Turn YouTube videos and local files into timestamped reports in your language. Private BYOK mode plus optional Pro. VideoLens analyzes the video you're already watching and returns a structured, timestamped report — right in Chrome's side panel. Open a YouTube video or another page with an HTML5 video player, choose a report style, and ask what you want to learn. VideoLens samples frames, reads available captions, and creates an evidence-grounded analysis where every finding cites the exact moment in the video. Local video files work too (mp4 / webm / mov), including audio transcription for files up to 20 minutes. REPORT STYLES AND SPECIALIZED MODES • Detailed report — important ideas, context, examples, caveats, and conclusions • Key insights — signal without repetition or filler • Tutorial guide — ordered steps, commands, warnings, and verification • Interview / podcast — themes, claims, quotes, and follow-up questions • Bug report — repro steps, failure modes, severity • Meeting — decisions, commitments, follow-up actions • UX review — user friction in session replays and screen recordings • Product demo — feature inventory and positioning analysis • Content review — hook, pacing, claims, call-to-action critique • Privacy scan — find secrets, credentials, and PII before you share BRING YOUR OWN KEY — PRIVATE BY DESIGN The entire pipeline runs inside your browser. The selected video's frames, audio or captions, page title, and your prompt are sent to exactly one place: OpenAI's API, using your own API key. No VideoLens servers receive your analysis data. No VideoLens account, no extension telemetry, no extension analytics. Your key is stored only on your device. A typical video costs $0.05–$1.50 in OpenAI usage, billed straight to your own OpenAI account — estimates are shown before every run. OPEN SOURCE Free under the MIT license — unlimited analyses, no account, no product tier. ALSO IN THE BOX • Follow-up Q&A: ask more questions against the analyzed timeline for cents • Download a self-contained, professionally designed HTML report • Open the print-ready report and save a polished PDF using Chrome's print dialog • Export Markdown or JSON, or copy the report as text • Open source (MIT): github.com/shadoprizm/videolens LIMITS WORTH KNOWING DRM-protected players (Netflix, Disney+, etc.) cannot be captured — this is a browser security guarantee, not a bug. Live streams are not supported. Audio transcription of in-page videos uses available captions (YouTube); local files up to 20 minutes are transcribed directly. On other sites, cross-origin video security can prevent frame capture.
