LLPlayer is a language learning media player and AI subtitle generator that integrates large language models for real-time audio transcription and translation. It functions as an LLM-integrated video player and SRT transcription tool, utilizing local or remote AI models to generate text subtitles from audio and video streams.
The project distinguishes itself through a contextual translation workflow that sends preceding subtitle lines to language models to maintain conversational flow and sentence structure. It also includes an optical character recognition system to convert bitmap-based subtitles into searchable and editable text.
The software provides a specialized environment for language study, featuring dual subtitle display with independent rendering to prevent visual overlap and a searchable sidebar for timestamp-linked navigation. It includes dictionary and lookup utilities that sync active subtitles to the system clipboard to trigger word definitions via external browser extensions.
Additional capabilities cover online video streaming, external subtitle downloads, and the export of AI-generated transcriptions to standard SRT files.
