I've tried out quite a few AI chatbots (both from AppSumo and elsewhere) and Tiny Talk is probably the best in terms of core interface/usability and being able to restrict answers to your specified content (and reducing hallucinations or false answers from the chatbot). What I'm not thrilled about, however, is that Tiny Talk adds quite a few tracking scripts and third-party cookies (including ones from Facebook, Clarity, and Bing) to their widget by default with no way to disable them. There are some other features that need to be built out a bit more and improved to make the really useful (such as the "Help Desk" and "Enable Human Support" features), but I expect that will come with time. If I could give it 3.5 or 3.75 tacos, I probably would. But the interface and functionality are strong enough for me to lean more toward 4 tacos than 3. :)
