Summarize a YouTube Video Without Captions
No captions, no transcript, no subtitles — no problem. RunCLI transcribes the audio with AI and summarizes it in one step.
Claude AI + Deepgram speech-to-text — automatic fallback when captions are missing
Extract existing captions as text, AI-transcribe uncaptioned audio, or summarize any text you already have. YouTube Summary, YouTube Transcript and AI Summarizer
Automatic AI Transcription
When captions are missing, RunCLI transcribes the audio with Deepgram speech recognition — you don't change a thing.
No 'Transcript Unavailable' Errors
Most summarizers stop at the missing-captions error. RunCLI keeps going and returns a summary anyway.
Same Structured Output
Key points, timestamps, and core takeaways — identical format whether the video had captions or not.
Up to 5 Hours
The AI transcription path handles videos up to 5 hours long, billed at 2 credits per minute.
How It Works
Paste the URL
Any YouTube link works — you don't need to check whether the video has captions first.
RunCLI picks the path
Captions found? They're summarized directly. No captions? The audio is transcribed with AI first, automatically.

Use Cases
Live stream replays
Stream archives often publish without captions. RunCLI transcribes and summarizes them anyway.
Small-channel uploads
Auto-captions don't always exist on niche or brand-new videos. Get a summary regardless.
Caption-disabled videos
Some creators turn captions off entirely. RunCLI doesn't depend on them.
Podcasts and interviews
Long conversational episodes uploaded without subtitles get the same key-points treatment.
Non-English videos
Videos in languages YouTube skipped for auto-captions can still be transcribed and summarized.

Frequently Asked Questions
How do I summarize a YouTube video that has no captions?
Paste the URL into RunCLI like any other video. If no captions are found, the audio is automatically transcribed with AI speech recognition and then summarized. There's no separate mode to pick.
Why do other summarizers fail on videos without captions?
Most tools only read YouTube's caption track and have no transcription engine behind it. When the track is missing, they return an error like 'transcript unavailable.' RunCLI transcribes the audio itself instead.
Does the no-captions path cost more?
Yes. AI transcription is billed at 2 credits per minute of video instead of the flat 3 credits — a 10-minute uncaptioned video costs 20 credits. Still pay-as-you-go, no subscription.
How long can an uncaptioned video be?
Up to 5 hours on the AI transcription path. Captioned videos skip transcription and have no strict length limit.
Does it handle non-English videos without captions?
Yes. The speech recognition engine supports 100+ languages, so uncaptioned videos in other languages transcribe and summarize fine.
Will I notice when the fallback kicks in?
The flow looks the same — paste, run, read. The differences are processing time (transcription takes a bit longer) and per-minute billing instead of the flat rate.
Is it free to try?
Yes — free to try, no sign-up needed to start. Signing up with Google adds free credits, and there's no subscription after that.
Can I get just the transcript instead of a summary?
Yes. YouTube Transcriber (2 credits/min) transcribes uncaptioned videos with speaker labels, and YouTube Transcript extracts existing captions as clean text.
