The Bear Team Releases Public Beta of Lettera, a New Mac Markdown Editor

Today, the team behind note-taking app Bear announced the public beta of Lettera, a new Mac text editor, based on Panda, an earlier beta that was used to work out the Bear 2.0 text editing engine. That immediately caught my eye because I’ve been using Panda for months. In fact, it’s the default way I open Markdown files now.

What drew me to Panda was the automation work I’ve been doing with agents. I use the Superpowers plugin (which got an excellent 6.0 update this week) with both Codex and Claude Code, which generates plans, design documents, and specs as part of its process. Panda turned out to be a great way to read those documents because the Bear 2.0 UI is excellent, and with Panda, I could open any Markdown file as a standalone document that didn’t require importing it into Bear itself.

According to the Bear team’s post today, Lettera is designed to preserve Panda’s simple approach to Markdown files and extend it to the Mac’s file system:

Lettera works around your setup. Open a single file to read and edit it, or open a folder as your writing workspace…

That way, Lettera can be used as your default Markdown editor no matter where Markdown files are saved, which is how I’ve been using Panda, or as a text editor with a dedicated folder of working files in iCloud, which is a departure from Bear, which hides the file system from users. Other features will be familiar to anyone who has used Bear before, including its excellent Markdown rendering, versioning, a table of contents sidebar, and support for multiple export formats.

I’ve only just scratched the surface of Lettera, but I was already a fan of the more limited Panda, so I expect Lettera to quickly become the text editor I use for any writing that isn’t an article like this one, for which I’m still using Obsidian, thanks to its extensive plugin catalog.
