  description

  Summarize any YouTube video in seconds — then go deeper. Bullsift extracts every key claim, fact-checks it against real sources, and flags AI-generated slop, all from a side panel while you watch.
  No more wasting 45 minutes on a video that could've been an email. No more trusting confident voices making bold claims. Paste a link or open the side panel, tap "Sift This Content," and know what's real before you share it.
  
  WHY BULLSIFT?
  Most summarizers give you bullet points. Bullsift gives you a credibility layer — so you don't just know what someone said, you know if it's true.
  
  AI Claim Extraction & Fact-Checking — Every key claim is pulled out and verified against real sources with clickable links, so you can check for yourself.
  
  Slop & Content Farm Detection — Flags recycled, low-effort, or AI-generated content with a strict Slop Score before you waste your time.
  
  Community Trust Scores — See how other users rated the video and its creator. Real votes from real skeptics.
  
  Deep Context Reasoning (Pro) — Routes claims out to the open web, cross-references multiple sources, and returns verdicts with citations.
  
  Results are cached — revisit any video and your sift is already there.
  Already used to analyze trending videos on geopolitics, AI safety, finance, and more. Join 12,000+ skeptics who think before they trust.
  
  FREE TO START
  90 sifts/month free — no credit card needed. Upgrade anytime for deep fact-checking, vision AI detection, and unlimited sifts.
  
  YOUR PRIVACY
  We only access YouTube pages — nothing else. Your data stays yours. We don't sell it, ever. Minimal permissions: just what's needed to analyze the video you're watching.

  Bullsift.ai is the AI fact-checker that lives where misinformation does — your social feeds and the videos you watch.
  
  Add a "Sift" button to YouTube, X (Twitter), Facebook, and Reddit. Click it on any video or post to get an instant credibility breakdown: a Sift Score from 0–100, AI slop detection, and claim-by-claim verdicts with linked sources you can verify yourself.
  
  ━━━━━━━━━━━━━━━━━━━━━━━━━━
  WHAT YOU GET ON EVERY POST
  ━━━━━━━━━━━━━━━━━━━━━━━━━━
  
  • Sift Score (0–100) — a single number summarizing trustworthiness
  • Sift subscores — Truth, Sourcing, Balance, Originality, Channel reputation
  • AI slop detection — flags clickbait, repetitive phrasing, AI-generated filler
  • Claim verdicts — every factual claim labeled Supported / Unsupported / Misleading / Opinion / Unverifiable
  • Cited sources — every Deep Sift verdict links to the news articles, scientific papers, or government records used to verify it
  • Summary — a one-paragraph TL;DR of what the video or post actually says
  • Vision check (videos) — frame-by-frame AI-generation detection on YouTube videos
  
  ━━━━━━━━━━━━━━━━━━━━━━━━━━
  QUICK SIFT vs DEEP SIFT
  ━━━━━━━━━━━━━━━━━━━━━━━━━━
  
  Quick Sift (free) — instant claim extraction, slop detection, and Sift Score estimate. Runs in seconds. 90 free Quick Sifts per month, no credit card.

  PRIVACY-FIRST
  ━━━━━━━━━━━━━━━━━━━━━━━━━━

  • We never read your YouTube watch history, your timeline, your DMs, or your subscriptions
  • Analysis results are cached so anyone checking the same content gets instant results — no extra cost, no extra data sent

  Don't watch it. Bullsift it.
  
  YouTube is full of confident voices making bold claims. Bullsift.ai is the credibility layer YouTube never built — an AI-powered fact-checker that instantly analyzes any video so you can think before you trust.
  
  HOW IT WORKS
  
  Navigate to any YouTube video, open the Bullsift side panel, and tap "Sift This Content." In seconds, you get:
  
  A concise summary of what the video actually says. Key claims extracted and individually fact-checked. A Slop Score flagging recycled, low-effort, or AI-generated content. Source-backed verification with links so you can check for yourself.
  
  Results are cached — revisit any video and your sift is already there.
  
  KEY FEATURES
  
  Instant Claim Sifting — AI extracts and evaluates key claims from any video
  
  Slop & Content Farm Detection — flags low-quality, recycled, or AI-generated content
  
  Interactive Transcript — timestamped and clickable, synced to the video

  AI analysis isn't perfect — that's why every claim links to its sources so you can verify what matters to you.

  The Funnel (Free) — 90 quick sifts/month. Slop and content farm detection, community trust scores. No deep fact-checking.
