Description
Project Cost Calculator is a Next.js lead-generation and estimation tool built for software companies. It guides users through selecting project type (AI/ML, mobile app, web app, or blockchain), scale (MVP to enterprise), and a detailed project description. The app then uses an OpenAI LLM to generate a list of feature modules from the description; users select which modules to include, and the system calculates budget, timeline, and developer cost per module before submitting the lead.
Contact verification is handled via email verification and Twilio SMS for phone numbers, ensuring qualified leads. After submission, the company receives the lead and the user gets confirmation by email and WhatsApp. The flow is designed to be SEO-friendly and conversion-focused, with clear steps and semantic structure for discoverability.
The stack is Next.js with TypeScript and React on the front end, integrated with OpenAI for module generation and Twilio for SMS verification. The tool is responsive, accessible, and built with performance and search visibility in mind.
