what is pepite fr?

Pepite is an open-source Chrome extension for people shopping for property in France. When you open a real estate listing on sites like Leboncoin or SeLoger, the extension overlays a price score directly on the page, comparing the asking price to actual recorded sales in the same area. These comparisons use DVF, a French government database of real property transactions, so the reference data is from real sales rather than other listings. Beyond the price badge, the extension generates a detailed report. This covers the price per square meter against local medians, the total acquisition cost including notary fees, neighborhood amenities pulled from OpenStreetMap (schools, shops, health services, transit, green spaces), flood and natural hazard risks from the French government's Georisques database, the local rental market, and local tax rates. A weighted score combines these factors into an overall assessment. If you add an AI API key (Gemini, Claude, or OpenAI), the extension runs a full AI analysis of the listing. This produces a written summary, points to watch out for, a negotiation price range with supporting arguments, a visit checklist, and separate opinions for four buyer profiles: primary residence, traditional rental, short-term rental, and house sharing. It also generates three draft negotiation emails (assertive, moderate, or friendly) that you can copy and send. A separate AI feature lets you select a photo from the listing and have it redesigned in a chosen interior style, with a cost estimate for the work. All data processing happens inside your browser. No data is sent to any server operated by the project. Your API keys are stored locally in the browser and are only used to call the AI provider you choose. The extension is not yet on the Chrome Web Store, so installation requires loading it manually in developer mode using a zip file from the project's releases page. The README notes this is a personal project intended as a decision support tool, not investment advice.
