What is the best way to mine vocabulary from anime that has no soft subtitles?
YuzuLingo · Nov 1, 2026
When an anime has no downloadable subtitle file, you need OCR to turn the burned-in text into selectable words. Once the text is recognized, you can hover a word to see its dictionary entry, then export the word, reading, definition, and a screenshot to Anki or another SRS in one click.
Why sentence mining usually assumes soft subs
Most sentence mining guides start with an SRT or ASS file. Tools like subs2srs, asbplayer, and Migaku parse that file to align audio, text, and screenshots. If the anime only has hardsubs, those tools have no text track to work with.
The OCR step
An OCR tool crops the subtitle region of the video frame, runs recognition on your device, and outputs the Japanese (or Chinese, Korean, etc.) string. This happens in real time while you watch. The recognized text appears as a selectable overlay on top of the video.
Dictionary lookup on the recognized line
Once the text is in the page, hover a word to open a dictionary popup. The popup shows the reading, part of speech, and glosses from your installed dictionaries. If you have pitch or frequency zips, those attach too.
Export fields
A one-click export sends the expression, reading, definition, full sentence, screenshot, and sentence audio to Anki via AnkiConnect. You do not need to copy and paste anything. The card is ready to review as soon as you finish the episode.
Comparison to soft-sub tools
asbplayer, Migaku, and Language Reactor need a subtitle track or ASR transcript. They cannot read pixels. If your source only has hardsubs, an OCR-based extension is the missing piece that turns the image into text so the rest of the mining flow can work.
