Parafact

Parafact is a fact checking tool for written text. A user pastes in an article, essay, report or any other passage, whether written by a person or generated by AI, and the tool checks the claims it contains against reliable sources in real time. It is aimed at journalists, researchers, students, legal teams, content creators, marketers and communications staff who want to verify copy before publishing. Each fact checked claim comes back with a label of accurate, inaccurate or subjective, a link to a supporting source and a natural language justification, so the user can trace where the information came from. The process is fully automated and runs in seconds on pasted text. Parafact also offers a developer API. A single POST request to the factcheck endpoint with a block of text returns a list of claims, each with its label, source and justification, which allows teams to build automated checking into content moderation or publishing workflows. API access is requested through the site. The vendor does not publish plan prices on its site. Anyone interested in the web tool or the API needs to use the site's sign up or access request flow to find out terms.
