Read full description

Idle is a chat app built around widgets that lets your group chat do more than just talk. Because every group is different, so is every chat on Idle. Your rec softball team can add a calendar widget and a roster tracker. Your small business might need a shared Todo list widget or a place to share links. Your book club can create a poll or write in a shared notepad. And your neighborhood group can make announcements and add events to the board. In Idle, you never get features you didn’t ask for and you’re never missing the ones you need. WIDGES FOR ANY GROUP Every group has unique needs so only add the widgets that you need [Calendar] - Meetups, games, and sessions everyone can see at a glance [Events]- Post events with details and RSVPs so nothing slips through [Signup Sheets] - Keep tabs on attendance, scores, signups, or progress [Notepad]- Shared notes, lists, and agendas the whole group can edit [Paid Memberships] - Collect dues, fees, or contributions right inside the group [Polls] - Vote on the next book, the next date, the next anything [Announcements] - Pin the things that matter so they don't get buried New widgets are added regularly, so there's always more to choose from. CREATE YOUR OWN Need something that’s not off the shelf? Create your own custom one made just for your group. If your group has a need, your chat can meet it. SET THE VIBE Make the space feel like your group with custom wallpapers, your own emojis, and name tags. Idle Chat should feel like being in a friends’ living room, not the JPMorgan office.

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.
