Two Ways to Summarize a Video
Paste a URL
Paste a YouTube, Google Drive, or any public video link. VexaScribe fetches and processes the audio directly. Get a summary in minutes with no file download needed.
Upload a File
MP4, MOV, M4A, WAV, MP3 up to 5 GB. Upload recorded Zoom calls, lecture videos, podcast files, or any local video you can't share via a public URL.
File upload is the only path for private content, recorded meetings, and files not on a public URL.
How It Works — 3 Steps
Upload or Paste URL
Drag-and-drop a video or audio file, or paste a YouTube URL. Supported: MP4, MOV, MP3, WAV, M4A, FLAC — up to 5 GB.
AI Transcribes and Summarizes
Whisper Large-v3 transcribes the audio. The AI then generates a structured summary with key points, action items, and chapter markers. A 1-hour video takes 6–12 minutes total.
Export the Summary
Download the summary as TXT or DOCX. The full transcript is also available alongside it — export as TXT, DOCX, or SRT.
What People Use It For
Recorded Meetings
Upload your Zoom, Teams, or Google Meet recording. Get action items, decisions, and a summary ready to share — without a bot in the call.
Lecture Videos
Summarize a 1-hour lecture into structured notes with timestamps. Jump to the exact moment a concept was introduced.
YouTube Videos
Paste any public YouTube URL. Get the key points without watching the full video — useful for research and quick triage.
Podcast Episodes
Upload MP3 or M4A. Get a summary with key topics and notable quotes — useful for show notes or research.

When to Use a Different Tool
If you only need to summarize public YouTube videos and want zero signup, tools like Eightify or NoteGPT offer instant browser-extension or URL-paste summaries with no account required. VexaScribe is the better choice when: you have a file (not a public URL), you need structured action items and chapter markers rather than bullet points, you need multilingual support, or you want the full transcript alongside the summary.
Video Summarizer FAQ
How do I summarize a video without watching it?
Upload the file or paste a YouTube URL to VexaScribe. The AI transcribes the audio track, then generates a structured summary with key points and timestamps — you get the gist of a 1-hour video in under 2 minutes of reading. No manual skimming required.
Can I summarize a Zoom recording?
Yes. Export the recording from Zoom as MP4 (local recording) or download from Zoom Cloud, then upload to VexaScribe. You get a summary with action items, decisions, and key quotes — the same structured output as the meeting bot, without a bot joining the call.
What's the difference between a transcript and a summary?
A transcript is the full verbatim text — every word spoken, with speaker labels and timestamps. A summary distills the key points: main topics, decisions, action items, notable quotes. VexaScribe generates both — the transcript is always available alongside the summary so you can verify any point.
How long does it take to summarize a 1-hour video?
About 6–12 minutes total: 5–10 minutes to transcribe the audio, then under 30 seconds to generate the summary. You can close the browser while it processes — the result is saved to your account.
Does it work for non-English videos?
Yes. VexaScribe supports 99 languages using Whisper Large-v3. Language is auto-detected from the audio. Summaries are generated in the same language as the video. Mixed-language (code-switching) audio is handled, though accuracy is lower on rapid switches.
What does the summary output look like?
A structured document with: a 2–3 sentence overview, 5–10 key points each with a timestamp, extracted action items (task / owner / deadline fields), chapter markers dividing the video into sections, and notable quotes. The structure adapts by content type — meeting recordings emphasize decisions and action items; lectures emphasize concept hierarchy.
Can I summarize a lecture recording?
Yes. Upload the lecture video or audio file (MP4, MOV, M4A, WAV, MP3 — up to 5 GB). VexaScribe transcribes the lecture and generates a summary organized by concept, with timestamps so you can jump to specific sections. Export as TXT or DOCX for use in study notes.
What file formats does the video summarizer accept?
Video: MP4, MOV, WEBM, AVI, MKV. Audio: MP3, WAV, M4A, FLAC, OGG, AAC. Maximum file size 5 GB — equivalent to about 5–6 hours of standard MP4 video. YouTube URLs are also accepted directly.
