subsai

What it does

Generates subtitles from audio or video through whichever interface suits the job — web UI for one-offs, CLI for batches, Python for pipelines — with a choice of Whisper variants so you can trade accuracy against speed, plus translation. Docker available. Try a short clip across a couple of models first; the right choice depends on your material. Local transcription stays local, but translation backends may not. GPL-3.0.

subsai FAQ

Is subsai free?

Yes. It runs on your own machine, so there is no usage-based cost either.

Do I need to install anything or write code to use subsai?

It needs the command line. If you are not comfortable typing commands, expect to get stuck during setup.

Does subsai work on a phone?

No. It needs a computer.

Can I use subsai commercially?

The licence is GPL-3.0. Using it commercially is fine, but if you distribute something built on it you may be required to release that under the same licence. Keep it internal, or check before distributing.

How it compares

The conditions that decide whether you can actually use it, side by side.

"Sends data out" means your input is uploaded to someone's server. Pick "No" when the material cannot leave your organisation.
