About Bullsift
The credibility layer for YouTube. AI-powered fact-checking, deepfake detection, and community trust scoring — so you can think before you trust.
Our Mission
YouTube is the world's largest video platform, with over 500 hours of content uploaded every minute. Mixed in with legitimate journalism, education, and entertainment is a growing flood of misinformation, AI-generated slop, and manipulated media designed to mislead.
Bullsift exists to give every viewer a defense layer. We built a multi-model AI pipeline that can extract claims from any YouTube video, verify them against real sources, detect AI-generated and deepfake content, and produce a transparent credibility score — all in seconds.
We believe credibility shouldn't be gatekept. Our free tier gives everyone access to instant content analysis. Our paid tiers add deep web-verified fact-checking and community trust voting, where real users hold creators accountable.
What Bullsift Does
Instant AI Summaries
Paste any YouTube URL and get an AI-generated summary, extracted claims, and a Slop Score that flags clickbait, speculation, and low-quality content — before you watch.
Deep Fact-Checking
Our Deep Sift engine routes verifiable claims to the open web, cross-references multiple sources, and returns concrete verdicts with clickable citations you can verify yourself.
Deepfake Detection
Vision AI analyzes video frames to detect AI-generated imagery, face swaps, synthetic media, and faceless content-farm patterns that signal low-quality automated production.
Community Trust Engine
Paid members vote on claims, flag misinformation, and override AI verdicts. Community votes train Baseline Trust Scores for every creator, building a crowd-sourced accountability layer.
How It Works
Bullsift uses a multi-pass AI pipeline. Pass 1 (Quick Sift) extracts the transcript, generates a summary, identifies individual claims, and calculates a deterministic Slop Score using 10 weighted factors including clickbait detection, speculation ratio, and content-farm heuristics.
Pass 2 (Deep Sift) takes the most critical verifiable claims and routes them to web search engines. The AI cross-references multiple independent sources and returns one of seven verdict categories — from Supported to Misleading — each with reasoning and clickable source citations.
Every analysis also generates trust scores that blend AI assessment with community voting. As more users vote, community consensus gradually gains weight against the AI score, creating a self-correcting credibility system.
