Remail vs Shortwave

Remail drafts and replies to Gmail messages from a Chrome extension and web app, pulling context from the thread plus your knowledge base when you need a fast answer. Pick positive or negative quick replies, set a tone, or type a short prompt and get multiple draft options you can send without rewriting from scratch.

Unlike single-purpose email writers, Remail bundles an AI sidebar, PDF and YouTube chat, LinkedIn post tools, and side-by-side LLM comparison in one browser extension. That breadth targets people who want email help without opening a separate chat tab for every task.

The product lists 210,000+ users and a 4.9 rating on the Chrome Web Store, with Gmail extension and Google Workspace marketplace listings. Pro starts at $19 per month with 6,000 queries; a 7-day free trial is available before you commit.

Shortwave is an AI email client built by former Google engineers that wraps Gmail with inbox organization tools and an agent you can prompt to search, write, schedule, and filter mail. It runs on iOS, Android, Mac, and Windows and syncs with Gmail accounts. The app positions itself as a spiritual successor to Google Inbox, with bundles, splits, and keyboard shortcuts at the center of daily triage.

Most Gmail add-ons bolt on one feature. Shortwave treats the whole inbox as a workflow surface: you triage with bundles and todos first, then ask the agent to draft replies, run natural language search across years of mail, or spin up filters written in plain English. That combo of Inbox-style organization plus a prompt-driven assistant sets it apart from Superhuman-style speed clients and basic AI summarizers.

Sales reps, founders, and support leads use it to split high-priority threads, track read receipts, and share live threads with teammates without pasting screenshots into Slack. Teams on Gmail who miss Inbox bundles or want calendar-aware scheduling from inside mail tend to stick with it once they adopt the Shortwave Method triage flow.
