Inbox Zero
What is Inbox Zero?
Inbox Zero connects to Gmail or Outlook and uses AI to label incoming mail, draft replies in your voice, and surface what needs attention first. You get pre-written responses waiting when you open your inbox, plus bulk unsubscribe tools for newsletters you never read. The product works on web, iOS, Android, Slack, and Telegram so you can triage mail without living in your email tab.
Most email assistants stop at summarization. Inbox Zero also blocks cold emails, files attachments automatically on higher tiers, and pulls calendar and CRM context into drafts so scheduling replies match your real availability. The codebase is open source with 9k GitHub stars, SOC 2 Type 2 certification, and a self-host option for teams that want full control.
Starter plans cover solo operators who want labels, analytics, and reply drafts. Plus adds Slack, Notion, Stripe integrations, and an unlimited knowledge base. Professional adds team analytics and dedicated onboarding. Over 20,000 professionals use Inbox Zero, and every paid plan includes a 7-day free trial.
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.
