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.
MailMentor

What is MailMentor?
MailMentor is an email assistant and prospecting tool built around a Chrome extension that scrapes contacts from news articles and company pages while you browse. It builds lead lists, exports them as CSV, and pushes leads through Zapier or webhooks when you want them in another CRM.
Traditional databases miss prospects buried in press releases or niche sites. MailMentor scans the page you are on, surfaces organizations and contacts other tools skip, then layers sequence building, Gmail outreach, and case-study insertion on paid tiers. Over 4,000 sellers use it according to the homepage, with Capterra reviews linked on the site.
Plans run from a free tier through $9 Prospect, $49 Outreach, and $79 Scale with up to 1,000 monthly contact scrapes. Sales reps mining news for leads, recruiters sourcing hiring companies, and founders doing outbound without a full SDR stack are the clearest fits.
