Leasing Advisor

Start from your vehicle and budget, adjust a monthly estimate, and ask an assistant about documents and EV benefits.

The real Leasing Advisor application interfaceTry the demo

Estimates are illustrative, not an offer or approval. Please confirm terms with the leasing provider.

How it's builtNext.js, React, TypeScript, Python, FastAPI, OpenAI

A rule-based calculation service in FastAPI computes payments and document checklists, so the numbers stay consistent. An AI assistant answers follow-up questions using your current offer and cites sources from the Green Leasing Assistant. If the AI is unavailable, built-in fallbacks keep the demo working, and provider keys stay on the server.
