## What is EvidenceLens?

Turn long YouTube videos into concise summaries—and see whether their key claims are supported by research.

Paste a YouTube link to get the main ideas and key takeaways without watching every minute. EvidenceLens can then identify factual claims, compare them with an index of more than 200 million peer-reviewed publications, and show a clear verdict with sources you can inspect.

SUMMARIZE VIDEOS AND LONG-FORM CONTENT

• Summarize YouTube videos
• Get key takeaways in plain language
• Understand web articles and PDF documents faster
• Ask follow-up questions about the source

CHECK CLAIMS AGAINST RESEARCH

• Check claims one by one: supported, refuted, mixed, or inconclusive
• Open the research behind each verdict
• See context, confidence, and important caveats
• Save useful analyses for later

MORE THAN A VIDEO SUMMARIZER

Most AI summaries tell you what a video says. EvidenceLens also helps you see what published research says about it.

EvidenceLens is useful for students, researchers, journalists, educators, and anyone who wants to learn faster without taking every online claim at face value.

EvidenceLens works best with factual and scientific topics such as health, nutrition, psychology, climate, and technology. Results depend on the source material and available research.

Important: EvidenceLens is an informational research assistant. AI-generated analysis can contain errors and is not medical, legal, or other professional advice. Check primary sources before making important decisions.

EvidenceLens is not affiliated with or endorsed by YouTube.
