Neon Vision Editor

Native editing across Apple devices

A safer workflow for text, Markdown, and code.

For Markdown writers and developers, Neon Vision Editor keeps the useful parts of a lightweight editor: fast files, clear source, full previews, and shared documents that do not surprise you.

Hilthart Pedersen — the developer behind Neon Vision Editor.

Portrait of Hilthart Pedersen

I’m Hilthart Pedersen, known as h3p, and on GitHub as h3pdesign. I build Neon Vision Editor as an independent Apple editor for the space between a basic text editor and a full IDE.

The main addition in the newest direct macOS release is a plain-text-to-Markdown workflow.

A surprising amount of useful writing starts messy: copied notes, meeting material, rough outlines, older text files, or drafts with headings and lists that are only implied. Neon can now turn that into a reviewable Markdown proposal. It does not silently replace the original document; the point is to give you a structured starting point that you can inspect and accept deliberately.

On supported Macs, it can use Apple Intelligence. You can also configure another AI provider yourself if you prefer. I added cancellation, understandable feedback when a service is unavailable, and a timeout because an editor should never leave you guessing whether something is still happening.

The feature I am personally happiest with, though, is shared-file sync.

If you keep documents in iCloud Drive, a network folder, or open the same file in another app, it is easy for an editor to either miss external changes entirely or, worse, overwrite the work currently in front of you.

Neon now watches open documents for external updates. If a file changes elsewhere and the open tab is clean, it refreshes in place without making you close and reopen the tab. The editor preserves the useful context around that refresh: cursor position, selection, scroll position, and the current preview source.

New in v1.4.0

Large documents stay responsive without loading everything at once.

Neon’s macOS editor now works from the file on disk and keeps a bounded virtual viewport around the part you are editing. That avoids rebuilding a complete document buffer for each edit while preserving the normal editing workflow.

Download v1.8.0

Neon Vision Editor v1.4.1 macOS editor with line numbers, tabs, and compact toolbar controls

Edit, scroll, select, and save without a full-document rebuild.

The virtual viewport follows the scroll position and preserves the caret and selection when it replaces the active window. Syntax work and line layout stay limited to the visible range, keeping the editor focused on the work in front of you.

Encoding, line endings, external-change handling, and atomic saves remain part of the same file workflow. Files at 100 MB or more open as a clearly labelled, read-only partial preview for safe inspection.

The everyday editor

Start with the file in front of you.

Notes become documentation. A quick HTML edit needs a rendered check. A shared text file changes on another device. Neon is designed for these in-between moments, without turning the work into an IDE project.

01

Reviewable Markdown

Turn unstructured text into a Markdown proposal while keeping the original under your control.

02

Full source previews

Keep Markdown, HTML, and SVG source close to the rendered result instead of switching apps.

03

Safe shared files

Refresh clean documents from iCloud Drive, network folders, or another app without replacing unsaved work.

New in v1.2.1

A clearer toolbar for every Apple device.

Version 1.2.1 adds platform-optimized toolbar presets with compact symbols and consistent controls across macOS, iPadOS, and iOS. Configure standard, focused, developer, review, or complete workflows from Settings, while iOS keeps its transparent status-bar composition.

Choose the tools you need without losing the document.

Compact labels keep macOS and iPadOS toolbars readable, while iPhone stays icon-first where space is limited. Presets make it easier to switch between everyday editing, focused writing, development, review, and the complete workspace.

The release also restores the transparent iOS status-bar and navigation-surface composition without changing the existing editor or preview layout.

Stable iOS surfacesKeep the transparent status-bar composition and existing layout.

New in v1.2.0

Bring PDFs and project files into the same review workflow.

Version 1.2.0 expands Neon beyond source files and Markdown. PDFs and PNGs can now become part of a responsive project overview, while PDF highlights and attached Markdown notes keep research connected to the document you are reading.

Download v1.8.0

Read, mark up, and keep the explanation beside the source.

Highlight a passage in a PDF, attach a Markdown note, and return to the same review context later. Project cards make Markdown and PDF documents easier to scan, while expensive artwork loads only for the cards that are visible.

On iPhone and iPad, double-tap a tab to close it without interrupting the existing unsaved-change protection. The result is a more deliberate workspace for research, documentation, and mixed-format projects.

From rough notes to useful structure

Make Markdown a proposal, not a destructive rewrite.

Copied notes, an old text document, or a rough outline often already contain the structure you need. Neon can turn that into a Markdown draft for review rather than silently changing the source.

Keep the judgment with the writer.

On supported Macs, Markdown conversion can use Apple Intelligence. A separately configured provider can also be used when that is your preferred workflow. Either way, the result remains a proposal: you review the headings, lists, spacing, and emphasis before deciding what belongs in the document.

Cancellation, a clear unavailable state, and a safety timeout are part of the workflow. An editor should never leave you wondering whether a background action is still working.

New in version 1.0.2

A focused AI assistant, built into the editor.

Ask about the current file, project structure, or a selected snippet without leaving Neon. Responses stay in a saved, reviewable conversation, with Markdown formatting and syntax-highlighted code kept readable.

Markdown-first answersHeadings, lists, inline code, and wrapped code blocks remain structured and readable.
Explicit contextChoose a selection, current file, project structure, or no document context before sending.
Private by defaultAI requests are opt-in and credentials stay in the existing secure storage flow.

External changes should refresh safely, not overwrite work.

Documents kept in iCloud Drive, network folders, or another app can change while they are open. Neon watches for those changes and refreshes clean tabs in place—without forcing you to close and reopen the file.

It preserves the context that matters: the current cursor, selection, source viewport, and preview source. If you have unsaved edits, Neon does not replace the buffer. The existing review choices remain yours.

1

Clean tab: refresh the updated file in place.

2

Unsaved changes: keep the local version protected.

3

Review deliberately: choose Keep Local, Reload from Disk, or Compare.

Preview Markdown, HTML, and SVG where you write.

Markdown is not an afterthought in Neon. On Mac and iPad, a full preview can sit beside the source document; on iPhone, it opens as a focused reading view. The formatting controls remain with the editor, below document tabs, without covering the preview or a project sidebar.

HTML and SVG preview follow the same idea: edit the source, then see the output without leaving the file workflow. It is less about publishing polish and more about getting a reliable visual answer while you work.

See your Markdown project at a glance.

Markdown card previews turn a folder of documents into a calm, useful overview. Scan titles, paths, excerpts, file sizes, heading counts, images, file status, sorting, and the active-document indicator before opening the document you need.

A project overview beside your preview.

When a project grows beyond one document, the card panel keeps the surrounding context visible. Choose a responsive grid or a focused stack, place it beside the Markdown preview, and select a card to focus the existing editor tab.

Cards stay lightweight and reviewable: bounded excerpts, heading counts, local image thumbnails, and clear status labels help you find the right file without opening a second editor or changing the source.

Editor evolution

Four releases, one more dependable editor.

Each release builds on the last: protecting shared work first, then making the editor more deliberate, restoring windows reliably, and hardening the document transition that ties the interface together.

Completes macOS 27 release readiness while keeping existing deployment targets and runtime availability checks for older systems.
