Frequently Asked Questions

These are the questions we get most. If you don't find what you're looking for, feel free to contact us.

DeepVerify draws on academic databases, established news organizations, government and regulatory sources, and peer-reviewed journals. Each claim is classified as Verified, False, or Uncertain with a confidence score based on the sources it was checked against, and every result links back to the sources actually used so you can check the evidence yourself. For nuanced or fast-moving topics, especially decisions with real financial or reputational stakes, treat results as a strong starting point rather than a final verdict.
