Whether you are studying for the JLPT or just trying to navigate native Japanese websites, Tsukeru is designed to make reading effortless.

It never runs passively in the background. - Zero Telemetry: We do not collect, track, or store any user data. - Ephemeral Processing: Text is sent to the backend strictly to apply readings, processed entirely in memory, and immediately discarded.
