Thinking about switching from Yomitan or Anki?
immit pairs perfectly with your existing setup — or works as a cleaner all-in-one replacement. If you're maintaining Anki decks by hand or running a Yomitan + Anki workflow and want something simpler, immit gives you both lookup and SRS in one polished extension, zero configuration required. Works great for immersion learners.
