Grammarly

Free, then from $12/mo

The most widely used writing assistant — grammar, tone, and clarity checks everywhere you type.

Summary

Grammarly's browser-everywhere approach (email, docs, social) is its core advantage — it catches errors in context rather than requiring you to paste text elsewhere. The free tier covers basic grammar well; the paid tier's tone and clarity suggestions are genuinely useful but occasionally over-suggest for stylistic writing.
