Cut a text into valid subtitle cues

Video makers and trainers can use it when ordinary text must become clean WebVTT cues before a recording is released.

Cut a text into valid subtitle cues. The result stays in your browser, ready to review, copy and adapt without an account or any transfer of your input.

How to use

Set how many seconds you want each subtitle block to last on the first line.
Keep the separator line in the input field between that duration and your text.
Paste the written text you want to split, using clear punctuation and complete sentences.
Run generate to create valid WebVTT cue blocks in the correct order.
Review the cues and fix any break that feels too short, too long or awkward.

Example

With four seconds per block, paste a short spoken introduction. The tool splits the text into ordered cues and displays WebVTT blocks. Check the breaks carefully so each line remains easy to read while the video plays, then load the file in your player.

Limits and formats

It does not listen to audio or sync cues with a soundtrack.
Every block uses the same duration, which may not suit all speech patterns.
Missing or irregular punctuation can create odd splits and very short cues.
The finished file should be tested in the player or platform you use.
Very long texts can produce many cues, so allow time for proofreading.

Where processing happens

The splitting runs inside your browser. Your pasted text and chosen duration stay on your device, with no outside transfer. The resulting cues are shown directly on the page, ready to review and copy.

Frequently asked questions

Can I use a text that was already transcribed?

Yes. This tool expects written text. Paste the transcript, add sensible punctuation and run generate. You will get a WebVTT starting point that still needs a human review before release, because the tool does not fix wording or timing errors.

Why are some cues split in the middle of a sentence?

The tool follows the duration you set and the amount of text. A long sentence may spread across several cues. Try a different duration or rewrite the sentence so the split lands at a more natural pause.

Will the result work in every video player?

WebVTT is widely supported on the web, but players can differ in how strictly they read it. Always load the file in your own player or publishing platform to confirm the subtitles appear correctly. If not, check the cue order and timing.
