This project is an advanced web application designed to generate fast, accurate, and explainable project estimations by leveraging the combined intelligence of four Large Language Models (LLMs): GPT, Gemini, Claude, and DeepSeek. The platform allows users to submit project details—such as requirements, tech stack, scope, timeline expectations, and constraints—and then automatically processes the input through each LLM to produce separate estimations. The app aggregates these results and provides: Individual model estimations (time, cost, team structure, complexity level) Cross-model comparison Consensus estimation using custom logic Confidence scores Downloadable reports The goal is to help developers, agencies, and clients obtain data-driven and unbiased project estimates from multiple AI sources in one interface. Technology Stack Backend: PHP (Laravel), Node.js Frontend: React (MERN principles) AI Integration: API connections to GPT, Gemini, Claude, and DeepSeek Database: MongoDB / MySQL Deployment: Any cloud platform (AWS, Vercel, DigitalOcean, etc.) Key Features User authentication & dashboard Multi-LLM processing pipeline Parallel model execution for faster results Side-by-side estimation comparison Consensus algorithm for unified estimation Saved estimation history Export to PDF/CSV Admin panel for managing usage and API keys
