ReadOS is an all-in-one, desktop-class AI agent workspace for iPad, built around the place serious work often begins: reading. Open a PDF, collect research, inspect evidence, create a report, analyze data, build office files, and continue the task without rebuilding context across separate apps. ReadOS keeps source materials, reading position, selections, files, and project context connected so you can move from understanding to creating. READ WITH CONTEXT • Open PDFs, EPUBs, Markdown, images, audio, video, and common office files. • Navigate document structure and page references when the source provides them. • Annotate PDFs, take notes, organize tabs, and export annotated documents. • Build knowledge maps and visual explanations connected to source material. RESEARCH WITH READEX Readex is the AI agent inside ReadOS. When you choose to share content with it, Readex can work with the current document, selected passages, attachments, webpage context, and files in your workspace. Use Readex to: • Summarize and compare source material. • Develop study guides, research plans, and structured notes. • Trace an answer back to relevant pages and context. • Work across multiple files while keeping the research question visible. CREATE, AUTOMATE, AND DELIVER With ReadOS Pro, Readex can help: • Create and edit documents, spreadsheets, and presentations. • Analyze data with Python and JavaScript. • Build charts, tables, interactive visualizations, and knowledge maps. • Browse the web, inspect pages, collect relevant context, and carry out browser tasks. • Transcribe and examine audio or video, extract useful frames, and continue from a playback position. • Carry out multi-step and long-running tasks across available files and tools, with progress you can review and stop. DESKTOP-CLASS WORK ON IPAD ReadOS combines document reading, file-based projects, browser automation, code and data tools, and office deliverables in one workspace. Move from a chapter to a study guide, from a paper to a dataset, or from research notes to a polished report, spreadsheet, or presentation without starting over each time. FREE AND PRO ReadOS Free includes library management, local file opening and playback, PDF annotation, notes, navigation, tabs, workspaces, and annotated-PDF export. ReadOS Pro unlocks Readex and advanced AI-assisted work, including browser automation, creation and editing tools, code and data analysis, audio/video understanding, and multi-step or long-running tasks.
