What is it?

PotPlayer_ChatGPT_Translate is a subtitle translation plugin for PotPlayer, the Windows video player. It sends subtitle lines to an AI model through a chat/completions endpoint and displays the translated text while the video plays. Because the model sees the wording rather than matching words one by one, it can handle idioms, jokes and cultural references better than conventional subtitle translators.

The plugin ships in two variants. The context version passes recent subtitle lines to the model, which usually improves accuracy at the cost of more latency and tokens. The no-context version translates each line on its own, which is faster and cheaper. Users set the model name, an optional custom API base URL, and an API key in PotPlayer's plugin panel. Endpoints that need no key are supported by adding a nullkey option.

Optional settings cover retries, request delays, context caching, a prompt mode for smaller models, and a check that discards abnormally long translations. A Windows installer handles setup, and manual installation is also documented.
