Crickit, a real-time fact‑checking app for social media videos, launched its desktop YouTube extension in open beta in November 2025. Founded by serial Stanford StartX entrepreneur Avi Tuschman, Crickit helps people make better decisions in a media ecosystem where trust is collapsing and misinformation is surging.

Crickit overlays live fact-checks — like subtitles — so people can spot shaky claims in real time and see truth, context, and trusted sources without leaving the feed. Crickit uses AI to detect important claims in YouTube videos and then checks them against high-reliability sources from live web searches. The app labels claims using five levels of factuality, provides concise explanations with additional context, and includes ground-truth links so audiences can inspect the sources for themselves.

In testing, Crickit’s search-grounded AI engine achieved 98.7% accuracy on a product-track version of the AVeriTeC Supported/Refuted fact-checking benchmark. Based on this performance, Crickit estimates it can reduce exposure to viral misinformation by 32x in popular news videos.

“The core problem is structural, not moral. Social platforms are optimized to amplify high-arousal content, so the most outrageous and polarizing voices dominate,” said Tuschman. “With Crickit, facts can finally outrun misinformation. We trust that people can make smarter, healthier decisions when they have bite-sized, open-source intelligence streaming through their media diet.”

Crickit is non-partisan, aiming to help people make smarter, healthier decisions by turning noisy feeds into clear signals drawn from open-source intelligence. The company's software is currently focused on YouTube, with plans to expand to additional platforms in the future.
