EvidenceLens — AI Summaries for YouTube™ & Claim Checks

AI summaries for YouTube™ videos, with key takeaways, research-backed claim checks, and cited Q&A.

EvidenceLens is an AI video summarizer for YouTube that adds research-based fact checking. It creates a clear summary and key takeaways from the transcript, and you can then check important claims against a research index of 100M+ scholarly works. After installation, go to a YouTube watch page that has an available transcript. EvidenceLens sits beside the video, where you can read a summary, check claims and ask follow-up questions. • Video summaries: main ideas, structure, and key takeaways. • Claim checks: see what research supports, disputes, or leaves uncertain, with cited papers. • Ask questions: get transcript-grounded answers with source context. EvidenceLens works directly on YouTube watch pages and supports 12 languages plus light and dark themes. AI results can be incomplete or wrong, so review the cited sources before relying on them.
