FactVerify vs Groundery

FactVerify is a web-based service that automatically checks claims, viral posts, breaking headlines, articles, webpages and documents. It returns an evidence summary, confidence percentage and linked sources. Its four-stage process identifies a testable proposition, uses primary records, examines context and counter-evidence, then produces a calibrated verdict. The retrieval engine can parse court dockets, statutory texts, peer-reviewed journals and agency datasets; listed primary sources also include SEC filings and government datasets. Confidence percentages describe the coherence and corroboration available when analysis runs, not mathematical certainty. Accounts include five automated checks each month, while the homepage offers one check without an account. Real-time checks are private by default and are not indexed by search engines. Selected checks enter a public library with ClaimReview schema, permanent audit links and freshness tracking. FactVerify notes that automated models can miss temporal nuance, sarcasm, complex statutory references or breaking developments, and says the service is informational rather than legal, medical, financial, tax or investment advice.

Groundery extracts factual claims from live or recorded material and checks them against sources chosen for each session. Live inputs include a microphone, a browser tab playing audio, or a stream URL such as YouTube Live, Twitch, or Vimeo. The site says live results usually arrive while the speaker remains on the same topic, ranging from seconds to about a minute depending on the evidence. For recordings, it accepts MP3, WAV, M4A, MP4, MOV, YouTube links, or pasted transcripts. Claims are timestamped so reviewers can revisit the relevant moment, inspect evidence, and share or export reports. Source controls can search the web, limit checks to selected sites, or exclude sites. Groundery says it prioritizes authoritative sources and provides direct links for review. It is available on the web and as a Chrome extension. The Free plan includes 3 hours of fact-checking and 10 instant text checks per month; Pro costs $599 a month. Its terms warn that AI-generated results may be inaccurate or incomplete and are informational aids, not definitive judgments. Uploaded content and results remain until deleted or the account closes, with backups potentially persisting for up to 30 days after deletion.
