Best AI Proofreading Tools for Mac (2026)

The best AI proofreading tools in 2026 are Echoo, Grammarly, ProWritingAid, LanguageTool, and Hemingway Editor. Echoo is the best AI proofreader for Mac because it checks grammar, spelling, punctuation, and style inside any macOS app from a keyboard shortcut. Grammarly and ProWritingAid are the most feature-rich browser and desktop proofreaders, while LanguageTool is a strong free, privacy-friendly option.

An AI proofreading tool goes beyond spell-check: it understands context, so it catches wrong-word errors (their/there, its/it’s), awkward phrasing, punctuation mistakes, and tone inconsistencies that a dictionary check misses. As with rewriting, the deciding factor is where you write. A browser proofreader is fine for web writing; a tool that proofreads inside any Mac app is faster if your writing is spread across native apps.

Here are the AI proofreading tools worth considering in 2026, and what each is best for.
