Field notes
The landing page teaches through a single sentence: 猫が魚を食べているのを見た, glossed as “I saw the cat eating the fish.” Its central explanation treats のを as the hinge that packages the preceding clause as the object of 見た, rather than leaving the learner with isolated dictionary definitions. The page also describes chunk-level audio and sentence review, while noting that the product is being built by one person and is currently invite-only.
