Special KB is an adaptive cognitive keyboard for iPhone and iPad. Instead of simply correcting typos, it tries to work out what you meant to say and helps you say it. It is aimed at people whose needs standard keyboards overlook, including those living with dyslexia, aphasia, ADHD, autism, motor conditions such as Parkinson’s or MND, or low vision, as well as young children learning to write and anyone typing with one hand or in a rush.
Its Intent Recovery Engine understands sound and meaning. It can correct phonetic spellings such as “nolege” or “skool”, explain homophones like their, there, and they’re before you choose, and help you find a forgotten word from a description, rhyme, or sound. A built-in dictionary and thesaurus give instant definitions.
When you ask for it, AI sentence help can simplify, rewrite, or soften text, or check its tone. Nothing is changed without your approval. Special KB can also configure its accessibility settings automatically based on your answers to a few questions. It is free to download.
