## What it is
Memento is a free, open-source video player built on mpv designed for studying Japanese. It integrates a Yomitan-compatible popup dictionary, grammar-aware subtitle search, and automated Anki card creation via AnkiConnect.

## Use cases
- watch Japanese videos with a popup dictionary for looking up words
- mine subtitles and create Anki flashcards while watching anime
- search subtitles for grammar-conjugated forms of Japanese words
- use Yomichan/Yomitan dictionaries inside a video player
- stream Japanese content from websites with dictionary support
- replay and study dialogue from Japanese media with mpv plugins and shaders

## When to choose
- you study Japanese and want an all-in-one immersion and flashcard-mining player
- you already use Anki and Yomitan dictionaries and want them integrated with video
- you want mpv's flexibility (upscalers, plugins, config files) plus dictionary features

## When to avoid
- you need a general-purpose video player without language-learning features
- you study languages other than Japanese
- you don't use Anki and only want passive video playback
