Hey everyone! Today is a day we have been quietly looking forward to for a while, and we are thrilled to finally say it out loud: Lettera beta is officially here! ๐
Lettera started its life as Panda, the code name for the new editor we built for Bear 2.0. During that process, so many of you asked whether this editor could live on its own as a standalone app. So here we are.

What is Lettera?
Lettera is a native, refined Markdown editor for macOS. Built for writers, researchers, developers, and anyone who works with documents, from a quick blog draft to a complete technical documentation system.
Lettera works around your setup. Open a single file to read and edit it, or open a folder as your writing workspace:

๐ Folder as workspace Lettera opens your iCloud Lettera folder by default. To work with your own folders, go to File > Openโฆ or drag any folder from Finder onto Lettera in the Dock. Your full folder structure appears in the Sidebar, exactly as it lives on your Mac. Click any Markdown file to open it in the editor and start editing.
๐ Single file editor You can open any Markdown file directly on your Mac in Lettera with editor-only view to get straight to work.
What Lettera can do
- Write in WYSIWYG Markdown Lettera follows the CommonMark standard with live rendering. Markdown syntax hides when you are not editing, so you can write and preview in one place. A BIU formatting bar is also available for quick styling
- Format with rich styles, tables, quotes, lists, code blocks, inline images and attachments, Math formula with Mathjax, and more
- Share and export Copy your writing as plain text, rich text, Markdown, or HTML. Export to PDF, JPG, ePub, and more when it is time to send your work somewhere
- Manage files and folders directly from the Sidebar without leaving the app. Open files in tabs to work across multiple documents in one place. Image files can be previewed right inside the editor
- Table of Contents Navigate your document with a full outline, and jump to any section in one click
How to get it
You can download Lettera Beta through TestFlight below.
Feedback welcome!
All these features need lots of testing, and we would love your help. You can start by editing this file, or create a new one by clicking โ in the Sidebar. You can also open any folder you are already working on, click any Markdown file, and pick up right where you left off.
