The direct answer
What VideoLens does
Transcript-only YouTube summaries can miss slides, demonstrations, code, charts, captions, and silent changes. VideoLens adds frame-level vision and OCR before it writes the report.
Choose Detailed Report, Key Insights, Tutorial Guide, or Interview / Podcast. Then read it in the app, ask follow-up questions, or export a polished standalone document.
Why it helps
From linear video to reviewable evidence
Clickable evidence
Use timestamps to jump back to the relevant part of the original video.
Professional artifact
Open or share a polished standalone HTML report and print the same design as a PDF.
Workflow
How the analysis works
Every stage is explicit and cached so the source can be checked and the analysis can be reused.
Paste an accessible YouTube URL into the hosted app, CLI, or supported extension workflow.
Choose a report style and optionally refine the prompt.
VideoLens retrieves the media, transcribes audio, samples frames, and merges the evidence by time.
Review, question, and export the resulting report.
Output
What the report gives you
- Executive summary and key findings

Important limitation: Availability depends on the source and yt-dlp support. Private, age-gated, region-restricted, removed, live, or DRM-protected content may not be accessible. Respect the rights and terms that apply to the source video.
FAQ
Common questions
Is VideoLens just a YouTube transcript summarizer?
No. It combines transcription with sampled-frame descriptions and OCR, which helps when meaning is carried by slides, interfaces, demonstrations, or visible text.
Can I ask questions about a long YouTube video?
Yes, within the practical context and cost limits of the pipeline. Sampling, audio chunking, and caching are designed to make longer sources manageable.
Can I export the result?
Yes. VideoLens creates a branded standalone HTML report and matching print-quality PDF, plus Markdown and JSON. Follow-up answers can reuse the cached timeline.
