The source never existed.
A plausible paper title, author, DOI, court case, or policy link can be fabricated while looking perfectly formatted.
Why AnswerCheck exists
It sounds confident.
It can still make things up.
The hardest errors are not obvious nonsense. They are polished answers, exact-looking numbers, and citations that seem real—until you check them.
The trust problem
Confidence is generated.Truth must be checked.
Users describe the same exhausting pattern: the answer looks good enough, then a source does not exist, the model doubles down, and the time saved by AI disappears into checking everything again.
The source exists—but says something else.
The answer may exaggerate an association into causation, swap populations, or attach a real citation to the wrong conclusion.
The fact was once true.
Routes close, regulations change, prices move, guidance updates, and products evolve. Fluent answers can silently preserve old reality.
Many links can still mean one source.
Ten summaries may all copy the same press release. Repetition creates visibility, not independent confirmation.
Our role
AnswerCheck is the evidence layerbetween an AI answer and your decision.
We do not ask you to stop using AI, and we do not replace your judgment with another unexplained score. Select the answer that matters; AnswerCheck isolates its claims, retrieves inspectable sources, and shows where the evidence supports, conflicts with, or cannot verify them.

How judgment stays yours
Not another confident answer.A visible trail of evidence.
Claim by claim
Broad prose becomes specific dates, numbers, citations, quotations, and causal claims that can actually be checked.
Sources you can open
Evidence remains linked so you can inspect the institution, publication date, methodology, and original context yourself.
Reasons, not verdict theater
AnswerCheck explains scope mismatches, stale evidence, source conflicts, and missing context instead of hiding them behind certainty.
Uncertainty remains visible
When the evidence is insufficient or mixed, the honest result is uncertainty—not a forced true-or-false label.
AI sounds right. AnswerCheck finds what it made up.
