what is editxr fr?

editxr is a Markdown editor that runs inside a terminal window. It shows a rendered view directly in the terminal, meaning headings, lists, tables, and code blocks are styled in place as you type. The line your cursor is on stays as raw Markdown text so you can edit it, while everything else around it is rendered. There is no split-screen preview pane. An optional AI editing mode lets you highlight a section of text, type an instruction like "make this shorter" or "rewrite this as a numbered list," and see the proposed change as a color-coded diff before deciding to accept or reject it. This avoids any situation where AI changes are applied without your review. The tool supports local language models through LM Studio, OpenAI, OpenRouter, or an offline placeholder that needs no network connection at all. The editor is written entirely in Swift and has no external software dependencies, so it starts quickly and handles large files without slowing down. Prebuilt binaries are available for macOS (both Apple Silicon and Intel) and Linux (x86_64 and ARM), and the Linux versions are statically linked, meaning they work on any Linux distribution without needing a Swift runtime installed. It can also be installed via Homebrew. Additional features include multi-file tabs, navigable links in Obsidian-style wikilink format, 12 built-in color themes with light and dark options, an incremental search, and HTML export that opens the rendered document in a browser. Settings such as theme, AI provider, and per-file cursor positions are saved in a local config file.
