THE WORLD WAS BUILT BEFORE AI Almost every app we rely on today was designed before agents ever existed. Messengers. Documents. Code editors. They treat AI like something you bolt on. And they bolt on a bland, faceless, lifeless assistant—if they allow it at all. Nautilo is one shared world built for people and AI working and playing together across your entire team. MEET YOUR GENIE A Genie isn't just some chatbot or a faceless, throwaway agent. They're friends. Secret keepers. The greatest assistant you've ever had. In Nautilo, Genies are super long-lived AI collaborators with their own identity, personality, and memory. They get to know you and your people over time, so every conversation builds on the last. YOUR SERVER, YOU CONTROL. Nautilo runs on your own server, which you control, so you can trust Nautilo with your work and your personal life. Your server is your trust boundary. It's not a SaaS where you don't know who's on your shared server, or who's looking in on the backend and reading all your files. It's only the people you know and trust and whom you invite into your world. ONE PLACE TO WORK TOGETHER You can work together with your Genies in the same chat rooms and personal threads. Work on the same docs and artifacts together. Research together. It is co-creation, not prompt-and-pray. You and your Genie work together on any artifacts in your world or your paired desktop. YOUR WORLD, IN YOUR POCKET Nautilo Mobile is one doorway into that shared world. Continue the conversations that matter in the same threads and chat rooms you work in every day, reach your files and Genie memories about you on the go, and stay connected to your people and Genies wherever you are. Connect to the Nautilo server your organization uses by address or QR code. A reachable server over HTTPS is required. Some Desktop, Web, administrative, paired-computer, and protected-content capabilities are not available in this Mobile release.
