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, local audio and video files, 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 analyze local audio and video files, 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. 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, document and media understanding, and multi-step or long-running tasks. ReadOS Pro is available through Apple In-App Purchase as an auto-renewing annual subscription or a one-time lifetime purchase. ReadOS Pro also requires a supported AI provider account or compatible API connection. Provider subscriptions, usage quotas, and model or API fees are separate and are not included with ReadOS Pro. Availability and results can vary by source format, selected provider or model, network access, and permissions. Start with what you are reading. Keep the context. Build what comes next.
