General

Does it really run locally?

Yes. Transcription runs on your own Mac. AI correction runs locally by default too. If you choose cloud (Pro), it uses your own key.

Who is Subtitle Studio for?

For video editors, content creators and copywriters who want fast, reliable subtitles without transcribing or timing manually. Made for creators, not as a professional subtitle suite.

Which systems does it run on?

On a Mac with Apple Silicon (M1 or newer). A Windows version is planned.

How do I get the best results?

Export an audio track without music and sound effects. Clear, dry speech delivers the most accurate subtitles; music and SFX can interfere with transcription.

Budget & Pro

What's the difference between Budget and Pro?

Budget is a local subtitle tool (Dutch and English) for one user. Pro adds AI correction, 22 languages and use on up to 2 Macs.

Can I try it first?

Yes. With the free trial you try Subtitle Studio on 3 of your own videos, with the complete Pro workflow and no time limit. After that your work stays available; for new videos you choose Budget or Pro. Every licence also comes with 14 days money back, even after activation.

Can I upgrade from Budget to Pro later?

Yes. Start with Budget and switch to Pro when you need AI correction, more languages or use on 2 Macs. Your settings, terminology and presets are preserved.

How many devices can I use?

Budget covers 1 Mac and is easy to transfer to another Mac. Pro can be used on up to 2 Macs, or by 2 users at once.

AI & costs

Do the AI features cost money?

The AI features work via optional connections with your own keys. Local AI correction is free; with a cloud provider you use your own key and pay per use, in practice a few cents to a few euros per hour of video. Speaker detection uses a free HuggingFace token. Transcription itself runs locally.

What exactly does AI correction do?

Whisper converts your audio to text. The AI correction then makes subtitles more readable and consistent, especially with fast speakers or unclear pronunciation. You control how active the correction can be.

Do my recordings stay private?

Yes. Transcription processes everything on your own machine: no upload, no cloud queue. AI correction also runs locally by default. Only if you choose a cloud provider yourself in Pro does the text (not the video) go to that service, with your own key.

Languages & export

Which languages are supported?

Budget subtitles in Dutch and English. Pro does 22 languages, with excellent results for NL, EN, DE, FR, ES, IT and PT.

What formats can I export to?

SRT and VTT, directly importable in Premiere Pro, DaVinci Resolve, Final Cut and on the web. Pro also supports TC-offset and 9×16 export; EBU-STL export is on the roadmap.

Will there be a Windows version?

Yes, it's planned. The Mac version (Apple Silicon) is currently the most refined and fastest.

Try it free on 3 of your own videos

The trial runs the complete Pro workflow. No payment details needed, just your e-mail address, and your video stays on your own Mac. What do you have to lose?
