Most markdown editors are just a text box. This one feels like a lightweight Notion + Obsidian but private. Organize your notes with a multi-document sidebar, write in clean markdown with a live preview, and visualize ideas with built-in Mermaid diagram support. Everything is stored locally, nothing ever leaves your browser. No login, no account, no cloud. Just a fast, private scratchpad that's ready the moment you open it. Perfect for quick notes or just using as scratchpad compatible with LLMs
