In their own words
Avancer Document Fact-Checker
Avancer Document Fact-Checker extracts factual claims from PDF documents and checks them against live web sources. Each claim receives a verified, unverified, or source-not-found verdict, along with evidence and a confidence score. The service checks for factual errors, fabricated citations, and misinformation, and estimates how much of a document was written by AI. Its page estimates about 20 seconds of scanning per 1,000 words. Documents can be checked through the web service, self-hosted options, or an API that accepts a document URL or raw text and returns claim-level results with evidence and sources. Claim extraction and verification are listed for more than 70 languages. Files are processed for the scan and deleted afterward; documents are not used to train models or shared. A free plan includes one scan. Basic costs $12.99 per month and includes 1,299 monthly credits, text scanning, API and webhook access, email support, and PDF report export. A seven-day trial is listed. The maker also lists SOC 2 Type II and GDPR compliance, with ISO 27001 in progress.
Groundery
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.
