Bullsift
Catch lies in YouTube videos with one click
Bullsift fact-checks any YouTube video in real time. Get an AI slop score, verified claims, channel trust scores, and sources — all without leaving the page. Stop wasting hours on misinformation. Free tier includes 90 fact-checks/month.
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 🙏
