Clevermail

AI Gmail assistant that drafts polished, on-tone replies for you

AI email drafting in Gmail

Give a short instruction plus context about your business or recipient and receive a complete, professionally phrased email draft ready to review and send, without leaving the Gmail compose window.

Personalized, on-tone output

Drafts are generated from the context and inputs you provide, so the result targets your actual situation and relationship rather than producing generic boilerplate copy.

Multilingual support

Compose and generate messages in languages beyond your native one, which helps when corresponding with international clients, partners or colleagues.

Send directly from the extension

Review the generated draft and send it from within the extension flow, keeping the read-reply-send loop inside Gmail instead of switching between apps.

Strengths & Pros

+Generates complete, professional Gmail drafts from a short prompt and context
+Works inside Gmail, so there is no separate app or workflow to learn
+Multilingual output is useful for international correspondence
