| Fact-check a video or podcast from a link | Paste a YouTube/TikTok/Reel/podcast URL — it transcribes and analyzes the audio automatically | No video or audio ingestion pipeline; you'd need to source a transcript and paste the text yourself |
| Output format | A 0-100 credibility score per individual claim, each with linked supporting or contradicting sources | Freeform conversational answer; with web search on, responses cite source links — but no per-claim scoring |
| Fact-check while you watch | Chrome and Firefox extension runs against the video in the tab and surfaces relevant viewer comments in sync | Chat interface only — web app and iOS/Android apps; you leave the video to ask a question |
| Deepfake / AI-generated media signals | Flags synthetic-media indicators alongside logical fallacies in the claim breakdown | Not a feature of the DeepSeek assistant; the lab publishes separate open-source vision models, but that's a different tool |
| General-purpose work (code, writing, math, analysis) | None — BSmeter only does claim verification on video and audio | Genuinely strong across coding, math, long-document analysis, and reasoning; V4 ships a 1M-token context window |
| Open weights and self-hosting | Hosted service only; no downloadable model | Flagship models published as open weights on Hugging Face under MIT license — self-host, fine-tune, run fully offline |
