YouTube to text
Turn a video into text in a couple of seconds — not minutes. The reason it is that fast is worth understanding, because it also explains the one case where it fails.
Two different things get called "video to text"
They produce similar-looking output and are completely different underneath. Which one a tool uses determines its speed, its cost, its accuracy, and whether it works at all on a given video.
| Reading existing captions | Speech recognition | |
|---|---|---|
| What it does | Fetches the caption track already attached to the video | Downloads the audio and transcribes it with a speech model |
| Speed | Seconds, regardless of length | Minutes; scales with duration |
| Cost | Negligible | Real compute per minute of audio |
| Accuracy | Exact on human-authored tracks | Depends on the model and the audio |
| Needs captions? | Yes — nothing to read without them | No |
This tool does the first one. That is why a 266-minute course in our testing returned its full text — 2,935 caption lines, 50,862 words — about as quickly as a three-minute one. Nothing is being transcribed; the text already exists and is being fetched and cleaned up.
The trade-off, stated plainly
Instant and free on any video that has captions. Completely unable to help on a video that has none. If a tool promises to convert any video including caption-less ones and returns results instantly, one of those two claims is not true.
Do most videos have captions?
Most videos with any real audience do. YouTube auto-generates a track for the great majority of uploads with clear speech in a supported language, and many creators add human-authored captions on top — often in several languages. Popular videos in our testing carried anywhere from 1 to 31 caption tracks.
The cases that come back empty tend to be: very short clips, videos that are pure music with no speech, uploads in languages the auto-captioner does not support well, and videos where the uploader explicitly disabled captions.
What the text looks like
Raw caption data is not readable prose. Subtitles are timed in short bursts so each one fits on screen, so the line breaks land on display boundaries rather than sentence boundaries — an 18-minute lecture arrives as 286 separate fragments.
The conversion here rejoins them into paragraphs before you see them. Where captions carry punctuation, paragraphs break at sentence ends. Where they do not — and auto-generated tracks frequently contain no punctuation at all — the break falls at the largest pause between caption lines instead, since that is nearly always where the speaker actually stopped. Without that fallback, a caption-less-punctuation video collapses into one enormous block: a music video we tested produced a single unbroken 2,089-character paragraph before this was fixed.
You also get five other views of the same text — timestamps, plain text, markdown for language models, SRT and VTT. The download page covers which to use when.
What to do with the text
- Read instead of watch. Reading a 40-minute talk takes about eight minutes, and you can skim.
- Search it. Finding the one paragraph where a topic is discussed is a text search rather than scrubbing a timeline.
- Feed it to a language model. The For AI format packages the text with the video's title, channel and source URL so the model has context. This is the most common reason people convert videos to text now.
- Quote with references. The timestamps view links every line back to its moment, so a quote can be verified in context. See timestamps.
- Translate. Clean prose translates far better than fragmented captions.
Frequently asked
How long does the conversion take?
Usually two to five seconds, and length barely matters — the text is fetched rather than transcribed.
Can it convert a video with no captions?
No. There is no text to read in that case. A tool that can handle caption-less videos has to run speech recognition, which takes minutes and costs real compute.
Is there a file size or length limit?
No. Nothing is uploaded or downloaded — only the caption track is fetched. The longest video tested was 266 minutes.
Does it work on Shorts?
Yes, when the Short has a caption track. Shorts URLs are recognised automatically.
I can see subtitles in the video — why can't they be extracted?
Because there are two different things that look identical while you watch. A caption track is text data attached to the video, which the player renders on top and you can switch off with the CC button. Burned-in subtitles are part of the picture itself — the creator added them in their editor before uploading, so they are pixels, not text. This is very common on Chinese-language channels, and bilingual subtitles shown two lines at a time are almost always burned in. To tell which you have, open the video and look at the CC button: if it is greyed out or missing, there is no caption track, and no tool can extract that text without running OCR on every frame.
Is the text accurate?
Human-authored caption tracks are essentially exact. Auto-generated ones are good on clear speech and unreliable on names and jargon. Which one was used is always shown.
