Mailr
Mailr drafts and replies to email from a Chrome extension you open right in the browser. You type a short instruction describing what you want to say, pick one of more than 10 tones such as friendly, informal, or persuasive, and Mailr generates the full message in one click.
Compared with inbox-native assistants that plug into Gmail directly, Mailr stays a lightweight Chrome add-on focused on composing new mail and quick replies rather than auto-drafting every incoming thread. The free tier caps you at 2,000 words, while Premium raises that to 100,000 words per month with faster generation and early beta access.
Mailr suits professionals who live in Chrome and want help starting or finishing messages without switching tabs. The site notes Mailr was acquired by MailWiz, which now offers a separate Gmail-integrated product at mailwiz.app, but the Mailr extension and pricing page remain live on mailr-ai.com.
