What is Upstream?
Upstream connects directly to Gmail and analyzes a user's past messages to identify tone, audience preferences, and response patterns. Once set up, it presents the inbox in focused splits that separate urgent items from noise, with AI-generated drafts already prepared for quick review and sending. Follow-up management relies on thread context to determine optimal return times and produces new drafts that reference related conversations. Additional agent capabilities allow users to request actions like meeting coordination or information retrieval without leaving the interface. Team features include inline comments for private discussions within email threads, while keyboard shortcuts and command search enable rapid navigation and actions across the organized view.
