No setup. Press play and study.
Native subtitles over YouTube, Netflix, Crunchyroll and your anime sites. Every word is a dictionary. Every sentence is one click from Anki. And it never asks for your money.
Permanently free. No paywall, no trial, no locked tier. Also on Floorp, Opera and Brave.
Hover a word
This is the whole loop. Kitsumi draws native subtitles over the player, and every word opens a Yomitan-format dictionary: reading, meaning, inflection path. Japanese and Chinese are tokenized as compounds, so you hover the word, not one character.
Features
{{ solvedLabel }}
One hotkey, or a site you list, and each speech bubble in view gets a plate right where the text is, vertical or horizontal to match the art, with lookups on every word. Careful or Thorough reading, Normal or Loose confidence.
Your dictionaries, mined words, known-word lists and stats live locally. The network is touched only when you ask for subtitles or a dictionary.
{{ f.body }}
Per-preset speed, opening flicker, continuous flicker and light sweeps. Ten UI themes for the popup.
Languages
Japanese gets the full treatment: compound tokenization, readings, inflection paths, JLPT-style levels. Every other language runs on Yomitan-format dictionaries from a catalog of openly licensed sources, or the ones you bring.
The interface itself speaks 20 languages, built per locale so the popup loads only yours.
Free forever
Every feature ships to everyone: dictionaries, OCR, the manga reader, Anki mining, SRS, tracking. There is no premium tier and there never will be. Kitsumi exists because it should, and it runs on people who feel the same way.
