Review

“The most polished, everywhere-you-type writing assistant.”

Grammarly's browser extension and desktop app follow you into email, docs, and social media, catching errors before you hit send.

The paid tiers add tone detection and clarity suggestions that go well beyond basic spellcheck, though the upsell prompts can feel frequent.
