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.
Ellie

What is Ellie?
Ellie drafts email replies in your voice inside Gmail or Outlook before you hit send. Connect your inbox and wake up to responses already sitting in your Drafts folder, written in the thread context and matched to your tone. You review every message before it goes out; Ellie never sends on its own.
Most email assistants generate generic text you still have to rewrite. Ellie trains on up to 200 of your sent emails on the Casual plan (1,000 on Business) and pulls from a knowledge base you upload so replies cite your actual policies and CRM data. Business and Professional plans add background auto-drafting and auto-categorization, while Casual users trigger replies manually through a browser extension in Gmail, Outlook web, or Fastmail.
Support teams, founders, and sales reps drowning in inbox volume use Ellie to clear reply backlogs. Plans range from $19 per month for 25 daily replies to $79 per month for unlimited replies and up to 3 connected accounts per user. A 7-day free trial requires no credit card, and Microsoft 365 customers can buy through AppSource.
