KnowMeNote is a quiet place for drafts, ideas, transcripts, and messages you want to finish before sending. Write freely, then tap Copy when the text is ready. The app learns from corrections you make yourself. Names, words, and phrases you often change can be replaced automatically the next time they appear. If a replacement is wrong, undo it immediately and the model learns to avoid that mistake. Highlights: • Multiple notes for separate drafts • One-tap copy to any other app • Independent learning for each of 16 supported languages • Undo, disable, or reset learned preferences • Input, replacement, and per-language learning stats • Keyboard, dictation, pasted text, and transcript support • Optional private iCloud sync Learning runs on your device. If you enable iCloud, notes and learning signals sync through your private iCloud account. You can reset learning data without deleting your notes.

Verdict
The clearest difference is in-app purchases: 懂我筆記本 at none against Bird Diary's 3. Bird Diary's advantage is update cadence (every 3 weeks vs every 2 months). On price, ads, device support and iOS requirement there is nothing between them.
