About this app

Turn long YouTube videos into clear summaries—then check the claims that matter against published research.

EvidenceLens combines an AI video summarizer with research-backed fact checking. Paste a YouTube link, share a web article, or open a PDF to see the key takeaways, important factual claims, and evidence you can inspect.

SUMMARIZE VIDEOS AND LONG-FORM CONTENT

• Get a concise overview of a YouTube video
• Find the main ideas and key takeaways
• Understand web articles and PDFs faster
• Ask follow-up questions about the source

CHECK CLAIMS AGAINST RESEARCH

EvidenceLens identifies factual claims and compares them with an index of more than 200 million peer-reviewed publications. Each claim can be marked supported, refuted, mixed, or inconclusive, with context, confidence, caveats, and cited papers.

USE EVIDENCELENS TO

• Decide whether a long video is worth your time
• Review the evidence behind health, nutrition, psychology, climate, and technology claims
• Save useful analyses and return to them later
• Get an evidence-based second opinion for study, research, journalism, or everyday learning

HOW IT WORKS

1. Paste or share a YouTube video, article, or PDF.
2. Read the summary and key takeaways.
3. Explore claim-by-claim verdicts.
4. Open cited research and ask follow-up questions.

EvidenceLens works best with factual and scientific topics. Results depend on the available source material and research.
