Groundery vs Veritier

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.

Veritier extracts checkable claims from text, URLs, PDFs, and images, then compares them with live web evidence or private references. Results provide a verdict, confidence score, plain-language explanation, and source links. The service is available through a REST API, MCP server over Streamable HTTP, local stdio proxy, and browser interface, with parsing and OCR built into its pipeline. The attest_action endpoint checks named records such as npm, PyPI, CourtListener, SEC EDGAR, and the U.S. Code, blocking actions when records cannot be confirmed. Attestations create Ed25519-signed Claim Credentials that can be checked through JWKS and revoked; credentials remain for 400 days. Requests can use webhooks and signed retries. Free-tier text may be retained and used to improve models, while paid-tier payloads are processed ephemerally and excluded from foundation-model training. The free tier allows 25 verifications monthly; paid plans start at $19.99 a month. Verdicts and confidence scores are probabilistic.
