Hey Product Hunt 👋 I'm Will, the maker of Bullsift. I built this because I kept watching long YouTube videos and walking away unsure what was true, what was speculation, and what was straight-up made up. The "Fake Gurus" & "AI Slop" problem on YouTube is getting worse fast — content farms can spin up a polished-looking video in an hour, and the algorithm doesn't care if it's accurate. So I built Bullsift. Open the extension on any YouTube video or paste the link on our website and get: → A "slop score" — how much of this video is low-effort or AI-generated → Every factual claim extracted, with verdicts (true / false / misleading / unsupported) and sources → A trust score for the channel itself, blending AI assessment + community votes → "Deep Sift" mode that uses Gemini 2.5 Pro + grounded web search to verify each claim against real sources Free tier gets you 90 fact-checks a month. Pro ($9.99) is unlimited. Use checkout code "FOUNDER100" the first 100 redemptions will receive 1 month free! What I'd love your feedback on: - The slop score concept — does it land for you, or is it confusing? - Anything in the extension flow that feels clunky - Channels or video types where the analysis breaks down Happy to answer any technical questions — the pipeline runs on Gemini 2.5 + Anthropic as fallback, with pgvector-based claim deduplication so we're not re-verifying the same claim across videos. Thanks for taking a look 🙏
