• Project knowledge. Files and links in one place.
• Project AI. Answers with the project in mind.

Vivian

If you want it: chat with a model, attach files, images and voice, and let Vivian use your apps, the web and, if you allow it, your computer. Without your consent, or when your platform switches AI off, it stays off.

Works in Boards, uTodo, uDoc, uSheet, Calendar and more.

• Your provider and model. Chosen per platform in the Agent app.
• Files, images and voice. Ask about them.

• Time clock and timesheet. Counted from the contract start.
• Requests centre. Vacation, sick leave, corrections and swaps, with approvals.

App Studio

Plan the app with the AI, let it write the code, watch it run in a live preview and publish it for your platform or as a website. Apps can work with your uOS data, with several people at once in real time, and with outside services your platform approves.

• Plan, then build. Discuss first, then let the AI write and change the code. Edit it yourself whenever you like.
• Live preview and testing. The app runs in an isolated sandbox next to the chat. "Test App" opens it as a real app window.
• Real-time apps. Lobbies, rooms and shared state for apps that several people use at once.
