Three cases as your staff would experience them. In the real application every answer is generated on your documents and questions — these examples are frozen for the demonstration, but the figures and articles cited are the real ones (Finance Act 2026 reference).
Real recording of the interface: login, an inheritance computation, the analysis of a sale agreement uploaded as PDF, a dismembered gift, then the office's activity dashboard.

In short: €100,000 child allowance, 20% bracket on the €150,000 taxable base, ≈ €28,194 due — then three things to verify (gifts within 15 years, the 20% main-residence allowance, life-insurance capital outside the estate) and the 6-month filing deadline.
Promesse synallagmatique de vente (compromis) sous seing privé — maison à usage d'habitation avec jardin, « 12 rue des Tilleuls » (commune fictive), prix de 285 000 € dont 8 000 € de mobilier listé en annexe.
In short: a six-part structured summary — nature and object, parties (with a flag on unmarried buyers purchasing in undivided co-ownership without an agreement), key terms, deadlines (10-day withdrawal, 2-month pre-emption purge), points of attention, missing documents. Processed in memory, never stored.

| Valeur en pleine propriété | 400 000 € | — |
| Usufruitier de 65 ans → usufruit 40 % / nue-propriété 60 % | NP = 240 000 € | art. 669 CGI |
| Abattement enfant (si non consommé — rappel 15 ans) | − 100 000 € | art. 779 I CGI |
| Base taxable | 140 000 € | — |
| Barème ligne directe, tranche 20 % | 140 000 × 20 % − 1 806 € | art. 777, tableau I |
| Droits dus | ≈ 26 194 € | référentiel 2026.0 |
In short: at 65 the usufruct is valued at 40% (art. 669), so bare ownership = €240,000; minus the €100,000 allowance, 20% bracket, ≈ €26,194 due — and no further duties when the usufruct ends (art. 1133), which is the point of the operation.
Who uses the tool, how much, how fast — by metadata only: the content of questions and documents is never recorded. That is the counterpart of "zero storage": you steer usage without ever exposing the files.

The file name of analysed documents only appears if the office enables it in the settings — off by default.
