Real file tree: create folders + files, rename, delete. Command palette: press ⌘⇧P (Mac) / Ctrl⇧P (Windows/Linux). Smart paste: paste rich HTML and get clean Markdown. Live preview: split-pane preview with scroll sync. Extras: optional Mermaid diagrams + KaTeX math.

A local-first Markdown editor with file management, intelligent paste, and split-pane preview.

LocalMark Studio helps you write and organize Markdown with a real file tree, a command palette, smart paste from the web, and a split-pane preview with scroll sync. Folders, files, rename, delete — organized like a real project. Everything is stored locally in your browser (IndexedDB) — great for drafts, notes, and private writing. Toggle math support for LaTeX equations rendered with KaTeX. Import Markdown/text (or HTML → Markdown). Export as MD, HTML, PDF, or JSON metadata. Organize notes like a project: nested folders, rename, delete, and quick navigation. Use the command palette to toggle preview, themes, and Markdown features.

    Inspired by the design and UI/UX of apps like Notion, and utility of open-source apps like StackEdit, I decided to create a minimalistic, local-only WYSIWYG Markdown editor. Some features worth highlighting: - Monaco editor and Prettier integration for code snippets - Tables (apparently the holy grail of WYSIWYG editing) - Embeds (for CodePen, CodeSandbox and YouTube, most useful for HTML or JSON exports) - Accepts Markdown paste-in, and "exports"/generates HTML, Markdown and JSON outputs - Collaboration (with real-time awareness and initial commenting system, available only when…

    Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself.

    Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
