Urbain: your AI expert on French local urban plans – PLU and PLUi
Urbain is an AI assistant dedicated to French local urban plans (PLU) and their inter-municipal equivalents (PLUi), the documents that set zoning and building rules for every plot of land in France. It answers technical questions in natural language, down to the parcel level, and links each answer directly to the relevant section of the regulations.
Designed for local authority planning departments that review building permits, consulting firms, notaries and property developers, it supports professionals who extract and interpret regulatory constraints from dense documents every day. Urbain doesn’t replace urban planning and real estate experts: it frees up their time to focus on analysis, consultation and decision-making.

Urban Planning Documents: A Daily Challenge
Dense, technical regulations
A local urban plan (PLU or PLUi) runs to several hundred pages: written regulations, zoning maps, planning and development guidelines, and public utility easements. Assessing the rules that apply to a single parcel means cross-referencing these heterogeneous, scattered sources.
Time-consuming analysis
Reviewing a permit application, issuing a zoning certificate or assessing a project’s feasibility calls for both textual and spatial analysis at the parcel level, along with regulatory calculations, often under tight deadlines. This work is hard to standardize from one project to the next and demands significant expertise.
Reliable, shareable answers
An answer on zoning rules commits the responsibility of the local authority or professional who gives it: it must be backed up clause by clause. It must also be clear to non-specialists, such as elected officials, property developers and partners.
