Beauty: Markdown editor for Mac, iOS and web with live preview.

What it does

Beauty is a Markdown editor available as a native Mac app, iOS app, and web application. The editor renders Markdown in place as the user types, so the formatted output appears live on the page rather than in a separate preview pane. It supports tables and other Markdown formatting elements. The browser version can be used without creating an account.

Who it is for

Beauty targets writers and developers who spend significant time in text editors and want visual feedback while writing. The tool appeals to people frustrated with existing writing applications who want Markdown rendering integrated directly into the editing experience rather than toggled between edit and preview modes.

How it stands out

The core differentiator is live in-place rendering. Instead of a split-pane interface with source on one side and preview on the other, Beauty renders formatting directly in the document as typing occurs. This removes the cognitive gap between seeing raw Markdown syntax and seeing the finished output. The cross-platform availability—Mac, iOS, and web—means users can switch between devices while maintaining a consistent editing experience. The web version's no-login requirement lowers the friction to trying the product.

What a founder should check

A competitor should validate three things. First, examine what established Markdown editors already do: Typora offers similar live preview on desktop; iA Writer and Bear compete in the writing app space; and various web-based tools like Obsidian, Notion, and HackMD have their own rendering approaches. Understand which incumbent features users actually depend on and which they ignore. Second, determine the switching costs for existing users. Many writers have years of documents, templates, and workflows built into their current tools. Check whether Beauty's cross-platform sync and data portability are strong enough to overcome that lock-in. Third, assess the technical moat. Live Markdown rendering is not particularly novel anymore—multiple editors have shipped this feature. The real question is whether the implementation, performance, or UI creates a meaningful advantage, or whether the market eventually commoditizes this capability across all editors.
