Bear app developers announce Lettera, a beautiful Markdown editor for Mac

Shiny Frog has released Lettera, a native macOS Markdown editor currently in beta via TestFlight. Built on the engine powering Bear 2.0, Lettera allows users to open individual files or entire folders as workspaces, supporting the CommonMark standard with live WYSIWYG rendering and multi-format exports.

Why is Lettera being released as a standalone app?

Shiny Frog developed Lettera in response to user demand for the Bear 2.0 editor to exist as an independent tool. While Bear functions as a comprehensive note-taking ecosystem, Lettera focuses on a document-centric workflow. According to the developers, this allows writers, researchers, and developers to use the refined editor without the constraints of a database-driven note app.

The project stems from “Panda,” the 2021 codename for the Bear editor overhaul. That transition introduced a full switch to Markdown and the ability to hide syntax during writing, features that now form the core of the Lettera experience.

Pro Tip: Use YAML extensions in Lettera to add structured metadata to your documents. This makes your files more portable and easier to index across different Markdown-compatible tools.

What technical capabilities does the Lettera editor provide?

Lettera utilizes the CommonMark standard to ensure consistent rendering. Shiny Frog states the app employs a “What You See Is What You Get” (WYSIWYG) approach, where Markdown syntax disappears when the cursor leaves a line. This removes the need for a separate preview pane.

The editor supports several advanced formatting options:

Mathematical Notation: Integration with MathJax for complex formulas.
Rich Media: Support for inline images, attachments, and code blocks.
Structural Tools: Tables, footnotes, and a full Table of Contents outline for one-click navigation.
Export Options: Documents can be exported as PDF, JPG, ePub, HTML, or plain rich text.

Did you know? CommonMark was created to solve the “fragmentation” of Markdown. By creating a highly specified standard, it ensures that a document written in one editor looks the same in another.

How does Lettera’s file management differ from Bear?

The primary distinction lies in the storage architecture. Bear operates on a database model, where notes are stored within the app’s own system. Lettera, conversely, is a file-system editor. According to Shiny Frog, users can open a dedicated folder in iCloud or any local folder on their Mac.

This shift enables a “workspace” approach. Users can manage files and folders directly from a sidebar and open multiple documents in tabs. This architecture is designed for those building technical documentation systems or managing large-scale writing projects that require a traditional folder hierarchy.

What does this mean for the future of Markdown editors?

The launch of Lettera signals a trend toward “unbundling” productivity software. By separating the editor (Lettera) from the organizational system (Bear), Shiny Frog is catering to the “local-first” software movement. This movement prioritizes user ownership of files over proprietary cloud databases.

This approach mirrors a broader industry shift. Many professional writers are moving away from all-in-one apps toward a “best-of-breed” stack, where a dedicated editor handles the writing and a separate system handles the archiving. Lettera positions itself as the specialized tool for the actual act of composition.

Frequently Asked Questions

How can I try Lettera?
Lettera is currently available through Apple’s TestFlight app for beta testing.

Is Lettera a replacement for Bear?
No. It is a standalone editor. While it uses the same engine as Bear 2.0, it focuses on folder-based file management rather than Bear’s note-taking database.

Which Markdown standard does it use?
Lettera follows the CommonMark standard with additional support for Markdown extensions like YAML and MathJax.
