Why Tago
We combine standards from Korean language education with hands-on AI product experience, designing for the learner’s next step rather than a flashy result.

Korean language education at BA and MA level, together with teaching experience, informs our assessment and content design.

We go beyond a score to show why something should change and what to practise next.

Product design, content, validation, and implementation follow one shared standard as we prepare to launch.
BA → MA · Korean language education · Product design → working software
