Grammarly
Tap a star to rate
Grammarly's core business is checking grammar and tone, and its AI email writer is built right into Gmail and Outlook. You type a prompt or a few words, and it generates a full draft. The AI knows your writing style from Grammarly's existing profile and adjusts suggestions accordingly.
It's strongest for people already using Grammarly for writing checks who want a handy email draft generator. The integration works smoothly across Gmail and Outlook, but it's less specialized than tools built solely for email, so it may not match dedicated platforms' features for personalization or A/B testing.
