Meet Lenny
Lenny is a little screen with a job. He opens the file, shows you the page, and gets out of the way. That is the whole personality, and it is the whole product.
He turns up on the icon, and nowhere you are trying to work.
Your iPhone won’t open an HTML file like a normal page. HTML Lens will. Paste it from ChatGPT, Claude, Gemini, or anywhere else, and see the real page.
