Your words, on your phone.
Vocab finds names and uncommon words in your public ATProto records. Review the suggestions and teach selected words to Apple’s spellchecker.
Your vocabulary is processed and stored on your iPhone. Sign-in establishes your identity; Vocab does not publish records or send your writing to a model service.
This experimental app tests how learned words affect typing. Autocorrection, predictions, and Dictation may behave differently.
