HyperCite
AI chat is something we all use, and hallucinations are something many of us have been frustrated by. We built a cross-disciplinary fact-checking engine for science, medicine, law, and defense that verifies claims against underlying sources instead of letting unsupported text slide by unchallenged. The software is being built to help the Supreme Court of Arizona and is currently trusted in work with the Arizona Court of Appeals, Division Two.
Correct information matters differently depending on the field, but the pattern is the same. In law, a bad citation can distort an argument. In medicine, a confident falsehood can harm a patient. In science, weak grounding can send research in the wrong direction. In defense, inaccurate information can become an operational risk. A probabilistic system will never be perfect, but that does not mean teams have to accept vague answers. Good systems can define approved sources, retrieve the right evidence, compare claims against that evidence, and show people exactly where a conclusion came from.
We approached HyperCite as citation-grounded AI: source traceability, claim matching, strong guardrails, and a genuinely hallucination-resistant retrieval workflow. Under the hood, that means intelligent embeddings systems, state-of-the-art RAG, source-aware evaluation, and data pipelines that create rigorous test sets instead of relying on vibes. The goal is simple enough for anyone to understand: if a model makes a claim, it should be able to show its work.
The technical challenge is making that simple idea hold up in messy real documents. Claims need to be broken into checkable units. Sources need to be chunked, embedded, retrieved, and ranked. Matches need to be evaluated against real criteria: citation coverage, retrieval quality, contradiction detection, missing-evidence handling, and whether the answer is useful without pretending to know more than the sources support. That is how the product checks facts, fights hallucinations, and makes AI safer in truth-critical domains.
