keinsaasforever/better-chatbot — reverse-engineered prompt

I want an open source AI workspace that feels like a better ChatGPT for me and a small team. Build a polished web app where I can chat with different AI providers from one place, switch models easily, and use helpful tools inside the chat like web search, code execution, charts, and MCP servers.

I also want custom agents I can create with their own instructions and tool access, plus simple visual workflows that can be saved and called from chat like tools. Please include image generation, realtime voice chat, file uploads if the app supports them, and easy sharing for chats, agents, workflows, and MCP setups.

The chat experience should feel fast and intuitive, especially with @ mentions to call tools, agents, or workflows without extra setup. Make it work locally first and also be easy to deploy online with minimal setup, ideally needing just one AI API key to get started. If anything is unclear, check the current docs online and wire up the sensible defaults.
