AI for planning applications means drafting the written parts of a submission (design and access statements, planning statements, heritage and validation checklists) from the scheme, the site and the relevant local policies, with every policy reference cited so the architect or planning consultant can check it before submission.
In England the policy stack is the National Planning Policy Framework, the local plan, supplementary planning documents and any neighbourhood plan, and each local planning authority publishes its own validation list. In Spain the equivalent is the municipal planning instruments (plan general, ordenanzas) and the licencia de obras process. The documents are long, the structure is familiar, and the failure that matters is a confident sentence citing a policy that does not say what the sentence claims.
So the system retrieves the actual policy text for the site’s authority and the current plan version, quotes it, and argues from it. Where it cannot find a policy for a point, it says so rather than filling the gap.
