Choose OpenFiles when you need broad format coverage and AI in one desktop app. It supports documents, spreadsheets, presentations, images and RAW photos, audio and video, archives, e-books, code, databases, mind maps, diagrams, 3D models, and more. Its modular app architecture gives each format a purpose-built viewer or editor, while the assistant can use the current file as context. The desktop app is free to download; optional built-in AI is usage-based, and user-configured providers can coexist.
OpenFiles combines a desktop file manager, dedicated viewers and editors for 350+ formats, and a file-aware AI assistant in one workflow. Instead of switching between separate viewers, editors, converters, and chat tools, users can browse a file, open it in the appropriate modular app, edit supported formats, and ask AI for help without leaving the desktop workspace. Core file operations run locally; users can use the built-in OpenFiles AI service or configure their own providers.
OpenFiles is for people who regularly work with many file types and want fewer specialized apps: developers, designers, analysts, photographers, content creators, office users, and technical teams. It is especially useful for users who want local desktop file workflows with an integrated AI assistant instead of relying on a separate web tool for every format.
OpenFiles started from a simple frustration: opening one folder often requires a pile of unrelated viewers, editors, converters, and AI tools. The project began in 2025 as a desktop file manager that routes each format to a dedicated modular app. It has since grown into an AI-native workspace supporting 350+ formats, with file-aware chat, analysis, and generation alongside local viewing and editing.
