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.
Serif.ai (formerly EmailTriager)

What is Serif.ai (formerly EmailTriager)?
Serif.ai, formerly EmailTriager, is a Gmail email assistant that sorts incoming mail and drafts replies in your voice while you review and send. It plugs into Gmail with a one-click install, trains on your past emails to build a private knowledge base, and surfaces ready-to-send drafts in about a minute. The product sits in the email assistant category for people drowning in inbox volume.
Compared with generic AI writers, Serif.ai emphasizes True Voice training from your sent mail rather than generic tone presets. It never sends email on your behalf, and billing counts only Accepted Drafts you send with less than 20 percent word changes.
The assistant triages messages, drafts follow-ups, and keeps workflow inside Gmail without a Chrome extension. Serif Inc runs the product, which is CASA Tier 2 accredited and states that training emails are not stored after the knowledge base is built.
Founders, support leads, and operators with heavy Gmail volume use Serif.ai to turn email into reviewing drafts instead of writing every reply from scratch.
