An AI customer support chatbot that refuses to guess
Most support chatbots fail in the same way: asked something their training does not cover, they produce a fluent, confident, wrong answer. This one is built around the opposite behaviour — it answers from your pages, cites them, and says it does not know when it does not know.
Behaviour
How it behaves
Three things it does that you can check, rather than three adjectives.
Every answer is scored for confidence before it is sent. Below the threshold the bot does not attempt an answer at all — it says it does not know and offers to pass the question to a human.
Answers are generated only from content retrieved out of pages you published, and each one cites the URL it came from, so anything it says can be checked against the source in one click.
Accuracy is checked every night: a separate model re-reads the answers your bot gave real visitors and judges each against your own pages. The counts, and every answer it could not support, are on your dashboard.

FAQ
Questions
How is this different from a general chatbot?
A general chatbot answers from what it was trained on. This one retrieves passages from your own site for every question and answers only from those, which is why it can cite a URL and why it can tell when it has nothing to work with.
What happens when it cannot answer?
It says so plainly and asks for an email address so a human can follow up. That refusal is also recorded as a gap, so you can see what customers are asking that your site does not cover.
