u14app/deep-research ? reverse-engineered prompt

Build me a web app for deep research that can take a topic, search the web, and turn it into a clear research report in a couple of minutes.

I want it to work with different AI models like Gemini, OpenAI, Anthropic, DeepSeek, Grok, and Ollama, and let me plug in my own API key and base URL if needed. It should keep my data local in the browser, save research history, and let me reopen and refine past reports later. I also want file upload so I can add PDFs, office files, and text files as a private knowledge base.

Please include a clean modern interface where I can edit the final report, change the reading level or length, translate the full text, and generate a knowledge graph. It should support web search providers too, and work as a PWA. If possible, make it deployable to Vercel or Cloudflare, and expose an SSE API plus MCP server so other tools can use it. Look up current docs online if you need to.
