The web rendered for you.
Enter any URL and this tool fetches the page, strips it down to its content, and asks an LLM to rewrite it with your preferences applied.
The web was supposed to be for the reader. Early browser proposals imagined user agents that would present content however you wanted. HTML described meaning, and your browser decided how to show it.
That vision didn't last. Designers wanted control and CSS came to be. LLMs are one way to make it possible.
This runs on fast, affordable models. Pages would look significantly better with larger models but that would be slow and expensive.
