factfully is a Chrome extension that acts as an AI-driven misinformation checker, evaluating statements in the pages you read and helping you gauge whether content is likely true or biased.
Ranks statements across metrics such as sensationalism, testability, and political bias to flag likely false content.
Tokenization separates objectively checkable claims from subjective opinions before verification.
Scans thousands of websites to see whether a statement is backed by other sources.
Delivered as a Chrome extension so checks sit alongside the content you are reading.

Works natively inside Chrome, Safari, Firefox, Edge, Windows, Mac, Google Docs, MS Office, and mobile keyboards to flag grammar mistakes, rewrite tangled sentences, and shift tone toward confident, empathetic, or executive registers.
Deploys contextual AI agents that predict how a target audience will react to a draft, locate credible supporting citations, grade essays against rubric criteria, and generate drafts using up to 2,000 monthly prompts on Pro.
Scans text against billions of web pages and academic databases for accidental plagiarism, detects AI-generated passages, and logs transparent document provenance via Authorship reports in Google Docs and Word.
