InboxChat

What is InboxChat?
InboxChat is a Gmail email assistant that replaces manual filter rules with AI-powered automations written in plain English. Describe what to sort, like "all travel confirmations" or "client invoices," and InboxChat moves matching emails to labels, drafts replies, or extracts data automatically. A 14-day free trial requires no credit card.
Gmail's built-in filters need exact syntax like from-address and keyword combinations, which breaks when senders change addresses. InboxChat uses natural language prompts and contact tags such as Newsletter, Travel, and Family to route mail, plus a screening system that makes unknown senders earn inbox access before their messages appear.
Professionals drowning in promotional mail, small businesses sorting client invoices, and frequent travelers collecting flight confirmations use InboxChat to reclaim the 4+ hours per week the site claims users save. The Professional plan at $14 per month includes up to 10 automations and CASA Tier 2 security certification.
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.
