Hallucinations are a bug we worked hard to fix
Most AI assistants treat hallucinations as something the user is supposed to catch. We treat them as something the system is supposed to remove. Anything that can't be anchored to a cited passage gets dropped before the answer ever reaches you.
Trained to quote, not to invent
Cemented AI asks the underlying model for exact quotes from the retrieved sources, then verifies each one. That's what makes verification tractable — most of the answer is already pulled straight from the document.
Verified before it ships
Each generated quote is checked against the cited passage. If the match score falls below threshold, the quote is removed and the model is asked to try again with what it actually has.
"Not found" is a valid answer
When the source doesn't support an answer, the model says so plainly. The most expensive bug in AI workflows is a confident wrong answer — making refusal a first-class output is the simplest way to prevent it.
Hallucination FAQ
- Does this guarantee zero hallucinations?
- It strongly biases against fabricated quotes. Free-form summary text can still be imprecise, which is why every quotable claim is the verified kind, and why reviewers should lean on quotes rather than prose.
- Why isn't this how everyone does it?
- Verifying generation is harder than generating, and most assistants optimize for fluency. We made the opposite trade because the teams we serve care about being right more than being chatty.
- What if I already trust my AI tool?
- Then the failure modes are easy to spot — paste in a question and check the answer against the source. The point of Cemented AI is to do that step automatically so it happens every time.
- What does it cost?
- All plans get the same anti-hallucination guarantees. See pricing.
