A native markdown and code editor for Apple platforms

Neon Vision Editor is a Swift app for editing markdown, notes, and code across macOS, iOS, iPadOS, and visionOS, focused on fast startup and a minimal editing surface.

Editing and navigation

The editor targets fast, low overhead editing rather than a full IDE. It opens regular and large text files with tabbed editing, keeps files below 100 MB editable, and switches to a Large File Mode that favors responsive scrolling and typing by deferring heavy work. Syntax highlighting is Swift 6 ready and covers TeX or LaTeX and Typst, with regex find and replace and an optional code minimap for click to jump navigation. Navigation uses Quick Open with Cmd+P, a project sidebar combining Files, Search, Git, and Terminal, and an indexed find in files that stays open during edits.

Preview and output

Markdown, HTML, SVG, PDF, and PNG previews stay integrated with the editor, and Markdown can export to paginated or single page PDF. The version 1.5.1 release added distinct Plasma and Deep Ocean palettes and strengthened several existing themes, reaching 25 theme palettes with custom options and live preview and export CSS parity. A code snapshot feature shares source excerpts as images using ten themes, gradient or transparent backgrounds, and configurable export sizes. Plain text can be turned into validated JSON through an explicit AI assisted action.

Platform and safety

Neon Vision Editor runs on macOS, iOS, iPadOS, and visionOS, with iCloud sync for appearance and themes. The README states the app has no telemetry. A safe mode helps with startup recovery, and files of 100 MB or larger open as a clearly marked, read only Partial Open of the first 4 MB, ending at a line boundary where possible, and it never lets the partial content overwrite the source. The macOS build adds an optional nve command line helper linked by the user into the home bin folder.

Editorial conclusion

Neon Vision Editor is written in Swift, licensed under the Apache 2.0 license, and is distributed through GitHub Releases, the App Store, TestFlight, and a Homebrew cask.
