I’m Julien, the builder behind AnnoncIA. I got the idea after talking to several small real estate agencies in France. Each agent was spending 20–30 minutes per property just writing listings — and then rewriting them for each portal because SeLoger, LeBonCoin, and PAP all have completely different styles and audiences. So I built AnnoncIA: you enter the property details once, pick the portal, and get a polished, publish-ready listing in under 30 seconds. The AI adapts the tone, length, and structure automatically. What makes it different from just using ChatGPT: ∙ Portal-specific rules baked into every generation (SeLoger ≠ LeBonCoin ≠ PAP) ∙ No prompt engineering needed — it just works ∙ Secure backend: the API key never touches the browser ∙ Built specifically for French real estate vocabulary and portals The product is live at annonc-ia.com — I’d love your feedback, especially from anyone in real estate or PropTech.
