Frequently Asked Questions
What does the YouTube Summarizer do?
Extracts captions from any YouTube video and uses AI to create a structured summary with clickable timestamps. Choose Key Points, Detailed, or Action Items mode.
Is it free?
Yes! Free users get 3 summaries per day. All modes are free, no signup required.
What video lengths are supported?
Videos up to 2 hours long. Longer videos may have their transcript truncated, but the AI still summarizes the available content.
What if a video has no captions?
The tool requires captions (auto-generated or manual). Most YouTube videos have auto-generated captions. Videos without any captions cannot be summarized.
Can I summarize non-English videos?
Yes, if the video has captions in any language. The AI will summarize in English. For best results, videos with English captions work best.
How accurate are the summaries?
The AI preserves key points and arguments from the transcript. We recommend checking the original video for critical details, as with any AI summary.
What are the clickable timestamps?
Each timestamp links directly to that moment in the YouTube video. Click [2:30] and the video opens at 2 minutes 30 seconds.
Can I download the full transcript?
Yes, expand the transcript section below the summary and use the Copy button. You can also download the summary as a .txt file.
How does this compare to tools like Summarize.tech or NoteGPT?
Similar concept, but we offer three summary modes (Key Points, Detailed, Action Items) plus a full clickable transcript with timestamps. No login wall — just paste and go. Free tier gives 3 summaries per day.
Can I summarize a podcast or audio file instead of a YouTube video?
This tool requires a YouTube URL with captions. For audio files (MP3, WAV, etc.), use our <a href="/ai/video/audio-to-text">Audio to Text</a> tool to get a timestamped transcript, then paste it into the <a href="/ai/summarizer">AI Summarizer</a> for a summary.
Does it work on mobile?
Yes. Paste a YouTube URL on your phone, pick a mode, and get your summary. The timestamps link directly to the YouTube app or mobile browser at the exact moment.
Can I share the summary with someone?
Yes. Use the Share button to copy a link, share on X (Twitter), or send via WhatsApp. You can also download the summary as a .txt file or copy the full text to paste anywhere.
What if the summary misses something important?
Expand the full transcript below the summary to read the original captions. You can also switch to Detailed mode for a more thorough section-by-section breakdown. For deep analysis of the content, try pasting the transcript into our <a href="/ai/rewriter">AI Rewriter</a> to restructure it.
Coda One's YouTube Summarizer extracts captions from any YouTube video and uses AI to generate structured summaries with clickable timestamps.
