## What it is
LLPlayer is a Windows media player built for language learning, featuring dual subtitles, AI-generated subtitles via Whisper ASR, real-time translation, and OCR of bitmap subtitles. It integrates yt-dlp for online video playback and supports word lookup, subtitle search, and LLM-based context-aware translation.

## Use cases
- watch videos with dual subtitles for language learning
- generate subtitles automatically with whisper from any video
- translate subtitles in real time while watching
- convert bitmap subtitles to text with OCR
- look up words in subtitles instantly
- play online videos with yt-dlp and generate subtitles
- study japanese or other languages with video subtitles

## When to choose
- you need dual-language subtitles that never overlap
- you want AI-generated or OCR subtitles during playback
- you want integrated translation and word lookup for language study
- you want to stream online videos with subtitle features

## When to avoid
- you need a cross-platform player (Windows/WPF only)
- you just want a lightweight general-purpose media player without subtitle tooling
- you need offline playback without GPU or translation engines configured
