thecynetx/freeclaude ? reverse-engineered prompt

Build me a clean dark mode AI chat app that feels like ChatGPT and Claude in one place.

I want a simple web page where I can sign in with a free account, pick from a few different AI models like Claude, GPT 4o, DeepSeek, and Gemini, then start chatting right away without needing my own API keys or credit card. The chat should support long conversations, show message history nicely, and save everything in the browser so it is still there when I come back.

Make it easy to run locally with a small server that just serves the site, and keep the whole thing private and lightweight. I’d also like markdown rendering for replies, a nice sidebar for past chats, and a polished responsive layout that works well on desktop and mobile. If you need current docs for the AI connection, look them up online and wire it up in the simplest working way.
