Themesmith designs, builds and looks after websites for small businesses, entirely by message. Owners talk to it over WhatsApp, Messenger, Instagram or email. It asks about the business, recommends pages, offers design directions to choose from, then builds and publishes. After launch, a tradesperson can send photos from the van and they're on the site minutes later. No app and no dashboard to learn, though there is one if you want it. Plans from £15 a month.
