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.

What is rasa.io?
rasa.io sends association and nonprofit members individualized emails instead of one blast to the full list. Each subscriber gets a Smart Newsletter built from their engagement history, so membership, marketing, and event teams can run every send from one platform with shared member intelligence.

Pricing scales by organization revenue and product scope with no per-contact fees, and the company cites 15 to 40% engagement lifts within 90 days for association clients.
Membership directors, marketing managers, and event coordinators use rasa.io to keep members engaged between renewals, promote events to likely attendees, and consolidate newsletters, campaigns, and drip sequences. The platform has served associations for nine years and reports sending about one million unique emails daily.
