Rool gives you a private computer in the cloud that you can talk to. Ask questions, create files, solve problems, and work through projects with an AI that builds on what you’ve already done. Each Rool Machine brings your conversations, files, and memory together. It can run software and carry out tasks with multiple steps, helping you go from an idea to finished work through a familiar chat. WORK WITH YOUR FILES Upload documents, PDFs, images, spreadsheets, and code. Ask Rool to read, edit, organise, or create files for you. Turn notes into a report, work through calculations, or build an interactive HTML page. CREATE AND EXPLORE Draft ideas, generate images, write code, and compare different approaches. Refine the results through conversation and keep what you create alongside the rest of your project. BUILD ON YOUR WORK Rool connects your notes, conversations, files, and decisions through persistent memory. Return to a project with its context still available, and ask your AI to use earlier work when planning what comes next. MAKE ROOM FOR DIFFERENT PROJECTS Use separate Machines for personal projects, work, or shared interests. Each has its own files and memory, helping you keep different parts of your life organised. WORK TOGETHER Invite others into a Machine to collaborate with the same AI, files, and project history. Changes sync in real time, so everyone can work from the same information. PRIVATE BY DESIGN Your work is stored in your own isolated Machine, hosted in the EU. Rool has no ads and does not sell your data or share it for third-party AI training. You can export your data whenever you choose. AI INCLUDED Advanced AI is built in. Rool automatically selects models for the task, so you can focus on what you want to do. Start with a free plan that includes AI access, persistent memory, and file storage. Paid plans offer higher usage and storage limits.
