Grammarly vs Apple Writing Tools vs SpellType

Pick the Mac writing assistant for the moment you are in.

Grammarly, Apple Writing Tools, and SpellType solve different writing moments. Grammarly is broad writing assistance. Apple Writing Tools help transform selected text. SpellType is private inline autocomplete for the sentence you are still typing.

Three tools, three writing moments

Tool Best fit Less ideal when
Grammarly You want grammar checking, proofreading, rewriting, tone help, AI prompts, and broad writing suggestions. Your main need is a smaller local Mac autocomplete layer that stays focused on the next phrase.
Apple Writing Tools You want to rewrite, proofread, summarize, or transform selected text using Apple's system writing features. You are still composing the sentence and want suggestions before selecting text.
SpellType You want private inline autocomplete for everyday Mac work writing across email, docs, notes, messages, and chat. You need a full grammar checker, broad style guide system, or selected-text summarization suite.

How to choose

Choose Grammarly for polish

If the most important job is grammar, proofreading, tone, rewriting, or team writing controls, Grammarly is the stronger category fit.

Choose Apple for selected text

If text already exists and you want to rewrite, proofread, summarize, or change it using system tools, Apple Writing Tools make sense.

Choose SpellType for flow

If you write many small work messages and want private suggestions before the sentence is finished, SpellType is the focused fit.

Common Mac work scenarios
