   An open-source, collaborative, WYSIWYG Markdown editor▲460

   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…

   OverType – A Markdown WYSIWYG editor that's just a textarea▲471

   Hi HN! I got so frustrated with modern WYSIWYG editors that I started to play around with building my own. The problem I had was simple: I wanted a low-tech way to type styled text, but I didn't want to load a complex 500KB library, especially if I was going to initialize it dozens of times on the same page. Markdown in a plain was the best alternative to a full WYSIWYG, but its main drawback is how ugly it looks without any formatting. I can handle it, but my clients certainly can't. I went down the ContentEditable rabbit hole for a few years, but always came to realize others had solved it…

   I made a tool to clean and convert any webpage to Markdown▲441

   My partner usually writes substack posts which I then mirror to our website’s blog section. To automate this, I made a simple tool to scrape the post and clean it so that I can drop it to our blog easily. This might be useful to others as well. Oh and ofcourse you can instruct GPT to make any final edits :D

   Textual Markdown – a Markdown “browser” in the terminal▲254

   Hi HN, This is a TUI app which displays interactive Markdown documents. Interactive in the sense that you can scroll code fences / tables / and click links. There's a Table of Contents extracted from the MD, and a very rudimentary browser like forward + back. I'm thinking it could be the starting point for a variety of hypertext like applications in the terminal. Very much a work in progress.
