Cekat.ai Turn out it's just simple workflow and i don't know what the hype is. I mean they build really cool stuff and i heard they also have their own model using argi.id which is impressive. You can build your own using ai api from google, open ai or anthorpic (overkill) for answering the 'customer' chat, i wont do that but i think i know the workflow (i've create MANY web-apps like that before and i know what they're doing there) I'll give you the simple workflow and the details-one, imagine it's just chat with ai with under-rules (ai-agent) and the 'customer' can set their own rules which here is 'their product' information.
