License / pricing

GPL-3.0

What it does

Show two subtitle tracks at once, generate subtitles from the audio when a video has none, translate lines in real time, turn image-based subtitles into text, and look up any word straight from the subtitle. Online videos can be played directly. Windows 10 (64-bit, 1903 or later) and Windows 11 only - it does not run on macOS or Linux. Translation can use local engines such as Ollama or LM Studio, so nothing has to leave your machine.

LLPlayer FAQ

Is LLPlayer free?: LLPlayer itself is free, but it needs an API key for an external AI service. That service charges separately, though some have a free tier.
Do I need to install anything or write code to use LLPlayer?: You install it like a normal desktop app. No command line involved.
Does LLPlayer work on a phone?: No. It needs a computer.
Can I use LLPlayer 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.
