usualdork/EndlessClaude — reverse-engineered prompt

Build me a simple single page web app that feels like a clean dark mode Claude chat client. I want people to open it and start chatting right away with no signup screen, no API key screen, and no complicated setup.

The app should have a Discord inspired layout with a sidebar for multiple chats, a main message area, and a bottom input box. Make it work nicely on phones too, with the sidebar collapsing and the chat taking up most of the screen. Save chat history in the browser so conversations are still there after refreshing. Users should be able to create chats, delete chats, clear conversations, copy messages, and see streaming style AI replies.

Use plain HTML, CSS, and vanilla JavaScript if possible, with Bootstrap and Font Awesome for the UI. Connect it through the Puter API for Claude access. Please keep the design polished, responsive, touch friendly, and ready to deploy as a static page.
