YouTube Subtitle Generator
Build timed captions from a video's audio. Free within the free quota; beyond it, a paid subscription billed by usage.
What Is a YouTube Subtitle Generator?
A YouTube subtitle generator turns the speech in a video into timed subtitles, exported as a subtitle file. It is different from a transcript: the transcript is plain text you read and search, while a subtitle file pairs every line with the moment it is spoken so a player can display it. The platform only shows captions when the creator already added them, and automatic captions are often mis-timed or wrong on names and accents. A real generator starts from the audio instead, aligning each timestamp to the spoken words so captions track speech correctly, and it transcribes any video that was never captioned. Whether you search for an auto subtitle generator, a caption generator, or an SRT generator, the result should be a caption file you can actually import.
How the YouTube Subtitle Generator Works
One pasted link turns a video into timed subtitles, with file downloads and nothing to install.
Turn a Video Link Into Subtitles
Paste a video link into the YouTube subtitle generator. It first checks whether the video already has a caption track, since an existing track is the most accurate source, and then transcribes the spoken audio with AI when there is none. Either way you get timed lines, each with its own in and out point, so the captions can be displayed as the video plays. Because the timing is generated from the speech rather than averaged across a block of text, the subtitles stay in sync from the opening line to the end of a long video, and the file is complete rather than a sample of the opening.
- Works from a pasted link, with no download step
- Transcribes videos that have no captions
- Each line carries its own in and out time
Read and Check Each Line
Read the subtitle lines on the page, with the timestamp beside each one, and check the wording against what was actually said. Search for a term, jump to that moment in the video, and fix a name or a phrase before you download anything. Catching a misheard word here is far cheaper than finding it after the captions have been burned into a finished edit or uploaded to a platform. If you would rather start from finished text, the YouTube transcript page gives you a full written version to time the subtitles against.
- Read each caption beside its timestamp
- Search the full text to check a line
- Fix wording before exporting
Download the Subtitle File
The track is timed once; download it as SRT for editors and social platforms, or as VTT for the web. Translate it into another supported language while the timings stay in place to produce a second caption file, or keep the plain text for notes and descriptions. One generated track can become a caption file for your own edit, a translated version for a new audience, and a readable record for search engines, all from the same pasted link. The download keeps the line breaks you reviewed, so the file matches what you saw on screen.
- SRT and VTT download in one step
- Translate and keep the timings
- Keep the plain text too
Why Transcript Beats Automatic Captions
✅ YouTube subtitle generator
Paste any public link and get timed captions you can read, correct, and download as a subtitle file. The timing comes from the speech itself, so the subtitles stay in sync, and a translated version keeps the same timings. Nothing is written back to the original video, so correcting a line only changes your own file.
❌ Automatic captions
They appear only when the creator enabled them, they mis-time longer blocks, and they mishear names and accents. There is no download button, no way to fix a line in bulk, and nothing at all for an uncaptioned video. There is also no way to translate what the panel shows, which leaves a second language out of reach.
Who Needs a YouTube Subtitle Generator
Anyone who needs timed captions on a video they did not caption themselves gets more from it.
For Video Editors and Creators
An editable file from a YouTube subtitle generator is faster than typing subtitles by hand, especially on a long video with several speakers.
- Import the SRT file into your editor and adjust names and line breaks instead of typing every caption.
- Caption a video you did not script without transcribing it yourself.
- Fix timing once rather than re-syncing every block by hand.
- Keep captions on-brand by editing the wording before export.
- Reuse the track across platforms that expect the same file.
- Standardise line length before export so captions read evenly across the screen.
For Translators and Localisation Teams
A timed source file is the starting point for every translated version of a video. The track is timed once, so every translated version reuses that work.
- Translate with timings preserved so the new track drops straight in.
- Start from accurate timing instead of re-timing a machine-translated block.
- Check names and acronyms against the text before translating.
- Produce several language tracks from one generated file.
- Hand a clean source to a reviewer without extra formatting work.
For Educators and Course Creators
Captioned lessons are easier to follow, easier to translate, and easier to search. One paste produces a track rather than a captioning session, because the lesson already exists as a recording.
- Caption a recorded lecture so students can read along.
- Translate a lesson for a class in another language.
- Provide plain text alongside the captions for revision.
- Fix technical terms before students see them.
- Reuse the captions for a flipped-classroom version of the same lesson.
For Social Media Managers
Captions decide how far a clip travels, and a neat file makes the difference between readable and rejected.
- Caption a clip in the platform's expected format.
- Translate a campaign so the same video runs in several markets.
- Check a line before publishing against the plain text.
- Keep one source file for every platform that accepts SRT subtitles.
- Avoid re-uploading because a caption was mistyped.
- Check the wording once and reuse it in the post copy.
For NotebookLM and AI Power Users
Captions and plain text are the layer AI tools read best, and one generated file serves both. They come from the same run, so you do not pay twice in time for the same words.
- Google NotebookLM: add the plain text as a source to summarise the video.
- ChatGPT, Claude, Gemini, Kimi, and Manus: use the text for summaries, notes, or translations.
- Build a searchable archive by keeping the plain text.
- Translate or reformat the text for a different audience.
- Feed an agent or an API with the text for the rest of your pipeline.
How to Generate YouTube Subtitles From a Link
- 1
Paste the Video Link
Copy any public video URL and paste it into the box at the top of the page. There is no download and no software to install: the link is all the input needed.
- 2
Generate the Timed Captions
Start it: the creator's caption track is read when one exists, and the speech is transcribed with AI when it does not. You get a timed track, every line with its own timing. Paste a second link without leaving the page.
- 3
Read and Check the Timing
Read the lines beside their timestamps and search the text for any word you want to verify. Fix a name or a phrase before you export, so the caption file is correct the first time it is imported. Reading before exporting is what keeps a wrong word out of a finished upload.
- 4
Download the YouTube Subtitles
Download the track as SRT subtitles or a VTT file, or translate it into another supported language with its timings kept. The same file works in an editor, a web player, or a platform upload.
Use the Subtitles in the Apps You Already Have
Google NotebookLM
Add the text behind the captions as a notebook source to summarise the video and ask questions about it. That text is exactly what NotebookLM can read.
ChatGPT, Claude, Gemini, Kimi, and Manus
Paste the text into the assistant you already use to tighten the wording, shorten long lines, or start a translation.
Video Editors and Subtitle Tools
Import the exported file straight into your editor, player, or hosting platform. The timing is already in place, so the captions land on the timeline without hand-adjusting every line.
Builders Using the API and MCP
An API and an MCP server are also available, so a script or an agent can produce subtitles and pass the file into the rest of your pipeline.

YouTube Subtitle Generator FAQs
What is a YouTube subtitle generator?
A YouTube subtitle generator turns the speech in a video into subtitles you can download as an SRT or VTT file. Each line carries its own in and out time, so a player or editor can display it in sync with the video.
How do I generate YouTube subtitles from a video link?
Paste the video URL into the YouTube subtitle generator. The existing caption track is used when there is one, or the audio is transcribed with AI when there is not, and you get subtitles you can download.
Can the YouTube subtitle generator create subtitles when a video has no captions?
Yes. When a video has no caption track, the speech is transcribed with AI instead, so you still get a full subtitle file rather than nothing to download.
Does the YouTube subtitle generator export SRT and VTT?
Yes. You get an SRT file for editors and social platforms, and a VTT file for the web. Both formats keep the same timings, so the same captions work in either place.
Is this YouTube subtitle generator free?
Paste a public link and the subtitles appear in the browser, with no extension to add. Free use covers the free quota; beyond it you need a paid subscription, billed by usage.
Is this an auto subtitle generator?
Yes. The YouTube subtitle generator times every line from the speech on its own, so you paste a link and get subtitles without typing or syncing anything by hand.
Does it work as a caption generator too?
Yes. Captions and subtitles are the same timed track, so here they are one step: paste the link and download the caption file.
How is this different from automatic captions on YouTube?
Automatic captions appear only when the creator enabled them and offer no download, while this page works on any public video and lets you check, correct, and download the captions as a file.
Can I translate the subtitles into another language?
Yes. The track can be translated into another supported language with its timings kept, so the translated captions line up with the video exactly like the original.
How accurate is the YouTube subtitle generator?
Accuracy depends on the source. Creator captions are usually precise, while AI transcription can mishear names, accented speech, or overlapping voices. You can correct any line on the page before exporting the file.
Can I edit the subtitles before downloading them?
Yes. The lines are shown as text beside their timestamps, so you can read them, check the wording against the video, and fix a name or phrase before you download the subtitle file.
Can I use the YouTube subtitle generator for a video I did not create?
Yes. Any public video works, so you can caption your own uploads or someone else's.
Does it include a transcript as well?
Yes. A plain-text transcript comes with the timed captions in the same run, which is useful for descriptions, notes, and search, while the subtitle file is what you import into a player or editor.
Can I get subtitles for a YouTube live stream?
A live stream becomes captioned once it has ended and a recording exists. An in-progress stream is not available yet, because there is no finished audio track to time.
What is the difference between subtitles and a transcript?
A subtitle file pairs each line with its timing so a player can display it, while a transcript is the plain readable text of what was said. Both come from the same link here.
Can I generate YouTube subtitles in bulk?
It works on one pasted link per run, which keeps the timing and the wording reviewable. For a whole series, use the YouTube playlist transcript page, which queues every video and returns the text together.
What timing does the generated subtitle file use?
Each line is timed against the spoken words in the video, so the captions follow speech rather than sitting on screen for a fixed interval. That is what keeps a translated track aligned with the original.
