What this subtitle generator does
Automatic speech recognition
When the speech model is available, it runs locally to create timed subtitle lines. Model download, browser support and device resources affect availability. You can also import SRT or VTT files.
Nothing is uploaded
Audio decoding and speech recognition happen on your device. Your video, audio, and words never reach a server.
Edit every line
Fix wording, adjust start and end times, add or delete lines before you export anything.
SRT and VTT export
Download SRT/VTT subtitle files or export MP4 with styled subtitles in a supported browser.
Subtitles without uploading your footage
This tool processes your media locally in your browser. Your source files are not uploaded to DojoClip. Keep the tab open while processing and save the result before leaving.
From speech to clean subtitle lines
Raw speech recognition produces long, unbroken passages. This tool splits them into readable caption lines, limiting length and duration, splitting at sentence boundaries, and using CJK-aware line breaks for Chinese, Japanese, and Korean.
Works with the rest of your workflow
Trim the video first with the free video trimmer, or pull the soundtrack out with the audio extractor if you only need the audio transcribed. Once your subtitles are ready, add a logo or blur with the video watermark tool. And if you want styled captions with word highlights, automatic translation, or chat-based editing, Video Edit AI picks up where this free tool ends.
FAQ
Is this subtitle generator really free?
Yes. This tool is free, with no account or added DojoClip watermark. Processing happens on your device; browser support and available memory still limit the files you can use.
Is my video uploaded anywhere?
No. The audio is decoded and transcribed locally on your device. Nothing is sent to DojoClip — which matters for unreleased or confidential footage.
Which languages are supported?
The model understands 90+ languages, including English, Spanish, French, German, Italian, Portuguese, Korean, Chinese, and Japanese. Use auto-detect or pick the spoken language for best results.
How accurate are the subtitles?
Clear speech transcribes very well. Heavy accents, background music, or crosstalk will need a few manual fixes — that is exactly what the built-in editor is for.
Can I burn the subtitles into the video?
Yes. Choose a video, generate or import subtitles, select a style and choose Export MP4. The captions become part of the video image. MP4 export requires browser encoding support; use a current Chrome or Edge. You can also download SRT/VTT separately.
Why is it slower on my machine?
Speed depends on your device, browser, available acceleration and the selected speech model. The first run also needs a model download. Long files use more memory; there is no fixed speed guarantee.
