| Core question it answers | Are the claims being made actually true? | Was this text likely written by AI? |
| Input it accepts | Video and audio links (YouTube, TikTok, Instagram Reels, podcasts) plus a Chrome/Firefox extension that runs while you watch | Pasted or uploaded text only — no video or audio |
| Factual verification against sources | Every claim cross-referenced against live web sources, scored 0-100, evidence linked | Not attempted — the detector says nothing about whether the content is accurate, only about likely authorship |
| AI-generated content detection | Flags deepfake and AI-generated signals in video/audio media | Purpose-built for text: distinguishes human, AI-generated, and AI-refined writing; premium detects GPT-4 and holds up better against paraphrasing tools |
| Academic writing workflow | None — not built for essays, citations, or coursework | Integrated with Scribbr's plagiarism checker, citation generator, proofreading services, and a large academic Knowledge Base |
| Free access | Free tier for video fact-checking; Basic $3.99/mo, Premium $8.99/mo | Free detector with no account required and unlimited checks, capped around 1,200 words per submission; the higher-accuracy premium detector comes bundled with a paid plagiarism check |
| Reasoning and rhetoric analysis | Flags logical fallacies, surfaces relevant viewer comments in sync, and offers Roast, Analyze, and Learn modes | Not in scope — the tool scores authorship probability, not argument quality |
