Antalogy

Antalogy is a native desktop word processor for Markdown. It pairs plain-text .md files with a Microsoft Word–style ribbon, so documents can be formatted with toolbar buttons instead of memorized syntax. Each document opens in its own native window, and files stay on the local drive with no account, cloud backend or telemetry.

It imports and exports .docx files while keeping styles, images and tables, converting embedded EMF/WMF images to PNG where possible. Mermaid code blocks render as live diagrams in the editor and are exported to Word as high-resolution images. Built-in navigation and search help move around long documents.

An optional AI assistant, disabled by default, connects to local or remote OpenAI-compatible LLMs such as LM Studio, Ollama, Lemonade Server and Unsloth Desktop, with multiple profiles and localhost autodiscovery, and can sync the whole document or a selection into the chat. Antalogy is built with Go and Wails rather than Electron, is free for personal and commercial use, and runs on Windows, macOS (Apple Silicon) and Linux.
