Source-backed planning AI is becoming the new trust baseline

Planning analysis is only useful when the user can see the policy, decision record, map layer, and source date behind the answer.

The output is not enough

Planning users do not just need a confident answer. They need to know which official source supports the answer, whether the source is current, and whether the conclusion is a confirmed fact or a professional inference.

That distinction matters across simple home extensions, commercial redevelopment, derelict-property reuse, and appeal strategy. A model can summarise quickly, but the product has to expose the evidence trail.

Evidence packs reduce risk

Planeer is moving every major planning answer toward an evidence-pack pattern: source cards, policy references, precedent counts, GIS evidence, and visible context usage. That gives homeowners and professional teams a practical way to audit the answer before they spend money.

The same pattern also protects the product. If a source is not ingested, changed, or authority-specific, the answer should say so plainly instead of quietly filling gaps.

Jurisdiction modules matter

Jersey and Ireland should not be blended into one generic planning model. Jersey has its own Island Plan, appeals route, register structure, and parish context. Ireland is plan-led through national law and city or county development plans, with local zoning and validation requirements doing much of the practical work.

A serious planning product needs separate modules, shared UX, and explicit source provenance for each country. That is the direction Planeer is taking.
