About Numeralis
Clearer information for new-build property decisions.
Numeralis organises information about new developments and units in Portugal so prices, areas, availability and delivery timelines can be compared clearly. Technology accelerates the work; responsibility for what we publish remains ours.

What we do
We turn scattered information into a comparable dataset.
Buying in a new development means comparing information that arrives in different formats and changes over time.
Numeralis structures that information in one consistent format. This makes it possible to assess entry price, price per square metre, position against the area, units indicated as available and expected delivery.
When a figure is unconfirmed, we say so. Missing information is not replaced with an estimate presented as fact.
How we work
From available information to a useful comparison.
We apply the same process to information entering Numeralis, regardless of the development.
- 01
We gather information
We start with information supplied or made publicly available about developments, units and the market.
- 02
We structure the data
Data and artificial-intelligence tools help identify, organise and connect prices, areas, unit types, availability and timelines.
- 03
We cross-check and validate
We check consistency, provenance and freshness. Conflicts or unconfirmed fields are flagged rather than presented as certain.
- 04
We show the context
We present each project and unit in a comparable format, with area references and enough context to support an informed decision.
Sources and technology
AI supports the research. It does not replace validation.
Numeralis uses artificial-intelligence tools and providers—ChatGPT (OpenAI), Claude (Anthropic), Gemini (Google), Grok (xAI), Llama (Meta), Mistral and Perplexity, including others—to support research, data processing and information comparison. These tools may contribute to collecting and structuring our dataset, but they are not treated as sole authorities or final confirmation.
An AI-generated response is never published as verified fact on its own. Numeralis cross-checks the available information, retains its source context and flags what cannot be confirmed. Use of these tools does not imply a partnership, sponsorship or endorsement by their providers.
Principles
What guides every item we publish.
Visible uncertainty
When availability, price, timing or terms are unconfirmed, we make that limitation clear.
Independent comparison
Paid positions do not alter metrics, area references or the way projects are compared.
Accountability
Found something that needs reviewing?
Property information changes. If you spot a discrepancy or need to confirm a detail before deciding, contact us. We are based in Porto and work across the Portuguese market.
