What it does
CleanMark is a Chrome extension that extracts clean Markdown from ChatGPT, Claude, Perplexity & websites. Perfect for prompt engineers, writers, & devs. Bonus: Markdown cheat sheet +md prompt pack. No ads. No tracking. Just clean content.
🚀 Why CleanMark?Copying from the web usually gives you ads, sidebar links, tracking scripts, and broken formatting. CleanMark uses Mozilla's Readability engine (the same one in Firefox Reader View) to strip the noise and give you pure, high-quality Markdown.🧠 AI-Ready Content Structured Output: Get clean H1-H6 tags, lists, and code blocks that LLMs love. AI Copy Mode: Automatically prepends sour

I made a tool to clean and convert any webpage to Markdown2024 · markdowndown.vercel.app · ▲441My 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.

I was the main contributor to workout.lol, an open-source fitness app to easily build a workout routine.
