Tatomo

Tatomo is a Chrome extension that converts Gmail's shared inbox into a functional support desk for Google Workspace teams. It adds shared internal notes to email threads, automatically generates sequential ticket IDs, enables team pings, and applies custom support footers—all without forwarding data to external services. The maker reports building it with AI coding tools to replace their $10k/year support platform.

Features include a local AI assistant using Chrome's built-in Gemini Nano for thread summarization and sentiment analysis, ticket attachments stored in Google Drive, and a people-in-thread resolver for quick context. All data stays in your organization's Drive. The extension uses Google Sheets as its data store, with no backend server required.
