I've never felt a leap this big in a product before. @Replit just launched Agent 4. We jumped on a call with 4 people in the same Replit workspace. Everyone building at the same time. One person was designing on the canvas. Another spun up a web app. Someone else was generating a slide deck. All running in parallel, all sharing context with each other. That's the thing that hit me. You're not just building faster. You're building together. Websites, mobile apps, slide decks, spreadsheets, animations. Everyone creating different artifacts inside one shared project. The canvas is my personal favorite. You sketch out ideas, drop in designs, iterate on variants right there on screen. Then you hand it to the agent and it just gets it. When a task finishes you review it and merge it back into the main project. The agent handles all the reconciliation. It feels less like using a tool and more like having a team.
