NeuroSpell is a deep-learning auto-corrector for text, covering French, English, Spanish, German, Italian, Portuguese, Irish and a considerably longer list beyond the usual set.
Language breadth is the reason to look at it. Grammar correction is dominated by English-first products where other languages are an afterthought, and support drops off sharply outside the largest markets – so anyone writing in Irish, or in a language with a small commercial user base, is served badly or not at all. A tool built multilingual from the start behaves differently from one with languages bolted on.
The approach is correction rather than rewriting, which suits people who want their own sentence fixed rather than replaced – a meaningful distinction if you write in a second language and dislike having your voice smoothed away. Correction quality varies by language, so test the one you actually need rather than trusting the list length.
