The problem
Subtitling a video shouldn't cost by the minute
Look for an automatic subtitle tool and you mostly find upload queues, credit meters and watermarked exports.
Upload first, wait later
Online caption sites want your whole video on their servers, then make you wait in a queue for the result.
Paid by the minute
Free minutes run out after one clip. A long lecture or a series of episodes quickly turns into a bill.
Another monthly plan
Translation, burned-in captions and longer videos are usually locked behind a subscription that renews every month.
Watermarks on the export
Free tiers stamp a logo on the finished video, or cap the resolution, right when you need it to look professional.
Hours of manual timing
Typing and syncing every line by hand takes far longer than the video itself, and one slip throws everything out.
Translation is a separate job
Paste lines into a translator one by one, then fix the timing again. Doing three languages means doing it three times.
Vow Auto Subtitle Generator and Translator fixes all of it.
How it works
Drop. Translate. Done.
Three choices, one button, and timed subtitles appear beside your video, ready for any player.
- 01
Drop your video
Drag in a video or audio file, a whole folder, or a subtitle file to translate. MP4, MKV, MOV, MP3, WAV and more, any length.
Drop a video or audio file and choose languages and format - 02
Pick the languages
The spoken language is detected by itself. Add the languages you want it translated into, and choose SRT, WebVTT, ASS or more.
...and the quick guide with what the app does for you - 03
Create, check, share
Press Create subtitles. Movie.en.srt and Movie.es.srt land beside the video, and the editor opens with the video, the lines and a timeline.
Open subtitles to check, fix, restyle and translate them
Features
A subtitle studio that lives on your PC
For creators, teachers, translators and anyone who wants their videos understood, in their own language or someone else's.
Whisper AI that really listens
Whisper speech recognition, Large v3 Turbo by default, hears 99 languages and detects the spoken one by itself.
Translate into 115 languages
Offline on your PC, keeping every subtitle's timing. Several languages at once, bilingual files, a glossary and formal or informal tone.
Timed to the word
Every word gets its own time and lines are cut at natural pauses within reading rules, with presets for broadcast, short videos and word by word.
A real subtitle editor
The video with the subtitle on it, the list beside its translation and a waveform timeline: drag to retime, split, merge, find and replace, undo.
Burn-in styles
Classic, Cinema, Boxed, Yellow, Social, Neon or Minimal, or your own font, colours and box, with karaoke-style word highlighting.
Videos with subtitles
Burn subtitles into a copy of the video, encoded on your graphics card, or add switchable subtitle tracks to MP4 and MKV without re-encoding.
Every subtitle format
Saves SRT, WebVTT, ASS, SBV, TTML, MicroDVD, LRC, text, JSON and CSV, and opens all of them for translation or editing.
Fast on your graphics card
Runs on NVIDIA, AMD or Intel graphics through Vulkan, or on the processor. Voice detection skips silence and music so nothing is invented.
Private by design
Listening and offline translation happen on your PC. Your videos are never uploaded, and online translators are only used if you choose one.
Light and dark theme
Switch between a bright paper look and a dark carbon look with one click in the sidebar, or let it follow Windows.
Light & dark theme
Easy on the eyes, day or night.
Subtitle Generator comes with a crisp light theme and a calm dark theme. Switch with one click, or let it follow your Windows setting by itself. It remembers your choice.
- LightClear and bright for daytime and busy offices
- DarkGentle on tired eyes late at night
- Follow WindowsChanges by itself when your PC does

Automatic, translated subtitles in a few minutes, without uploading the video anywhere.
Step 1: get it freeInstall it free
Download Vow Auto Subtitle Generator and Translator from this page and run the installer. It needs no administrator rights and no account. The speech model downloads once with your first video.

Accurate is the recommended setting; Fast and Max are one click away. The subtitles are written beside the video as Movie.en.srt, Movie.es.srt and so on.
Check them in the editor
Press Edit to see the subtitles on the video, read the translation beside each line and drag blocks on the timeline to adjust. Then burn them into a copy, or just play the video in any player.

FAQ
Questions about Subtitle Generator
Is Vow Auto Subtitle Generator and Translator free?
Yes. You can subtitle or translate 5 videos every day for free, with every speech model, every language and every format, the full editor, styles and videos with burned-in subtitles. There are no ads and no watermarks. Unlimited, a one-time $9.95 USD payment, removes the daily limit and lets you do whole folders and series in one go.
Does it upload my videos?
No. Speech recognition and offline translation run on your own PC, on the graphics card or the processor. The AI models download once on first use; after that subtitles work with no internet. Online translators such as DeepL or Google are only used if you choose them in Settings.
Which languages does it understand and translate?
It recognises 99 spoken languages and detects which one is spoken by itself. It translates subtitles into 115 languages, several at once, keeping each subtitle's timing.
Which subtitle formats can it make?
SRT, WebVTT, ASS, SBV, TTML / DFXP, MicroDVD SUB, LRC, plain text, JSON with every word, and CSV. It can also open all of them except plain text, to translate or edit existing subtitles.
Can it burn subtitles into the video?
Yes. Make a copy of the video with the subtitles burned in, in one of the ready styles or your own font, colours, outline and box, with optional word-by-word highlighting. Or add switchable subtitle tracks to MP4 and MKV without re-encoding.
How fast is it?
On a fast graphics card it works many times faster than real time: the developer measured a 1-hour recording in about 50 seconds on an RTX 5090. It also runs on NVIDIA, AMD and Intel graphics or on the processor alone, more slowly.
Can I subtitle a video from a link?
Yes, for videos you own or have the right to download. Paste a YouTube or other video link and it fetches just the sound to subtitle, or the video too when you burn subtitles in.
Is it safe to install?
Yes. It is made and published by XTO Pty Ltd, an Australian company. The installer contains no ads, no toolbars and no bundled software, needs no administrator rights, and uninstalls cleanly from Windows Settings.
