Hi all — I'm the developer of Folding Mirror (foldingmirror.app), an
independent Markdown editor for macOS.
The short version: it's a WYSIWYG-style Markdown editor in the vein of
Typora, but built on CodeMirror 6, and with an AI agent that can actually
operate on your files and the app itself.
Before anything else: there's a running copy of the editor on the front
page of the site(simple version).
What's in it:
• Live preview — you type Markdown, you see the result, in the same
place. Put the caret on a line and it folds back to source.
• Plain files. Your notes are .md on disk in a folder you chose. No
proprietary database, no sync account, nothing to export out of.
• A built-in agent with MCP/Skills support — it can read and edit files in your
vault, draw diagrams, and change app state. Writes go through an
approval card; nothing is written behind your back.
• Excalidraw drawings and Mermaid diagrams embedded in documents.
• A graph view over the links between your notes.
• Version history backed by git, in a separate gitdir — it never touches
a repo you already have in that folder.
Pricing: one-time purchase, no subscription. $25.90 for 3 devices,
including 12 months of updates (the app keeps working forever after
that). 14-day trial, no account needed. Currently $14 during the launch
window.
macOS 12+, Apple Silicon and Intel.
Happy to answer anything, and genuinely interested in feedback — a lot of
what's in here came from people telling me what annoyed them about other
editors.
