Why VidSense

Everything a video says and shows,
ready when you need it.

Transcripts you can trust

Accurate, timestamped transcripts of any video file or YouTube link. VidSense learns the brand names and jargon in your content, so terms come out spelled right.

  • Click any line to jump to that moment
  • Search every word, instantly
  • PDF, text and subtitle downloads

See what’s on screen

Slides, charts and demos carry half the lesson. VidSense looks at the video itself and describes what appears, so the visual details make it into your notes too.

  • Frame-by-frame descriptions
  • Slides and on-screen text captured
  • A tidy “What’s on Screen” PDF

Answers, not just text

Get a summary, chapters and key insights for every video, then ask follow-up questions in plain English. Each answer points to the exact moment it came from.

  • Summaries, chapters and key topics
  • Chat with any video
  • Takeaways and next steps

How it works

From video to understanding in three steps.

  1. 1

    Add a video

    Drop in a video file, a whole folder, or paste a YouTube link.

  2. 2

    VidSense does the listening

    It transcribes on your own device, reads the screen, and builds a summary and chapters.

  3. 3

    Find what matters

    Search, ask questions, jump to moments, and download clean PDFs to keep.

Private by design

Your videos stay yours.

VidSense does its heaviest work inside your browser, so your recordings are never uploaded to us.

  • Transcribed on your device. Speech recognition runs locally, even for hour-long lectures.
  • Your library, your account. Finished transcripts sync to your account so they’re on every device you use.
  • Your own AI key. AI features send only the transcript (and, for What’s on Screen, a set of still frames) to Claude on your own Anthropic account. Your key stays in your browser.

Questions

Good to know

Is VidSense free?

Yes. Creating an account and transcribing are free. AI features such as summaries, chat and What’s on Screen use your own Claude API key, so any AI usage is billed to your Anthropic account, usually well under a dollar per video.

How do I sign up?

Click Create your free account and continue with Google, or enter your email to get a one-time sign-in code. There’s no password to remember.

Which videos work?

MP4, MOV, WebM, MKV, MP3 and M4A files, including very long ones, plus any YouTube video that has captions. Chrome and Edge on a recent computer are fastest.

What languages are supported?

VidSense is tuned for English, which gives the best accuracy.

Can I use it on my phone?

You can browse your library, read transcripts and chat on a phone. Transcribing long videos works best on a laptop or desktop.
