retune is free if you run your own copy. it runs on your own computer, with an agent that builds what you ask for.
chatbase is a good product. i'll say where it's ahead first, then the two things retune does that it doesn't.
chatbase is a bigger company and has more in it. i read its homepage on november 3, 2026. it listed agents that answer in chat, email and voice, and on whatsapp and slack. it has a helpdesk where people and the ai work the same conversation, and connections to crms.
it also has security audits a big buyer may ask for, like soc 2.
if you need any of those today, chatbase is the better fit. retune doesn't answer email or phone calls, and it has no audit report to hand to a buyer.
the first thing is that copy. it's yours, and you can start on retune.so instead if you'd rather.
the second is what happens when something's missing. if you want a feature that isn't there, email me and tell me what it is. i built the features on the homepage, each one in its own copy of retune. i can build yours in your copy.
dj's line on it is "if anyone signs up and wants it, we just give it to them."
i'll be wrong sometimes. so look at the new feature before your customers see it.
if you're leaving a bot because it keeps telling people it doesn't know, start with the gaps tab.
the clinic in the video is acme dental. i made it up to show the feature.
every question your bot missed lands there, grouped. the same question asked five ways is one card. you open it and see every way it was asked.
you write the answer once, or let ai draft it with blanks for the facts it can't know. after you save, the answer sits on the train tab as a normal source, next to your pages and files. so you can always see what the bot is answering from.
the longer version is when your chatbot keeps saying i don't know.
it fits a small business with one website and a bot that answers questions and collects leads. it fits better if you want to own the setup, or you keep running into a feature your current bot doesn't have.
it won't fit if you need one agent across email, phone and chat, or a vendor with security paperwork. stay on chatbase for that.
a few plain answers:
on wrong answers: when the retune bot doesn't know, it says so, and the question lands in that inbox instead of getting a made-up answer. it can still be wrong when it does answer. when your chatbot gives the wrong answer is about that.
testing your chatbot before launch shows how to keep a list of questions it must get right.
if it's useful, take it. if it's missing something, tell me.
