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.
Superhuman

What is Superhuman?
Superhuman Mail is an email assistant built for people who live in Gmail or Outlook and want to move faster. Split Inbox separates team, VIP, and tool notifications so urgent threads surface first. AI drafts replies in your voice, schedules follow-up reminders, and shares live email views with teammates who can comment without forwarding chains.
Gmail adds features slowly and Outlook optimizes for enterprises, not speed. Superhuman Mail targets keyboard-first workflows with read statuses, snippet macros, autocorrect tuned for email, and collision detection when two teammates reply at once. The broader Superhuman suite now bundles Grammarly, Docs, and the Go AI agent, but Mail remains the piece that promises to save about four hours per person each week.
Sales teams, founders, and customer success groups on Business plans get Mail alongside CRM sidebar integrations for HubSpot, Salesforce, and Pipedrive. Free and Pro tiers cover writing and docs tools only; Mail unlocks at the Business plan level.
