Mailyr

What is Mailyr?
Mailyr writes Gmail drafts from a subject line inside a Chrome extension, so you never leave your inbox to open a separate chat window. Open the composer in Gmail, type a subject, pick a tone and length, and the extension inserts a full draft you can edit before sending.
Compared with generic writing assistants, Mailyr stays inside Gmail and optimizes for outbound email speed rather than long documents. The free Starter tier runs on mid-tier models like GPT-4o mini and Gemini Flash with 14 complimentary credits, while Premium at $4.90 per month unlocks GPT-4o, Claude Sonnet, and 250 generated emails with faster throughput and priority support.
Busy professionals, founders, and support reps use Mailyr when they answer dozens of similar emails daily and want grammar-checked drafts without copying text between tabs.
