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.
ChatGPT Services

What is ChatGPT Services?
ChatGPT Services hosts Gmail add-ons from Klart AI that write, translate, summarize, and analyze email inside your inbox. AI Mail Assistant adds reply generation, draft polishing, 13-language translation, ChatGPT Q&A, and tone or ethics analysis to Gmail through the Google Workspace Marketplace.
Unlike standalone ChatGPT tabs, these tools live in Gmail's sidebar so you generate replies, insert drafts, and translate threads without switching apps. A separate AI Label Assistant product auto-labels and archives mail on an hourly schedule using your existing Gmail labels, with custom instructions when label titles alone are not specific enough.
The suite also includes Klart Prompts for GPT, Midjourney, and reverse prompt engineering. Plans start with 10 free AI Mail Assistant requests per month, paid tiers from €4.99 monthly, and Stripe or PayPal billing with cancel-anytime subscriptions.
