Build Multi-LLM AI Comparison Platform (Like AI Fiesta

I need to build a platform where users can: Write a single prompt Get responses from multiple AI models (ChatGPT, Claude, Gemini, Groq) at the same time See all responses side-by-side Save chat history Think of it like AI Fiesta (aifiesta.ai) but for my education platform. What I need to know from you: Can you build this? How long will it take? What's your detailed technical approach? Are you available for a meeting to discuss this? If you're interested, please reply with your answers above and your portfolio links. Looking forward to hearing from you.
