| Purpose-built for verifying claims in video and audio | The entire product — transcribe, extract claims, verify each one against live sources | A general assistant; fact-checking is something you can ask it to do, not what it's built around |
| Platform coverage for video and audio links | Transcribes the audio itself, so YouTube, TikTok, Instagram Reels and podcasts work whether or not captions exist | Copilot in Edge can summarize videos, but its video summaries lean on existing subtitles or transcripts and are geared toward YouTube |
| Per-claim 0-100 credibility score with linked evidence | Every extracted claim gets its own score and its own sources, listed separately | Returns cited prose answers rather than a structured, scored claim-by-claim breakdown |
| Web-grounded answers with real citations | Cross-references claims against live web sources and links the evidence | Equally strong — Bing-indexed answers with source links, plus deep citations that point into the specific part of a referenced file |
| Deepfake and AI-generated media signals | Flags deepfake and synthetic-media signals alongside the claim analysis | Not a consumer deepfake detector; Microsoft's AI-content watermarking labels media generated inside Microsoft 365 rather than screening third-party video |
| Integration with your OS and daily work apps | A browser extension and a web app — no Office, email, or OS integration | Clearly better — built into Windows, Edge, Word, Excel, Outlook and Teams, with Copilot Vision able to see and discuss your screen in real time |
