5.0 out of 5
Scored by a Toolio reviewer after real useOur verdict
This plugin translates LINE messages in real time as you type or receive them, detecting the language automatically across more than 40 supported languages. It also keeps a translation history so you can revisit past conversations. It's an unofficial, third-party plugin rather than something built by LINE itself, though its 5-star rating from 224 reviews suggests it works well in practice.
