starting around AI right now.
Instead of loading every business with the same setup, it offers more than 60 custom features that you switch on only when you need them, so your account stays simple at the start and grows with your business. You can add a ready-made booking widget to your own website, or if your site runs on WordPress, you can use the SimplyBook.me booking plugin instead. SimplyBook.me also supports MCP, an open standard for connecting AI assistants to outside tools, which lets you link your account to Claude, ChatGPT, Cursor, or any other MCP-compatible assistant.
