Readest opens EPUB, MOBI, AZW3, FB2, CBZ, TXT, and PDF files across macOS, Windows, Linux, Android, iOS, and the web. Readers can switch between scrolling and paginated layouts, search within books, add bookmarks, highlights, and notes, look up terms, or place two documents side by side. It is designed for people who want a consistent reading workflow across several device types.

TagSpaces is an offline desktop application for browsing, tagging, searching, and managing local files on Windows, Linux, and macOS. Tags can live in filenames or sidecar metadata, while built-in tools handle notes, task lists, and common audio or video playback. Its browser extension saves web pages or screenshots locally, so the core workflow does not depend on a cloud service or internet connection.

ONLYOFFICE Desktop Editors is an open-source desktop suite for Windows, Linux, and macOS that works with documents, spreadsheets, presentations, PDFs, PDF forms, and diagrams without an internet connection. It supports Office Open XML files and can connect to cloud services for collaboration, while also offering signatures, password protection, plugins, and AI assistants. The project is licensed under GNU AGPLv3.

Chatd is a desktop application for asking questions about local documents with a Mistral-7B model. Document data stays on the computer, and the app bundles the local model runner so users do not need to assemble a separate stack. If Ollama is already running, Chatd reuses it; otherwise it starts and manages its own Ollama service. Users can simply download and run the executable, then optionally enable GPU support or choose another model.
