Our verdict

For a real site, Tidio and Chatbase are the two free plans worth starting with. Tidio gives you live chat plus a basic chatbot at no cost; Chatbase gives you a free tier to test a chatbot trained on your own content. Landbot, Botpress and CustomGPT.ai are better once you already know what you want to build.
