Useful app for pitch accent with some caveats

The app is useful for its original intended purpose but the AI additions are gimmicky. I see there is an option to turn AI explanations off now, which is handy. I suspect some of the entries themselves are AI generated, as are the pronunciations, albeit in very realistic voices. I’ve noticed examples of database entries showing and speaking pronunciations for readings that don’t exist in Japanese, for example, giving an on’yomi reading and audio recording for something that is only ever read in kun’yomi.
