Energy France is a free home energy diagnostic built for households in France. Answer a few simple questions about your home and energy use, and get a personalized ranking of where to look first: electricity & gas, heating, or solar. No account, email, or phone number required. This is an early prototype, and we're launching it to learn from real users and improve the recommendations.
What became possible in your product with Astra that was not practical before?

GPT-6 Astra made it practical for me to turn Energy France from an idea into a working, instrumented public prototype in a very short iteration cycle. It helped across the end-to-end build workflow: reasoning through product requirements, implementing and reviewing the diagnostic experience, adding privacy-conscious funnel analytics, testing the implementation, and deploying iterations while preserving the existing deterministic scoring logic. Instead of using AI as the consumer-facing decision engine, I used Astra as an engineering and product-building agent to accelerate the path from concept to a measurable real-world experiment.

Hi Product Hunt! 👋
I built Energy France around a simple question: when a household feels its energy costs are too high, where should it look first?
Instead of immediately pushing an offer, the prototype asks a few questions about the home and energy usage, then ranks three possible areas to explore: electricity & gas, heating, and solar.
The project is still at an early validation stage. There is currently nothing to buy, and the diagnostic doesn't ask for a name, email, or phone number.
What I'm looking for most from this launch is feedback: Was the diagnostic easy to complete? Did the ranking make sense for your situation? And what would make the result genuinely more useful?
Thanks for testing it — critical feedback is very welcome.
