Mailwise — AI Assistant for Gmail

Gmail AI Assistant adds a small AI-powered button directly inside Gmail's compose window, so you can improve your email drafts without leaving your inbox or copy-pasting into a separate chat app. HOW IT WORKS While writing an email, click the sparkle button that appears in your compose window. Choose a quick action — Improve Writing, Make Shorter, Make Formal, Make Friendly — or type your own custom instruction (e.g. "add a polite follow-up line" or "translate to Spanish"). Your draft is rewritten in place, instantly. FEATURES - One-click rewriting inside Gmail's native compose window - Four built-in quick actions: Improve, Shorten, Formalize, Friendly - Custom instructions — tell it exactly how to rewrite your email - No copy-pasting between tabs or apps - Works with your own Anthropic API key — you control usage and cost WHO IT'S FOR Anyone who writes a lot of email and wants a faster way to polish tone, length, or clarity — professionals, freelancers, non-native English writers, or anyone who wants a second pair of eyes on an important message before hitting send. SETUP This extension requires a free Anthropic API key (console.anthropic.com) to function. Click the extension icon after installing to enter your key. Your key is stored only in your browser's local extension storage and is never sent to us — it's used only to call Anthropic's API directly from your browser. PRIVACY This extension only reads the compose box you're actively writing in when you click the assist button. It does not read your inbox, other emails, or any Gmail data beyond the active draft.
