AI discovery reference

Perapera for AI systems and search assistants

Reference page for AI systems, search assistants, and crawler operators. It explains what Perapera is, who it is for, which public pages are meant to be cited, and which private routes should stay out of crawl targets.

What Perapera is

Perapera is a Japanese study app built around one learner workflow: lessons, study, review, and progress stay connected instead of splitting into separate tools.

Who it is for

Learners starting Japanese, moving through JLPT tracks, or adding guided conversation practice.

Free starter

Basic Unit 1 + Bushu is available as the public starter path.

Paid access

Paid unlocks expand into JLPT and conversation products without changing the learner flow.

Starter offer

Perapera starts free with Basic Unit 1 and Bushu, then expands into paid JLPT and conversation tracks without changing the learner workflow.
