Description

Novastart is an infinite canvas operating system designed to keep your desktop apps, teammates, and AI agents organized on a single endless workspace. Rather than toggling between tabs and overlapping windows, users can place applications like Gmail, Excel, WhatsApp, and Notion side-by-side. Novastart features real-time peer-to-peer collaboration with individual cursors, local data storage for privacy, and support for up to 10 visible AI agents working with their own cursors on the canvas.

Superhuman uses AI to triage, summarize, and draft replies at keyboard speed.
