Who owns a given parcel, what a company owns across France, what local zoning rules allow, what an operation would yield — on open data, with deterministic calculation and a source behind every figure.
TOISE now has its own website. Platform, ChatGPT/Claude connector and second opinion on investment files: visit toiseai.com.
Go to toiseai.com →Land registry, recorded transactions, company registry, zoning: each source lives on its own public portal, with its own interface and its own format.
Identifying who owns a parcel, or everything a company owns nationwide, means cross-referencing these databases by hand — hours of work for a single question.
A yield or valuation often circulates without ever showing the calculation method or the source of the underlying data.
TOISE aggregates land registry, recorded transactions, the company registry and zoning rules from French open data, and answers ownership, zoning and operation-feasibility questions in natural language. Every answer states its source and its calculation method.
Web platform — direct search on toiseai.com.
ChatGPT / Claude connector — query TOISE directly from your usual AI assistant, no need to switch tools.
Alongside the platform, get an independent, uncompromising human analysis in 5 to 10 business days answering a single question: does this deal hold up, and at what real price?
Line-by-line financial analysis.
Simulating vacancy or the loss of a key tenant.
Debt and waterfall modeling.
CDAC/AEC, diagnostics, fire-safety compliance (ERP).
Alongside the data engine and Second Opinion, TOISE is preparing a B2B listings platform for commercial property — retail units, retail parks, shopping galleries, offices and logistics warehouses. No listing is published yet: the catalogue will open with our distribution partners. The sourcing tools are already available and built on public data (company registry, land registry, recorded transactions, zoning).
Search by region, asset type, surface area and budget, with a map: when the catalogue opens.
Planned at launch: general location openly available, detailed data released after qualification and NDA.
Company search, cadastral parcels, recorded transactions and zoning rules.
