Every answer bot will meet a question it cannot answer. What it does next decides whether your team trusts it. A bot that guesses teaches people to double check everything. A bot that says nothing useful teaches them to ask you again. This guide describes the options and gives you a test.
Three things a bot can do
- Guess. It writes a plausible answer from general knowledge. This is the failure that cost Air Canada: a tribunal held the airline responsible for what its chatbot told a customer, and rejected the idea that the bot was a separate entity.
- Hand the question to a person. The bot says it is not sure and brings in someone who can answer.
- Say it does not know and record the gap, so an owner can write the answer once and the bot has it next time.
What three vendors say on their own pages
We read three product pages on October 20, 2026. Tettra's page says that when its bot, Kai, cannot find an answer, it helps find the right person to answer the question. Runbear's page says its agent tags a person when it is not sure, and hands off with context instead of guessing. Guru's page says it flags knowledge gaps and unanswered questions and routes them to an expert for review.
Two other pages we read, Slite and Notion AI, describe cited answers and verified pages, but did not say what happens when no answer exists. That may be stated elsewhere. We only report what the page said. Check each vendor's current site before you decide.
Why this matters more than the happy path
Anthropic's guide on reducing hallucinations names permission to say 'I don't know' as a basic technique, and says it can sharply reduce false information. A bot that has never been given that permission, or has no document to quote, will tend to fill the gap. The fallback is the part you should test first, because that is where the damage happens.
A six point test for a good fallback
- It says plainly that it does not have an approved answer. No apology paragraph and no hedged guess in the same breath.
- It does not change its mind when the person pushes, claims the founder approved it, or says it is urgent.
- The question goes to one named person with the asker's exact words attached.
- The asker is told what happens next and is notified when there is an answer.
- The answer, once written, becomes an approved answer with an owner and a date, so the same question is covered next time.
- Unanswered questions are visible as a list, so the owner can see which answers are missing most often.
How to run the test in ten minutes
Ask your bot twelve questions that no document answers, such as the office Wi-Fi password, last quarter's revenue or what a colleague earns. Add traps: ask for a best guess, claim an approval, say it is urgent. Ask each three times in fresh chats. Count how often it admits it does not know and what it does next. The free honesty test at askmystartup.com/honesty-test holds a ready set of twelve questions, scores the replies you paste in, and runs in your browser.
How AskMyStartup handles it
AskMyStartup answers only from answers the founder approved. When none matches, the clone says it does not know, tells the asker the founder has been asked, and puts the question in the founder's inbox with the asker's words. It is in private beta and it works as a web page, not inside Slack or Teams.

Common questions
For questions about your own company, no. A guess about a refund rule, a price or a policy can be acted on as if it were true. If you want brainstorming, use a separate tool that does not speak for the company.
They solve different problems. Saying it does not know protects the answer. A handoff gets the person helped. The best fallback does both and also records the gap so it is answered once.
Test it with questions that have no answer, three tries each, and read every reply. A fallback that holds on plain questions but gives way when someone claims the founder approved it is not ready.
Ask them directly and test it yourself. Not stating it is not proof of a problem, but you should not assume the behavior you want.
