Show HN: I built a Markdown to HTML converter that fixes AI-generated quirks

Hi HN,

I built a free Markdown to HTML converter that solves a pain I kept running into with AI-generated content.

For years, I relied on tools like ChatGPT and Claude to draft blog posts, but the Markdown they produced often broke existing converters. Instead of standard `` or `-` for lists, I'd get odd symbols like `:` or `•`. The converter would fail, leaving me to manually fix formatting every single time. It was frustrating and time-consuming.

So I decided to build my own: *[Markdownhtmlgen.com](https://markdownhtmlgen.com)*.

Key features: - Converts Markdown to HTML that actually works with AI-generated quirks - One-click emoji removal - Auto-IDs for headings (great for anchor links) - Adds `rel="noopener"` to links for better security - Runs entirely in the browser, no backend or registration required

I originally built it for myself, but it’s been saving me hours of editing, so I thought it might help others too.

I’d love feedback from this community: what works, what doesn’t, and what features you’d want in a Markdown converter.
