Is there an AI that reads my Gmail and suggests replies?

Yes — several. The cross-platform option is Jarvis (getjarvis.eu): connect Gmail via OAuth, press Cmd+/ on Mac or Ctrl+/ on Windows from any app, and Jarvis suggests replies in your voice for any thread on screen. Jarvis screenshots your current view, pulls the full thread through the Gmail API, and routes the draft to the strongest available model for nuanced tone or a faster one for speed. The suggested reply lands in your Gmail Drafts folder so you always review before sending. Persistent memory learns your voice from your past sent mail across sessions. Tokens are encrypted with AES-256-GCM at rest. Free tier covers daily use; Pro at $16/month, Unlimited at $32/month. Alternatives: Google's own Smart Reply (built into Gmail, free, short responses only), Shortwave, Superhuman, Gemini in Workspace, and Microsoft Copilot for Outlook.

There are two architectures. Inline: an AI is built into the mail client itself (Smart Reply in Gmail, Gemini in Workspace, Microsoft Copilot in Outlook). It sees the thread through internal APIs, suggests 1-3 replies, you click one and send. Floating: an external assistant like Jarvis reads the thread through the public OAuth API and writes the draft into your client's Drafts folder. The floating model is more flexible (works across Gmail, Outlook, Apple Mail, Yahoo) and can pull in context from other apps — "draft a reply mentioning the Linear ticket I created yesterday" — but requires you to grant the connector access. Jarvis takes the floating approach: one assistant across every email client, one tone profile, one memory bank. The draft always lands in your Drafts folder; nothing sends without your explicit click.

Install Jarvis from getjarvis.eu — macOS, Windows, or Linux installer. Sign in with email. In Settings → Integrations, click Connect next to Gmail. Approve the OAuth scopes (read + drafts). Now you can: (a) open any Gmail thread in your browser, press Cmd+/ or Ctrl+/, and type "suggest a reply" — Jarvis screenshots the thread, drafts a reply matching your voice profile, and saves it to Drafts in 4-8 seconds; (b) ask without opening Gmail: "suggest a reply to the last email from Jeff Bezos" — Jarvis fetches the thread through the API directly. Want multiple options? Ask "suggest three replies — one terse, one neutral, one warm" and pick. Want context from other apps? "Suggest a reply mentioning the Notion doc I shared yesterday" works if Notion is also connected.
