For dyslexia, use a spell-checker. For grammar, use a basic grammar checker, like the kind of grammar checker that has come with MS word since the 1990s. But don't let a style-checker or an LLM rob you of your own voice.

Those are notorious for false-positives, false-negatives, and generally nonsensical advice. Not that the LLM-based alternatives are much better (looking at you, Grammarly), but still.
