SpellType vs Grammarly

Grammar and proofreading Strong fit. Grammarly is built around spelling, grammar, tone, and proofreading suggestions. Not the main job. SpellType focuses on writing speed and autocomplete.
Rewriting finished text Strong fit for changing tone, length, formality, and clarity after text exists. Useful before the rewrite stage, while you are still forming the sentence.
Private Mac autocomplete Broad cross-app writing assistant with account-based AI features. Designed around local Mac autocomplete for work drafts.
Routine work replies Helpful when you want writing suggestions, AI prompts, or polishing. Best when you want the next phrase inline without opening another writing flow.
