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.
Instantly.ai

What is Instantly.ai?
Instantly.ai runs cold email outreach with AI agents that find leads, write copy, and launch campaigns from one workspace. Its Copilot can build a full campaign from a prompt, while AI Workflows route replies, tag visitors, and trigger follow-ups without manual setup.
Most sequencers stop at sending. Instantly bundles unlimited email accounts and warmup, a 450M+ B2B lead database, waterfall enrichment across 5+ providers, and revenue tracking tied to pipeline and conversions rather than open rates alone. The Scale bundle adds an AI Reply Agent and Unibox for managing replies inside the same tool.
Sales teams and agencies use it to scale outbound without juggling separate lead lists, warmup tools, and copywriters. Instantly cites 50,000+ sales teams on the platform and customer stories reporting 100,000+ emails across 20+ domains with 20%+ reply rates.
