Questions, answered.

No. OTTO provides planning guidance for England, drawn from published planning documents and quoted back to you with its sources. It does not create an adviser relationship. For decisions with legal consequences, consult a qualified professional.

Not on its word, and that is the point of OTTO. It only answers from the documents in its library, every claim carries a verbatim quoted passage with its document and paragraph reference, each answer is independently checked against the passages it cites, anything that check flags is re-examined further against the full Framework, an answer that still fails is shown to you flagged rather than hidden, and when the documents do not answer, it says so instead of guessing. You can verify any citation yourself against the public source.

Before any release, the system sits a 57-question audited exam over the full library, including trick questions and questions the documents genuinely cannot answer. Five gates, five pass bars, results published in full whether it passes or fails. The latest run scored 100% on citation accuracy and 100% on claims grounded in the sources.

The national layer that governs every district in England: the Town and Country Planning Act, the GPDO, the Use Classes Order, the NPPF and the rest of the planning statute book. On top of that sits each district's own layer: the adopted local plan, neighbourhood plans, emerging plans and evidence base. The library is checked nightly against the official registers.

OTTO says so, plainly, and shows you what the documents do say nearby. Declining to guess is scored as strictly as answering correctly in the published exam, because a confident wrong answer is the most expensive thing an AI can give you.

The whole industry: parish and town councils responding to consultations, planning consultants and agents who need citations they can put their name against, developers and land promoters appraising sites, and homeowners trying to get a straight answer. One engine, the same evidence for everyone.

Council plans start from £49 a month, priced to be approved in a single council meeting. Answer quality is identical on every plan, including the free tier when it arrives: paid plans buy workflow and volume, never better answers.
