Ai Context Purifier

Copy any webpage as clean Markdown — no ads, no nav, no noise. Perfect for AI prompts and LLM context.

---

AI Context Purifier strips away everything you don't need — navigation, headers, footers, ads, sidebars — and converts the remaining content into clean, readable Markdown. One shortcut, and you have exactly what you need for your AI prompt.

How it works
Select text on any webpage (or select nothing for the full page), then press ⌘⇧X (Mac) / Ctrl+Shift+X (Windows), or right-click → "Copy as Clean Markdown". The clean Markdown is instantly copied to your clipboard — ready to paste into ChatGPT, Claude, Gemini, or any other AI tool.

Why it matters
Pasting raw webpage content into an AI wastes tokens on navigation, cookie banners, and unrelated sidebar content. AI Context Purifier removes the noise so the AI gets only the signal.
