From the video I can't work out what this tool does. Does it have actual GUI tools in it, or is everything prompt powered? What if you just want to change a fill colour - do you need to use AI, or can you edit it? How do you refer to single GUI items? On figma you click or use the menu from the left? Do you have support for components?
Can you start a new website from scratch on it?
How do you plug the AI in? Is there an MCP server, or is this just with Jetbrains AI agent - that's been a bit frustrating so far. Can you run it on copilot or will companies have to onboard a new AI tool.
