Record a Video in Chrome, Get an AI Summary
This Chrome extension records screen, window, browser tab, microphone and camera, with system audio, so it captures whatever is playing, YouTube, Vimeo, an online course, or a video call, and sends the recording to your ScreenApp library. There, the AI transcribes it and writes a summary with chapters, so you get the key points instead of watching the whole thing.
If you already have a YouTube or Vimeo link and don’t need the extension, paste it into the YouTube video summarizer or the AI video summarizer, which do the same job without recording anything live.
What you get:
- A transcript with timestamps, in 100+ languages
- AI notes: a summary and the main points
- chapters with timestamps
- AI chat with any recording
- Export as PDF, DOCX, TXT, SRT and VTT
- Free plan: 2 transcriptions of recordings up to 45 minutes each, with AI chat on it
How to Summarize a Video with the Extension
- Install the extension: Add ScreenApp from the Chrome Web Store. The icon sits in your toolbar.
- Record the tab: Open the video and click the extension icon to start recording the tab. Let it play through, or stop early if you only need part of it.
- Read the summary: Stop the recording and the transcript, AI summary, and chapters are ready in your ScreenApp library a few minutes later. Ask AI a question about the video and get an answer that points to the moment.
Accuracy depends on the audio. Clear speech with captions or clean narration transcribes better than a noisy recording with music over the dialogue. See how we measure accuracy.

Who Uses a Video Summarizer Extension
Students record lecture recordings and course videos playing in the browser, then read the AI summary and chapters instead of rewatching the whole session before an exam.
Professionals record webinar replays and training videos to get the main points before deciding whether the full recording is worth watching.
Researchers record interviews, conference talks, and educational videos played back in a tab, then search the transcript instead of relistening.
Content creators record videos from other channels for reference, then pull quotes and structure notes from the transcript.
Remote and part-time learners build up a library of recorded course videos and webinars they can search across a whole term.
