Built for the daily work of agents in Mallorca.
onProp.ai is the software for real estate agents in Mallorca: property research, property analysis, market reports for every municipality, holiday rental licences (ETV), purchase cost and tax calculation, contract review and drafting, and CRM integration — bundled into one platform, in English, German and Spanish. The demo videos deliberately show only short glimpses: behind every module is a full-fledged tool with far more depth than thirty seconds can show.
And the maths works out quickly: use the platform seriously just 2–3 times a month — one property search, one market report for an owner pitch, one reviewed contract — and it has already paid for itself. Everything beyond that is time won for what matters: selling.
Additional users included — everyone works with the same knowledge and the same tools.
Reports, PDFs and widgets carry your logo and your colours — not ours.
Report questions and issues via the support chat inside the platform — short paths and fast solutions instead of ticket queues.
All data comes from official sources, all answers from laws, decrees and regulations — continuously updated.
Access only for registered real estate agents — not a tool for private users.
Runs in the browser — no installation, no IT skills needed. You still get a personal walkthrough to start.
Every property screened before others even view it.
From an anonymous listing to a complete property file: parcel, surfaces, year built, licences — in seconds instead of trips to the authorities.
From listing to cadastral parcel — in seconds.
Listings hide the address — the Immofinder finds it. One link is enough, and you know which property is really behind the listing: location, cadastral reference and the key facts. What used to take local knowledge, phone calls and luck now takes a few seconds.
- Recognises fincas, villas and new builds — even with hidden GPS
- Shows existing ETV holiday rental licences on the parcel
- Jump straight to the cadastre and the property analysis
Property data & planning law at the push of a button.
Surfaces, year built, use, buildings, zoning: onProp.ai compiles the complete property file from official sources — and explains in plain language what is permitted on the parcel. Instead of trips to the authorities: solid answers before the client even asks.
- Official surface and building data instead of listing estimates
- Zoning and regulations explained in plain language
- As a PDF report with your logo for client meetings
Foreclosure auctions before word gets around.
Court auctions are a source of below-market properties — if you spot them in time. onProp.ai keeps an eye on the official announcements for you and presents all Mallorca cases clearly. You hear about opportunities before word gets around.
- Watchlist with status tracking per proceeding
- Cadastral reference, appraisal value and deadlines at a glance
- Updated automatically every day
The expertise of a whole team. In one chat window.
Taxes, planning law, licences, market data — specialised in Mallorca and the Balearics, always on the current legal status.
Your real estate expert. Around the clock.
ITP rates, Ley 4/2026, inheritance, rental law: the chat knows the legal situation in Spain, the Balearics and Mallorca — laws, decrees and regulations, always up to date. Upload escrituras, nota simple or land registry extracts — it summarises what they say and what to watch out for. And the same knowledge keeps working after hours: as a chat widget on your own website, it answers your visitors' questions.
- Specialised in Mallorca real estate — not a generic chatbot
- Answers based exclusively on laws, decrees and regulations — never on websites of agents, lawyers or tax advisors
- PDF analysis: escritura, nota simple, cadastral extracts
- As a widget on your website — in your branding
Market reports that win over owners.
Prices, transactions, trends: onProp.ai creates a well-founded market report for any municipality in minutes — the perfect tool for listing pitches and price negotiations with owners.
- Official transaction data and market statistics
- Fully formatted PDF in your branding
- Multilingual for international clients
All 17,000 holiday rental licences. One map.
Does the property have a rental licence? Which licences exist in the neighbourhood? The ETV map shows the complete official register — for many buyers the decisive purchase criterion.
- Search by town, signatura or property name
- Status, capacity and licence type per entry
- Linked to the cadastre and the Immofinder
Less risk, clearer numbers, faster signatures.
Contracts and closing costs are the stumbling blocks at the end of every transaction. onProp.ai clears them away.
A second pair of eyes — for every contract.
The contract check analyses Spanish real estate contracts clause by clause: what is unusual, what is missing, what puts your side at a disadvantage. Explained in plain language, with concrete wording suggestions.
- Arras, purchase, rental and holiday-letting contracts — risk rating per clause
- Briefing as a Word file — shareable with owner, gestoría and lawyer
- Makes you an informed negotiator — the legal review stays with the abogado
Upload the owner's stack. Know what's missing.
A new mandate, a folder full of PDFs and phone photos: escritura, nota simple, IBI, community minutes. The property file check reads the entire stack and matches it against the checklist for your property type — apartment, villa, finca or plot.
Your briefing shows: what's there, what's missing, what contradicts itself — and who needs to sort out what before marketing starts.
- Up to 20 documents per file — PDFs, photos or a single ZIP
- Finds contradictions: area mismatches, registered mortgages, expired certificates
- Every document with its Spanish original name and a translation
- Briefing as a Word file — shareable with owner, gestoría and lawyer
From a short form to a finished contract draft.
A few details about the property are all it takes — onProp.ai turns them into a cleanly structured Spanish contract draft, legally up to date and with Balearic specifics such as the IBAVI deposit already built in. You never enter your clients’ personal data: the draft works with placeholders you fill in comfortably in the Word document.
- Rental contracts under the LAU — long-term, second home or premium property
- Arras, opción de compra and compraventa
- Output as a Word document — ready to fine-tune with your lawyer
Purchase costs, accurate almost to the euro.
"What will this really cost me?" — the most common buyer question, answered instantly. The calculator knows the progressive ITP rates, all special schemes (under 36, familia numerosa, VPO) and applies legal changes like Ley 4/2026 correctly from day one.
- Buyer and seller side, resale and new build
- Result as a PDF for client meetings
- Also as a widget for your own website
So far: knowledge, numbers, certainty.
From here on: time.
The next modules clear the manual work out of your day — import, CRM, website.
Your CRM stays. The manual work goes.
onProp.ai doesn't replace your systems — it feeds them. onOffice1 and Propstack are directly connected.2
From listing to CRM. In two minutes.
Taking over a property means typing 40 fields, downloading 30 photos, translating the description. Or: pasting one link. onProp.ai takes over data, photos and features and creates the property fully prepared in your CRM — while you're already booking the next appointment.
- Idealista, Fotocasa and agency websites
- Automatic field mapping to your CRM schema

- Create tasks and activities on request
- Your data stays in your CRM
Your website joins the team.
Two onProp.ai modules can run directly on your own website — a service for your visitors and a lead magnet for you.
onProp.ai modules on your own website.
The chat module and the cost & tax calculator can be embedded directly into your agency website. Your visitors calculate purchase costs or ask questions — around the clock, on your site, under your name.

- Fully in your branding — your logo, colours and identity
- Texts fully customisable — you set the greeting and the tone
More than a dozen modules. And that's just the beginning.
onProp.ai grows with your daily work — whatever costs you time becomes the next module.
What's coming next.
onProp.ai is not a finished product that stands still: new modules are built wherever agents in Mallorca lose time. Next on the list:
- Verifactu invoicing — legally compliant invoices for agents, ready for the new obligation

- WhatsApp integration — enquiries and notifications right in the chat
- … and much more — requests from demos flow straight into the roadmap
