iA Writer

iA Writer is a plain‑text editor that centers on Markdown writing, offering a minimal interface that removes visual distractions such as toolbars and pop‑ups. Its Focus Mode highlights the current sentence or paragraph while fading the rest of the document, helping users maintain a continuous flow of thought. The editor tracks typed versus pasted text, providing visual cues that distinguish original content from inserted material.

The application includes editor tools inspired by code editors, notably Syntax Highlight, which reveals sentence structure and potential blind spots, and a Style Check feature that flags clichés, fillers, and redundant phrasing. These utilities are designed to encourage writers to refine their prose without imposing automatic corrections.

Available across macOS, Windows, iOS, iPadOS, and Android, iA Writer synchronizes a consistent writing experience on multiple devices. It targets writers who value simplicity, plain‑text portability, and focused editing over the extensive feature sets of traditional word processors.
