Subtitles & translation for your videos — in minutes, not hours
Upload a video, audio file, or existing subtitles. Get an accurate transcript, translate into 100+ languages, and export as SRT, VTT, TXT, or PDF.
Captions shouldn't cost you a day of work
Manual transcription takes hours. Auto-captions on most platforms are inaccurate and English-only. And when you finally want to reach a new audience, most tools charge you twice — once to transcribe, again to translate — while burning through a tiny pool of included minutes.
There's a faster way.
Three steps, no editing software

Frequently asked questions
What is Subnova?
Subnova is a web-based service that automatically generates subtitles from video or audio and translates them into 100+ languages. You upload a file, and it returns accurate, time-coded subtitles in the original language plus any translations you need. No software to install — it runs in your browser.
How accurate are the subtitles?
Transcription is powered by Whisper large-v3-turbo, one of the most accurate open speech-recognition models available. Accuracy is highest with clear audio, and a custom glossary keeps your names, brands, and terms spelled correctly. The spoken language is detected automatically.
How many languages are supported?
Subnova recognizes speech in around 99 languages and translates subtitles into 100+ languages. Language detection is automatic, so you don't need to specify the source language.
What file formats can I export?
You can export every language as SRT, VTT, TXT, and PDF — ready for YouTube, web players, LMS platforms, and print. Select several files in the library to download them all at once as a ZIP archive.
Can I translate subtitles I already have?
Yes. With translate-only mode you upload an existing SRT, VTT, or TXT file and translate it or convert the format without re-transcribing. Minutes are counted from the subtitle timeline, so it's far cheaper than processing the original video.
How fast is it?
An hour of audio is typically processed in minutes rather than hours. Processing time depends on file length and current load, but Subnova is built for fast turnaround on large backlogs.
How much does it cost?
You start free with 30 minutes of transcription and translation — no credit card required. Starter is $10/month for 10 hours, Pro is $20/month for 30 hours, and Business is $50/month for 90 hours. Translation is included in every plan, and you can cancel anytime.
Is translation billed separately?
No. Translation is included in the normal workflow and does not double-charge your minutes. With many other tools, translating subtitles consumes a second pool of minutes — Subnova keeps it in one flow.
Do I need to install anything?
No. Subnova is fully web-based. You work in your browser on any operating system — just upload a file and download the results.
What languages does the interface support?
The interface is available in English, Ukrainian, Spanish, German, French, Italian, Portuguese, Polish, and Turkish. Subtitles themselves can be transcribed in ~99 languages and translated into 100+.
Is my content kept private?
Your files live in your private library and are accessible only to your account. Deleted files go to the trash and are permanently removed, including from storage, after 30 days.
