PAI Terms of Service

Version: 0.2. Effective: 6 July 2026.

These terms are a contract between you and Techzoom Ltd, a company registered in England and Wales (company number 15539411), registered office 71-75 Shelton Street, Covent Garden, London WC2H 9JQ ("we", "us"). They govern your use of PAI, our service for searching and analysing planning appeal cases.

By creating an account or using PAI you accept these terms. If you use PAI on behalf of a firm or company, you confirm you have authority to accept them for that organisation, and "you" then means that organisation.

1. What PAI is

PAI is an AI planning assistant for property and planning professionals. It helps you search planning appeal decisions and related documents, analyse them, and use what you find in your own work. PAI supports your professional judgement rather than replacing it: it does not give legal, planning or other professional advice, and its outputs are not a substitute for advice from a qualified professional.

2. Plans, trials and beta features

PAI is offered on the plans described on our pricing page, which may include free trials. For trials, we will tell you the length and what happens when the trial ends; we may limit, extend or withdraw trials at our discretion. When a trial or paid plan ends, your account and content remain in place (though access may be limited) until you close your account or ask us to delete your data. Parts of the service may be labelled beta or preview: those features may change, break or be withdrawn without notice, and we make no commitments about them.

If you send us feedback or suggestions, we may use them to improve PAI without owing you anything.

3. Your account

Keep your account details accurate and your login secure. You are responsible for activity under your account. Accounts are for a single named user; do not share logins. PAI is provided for business use in the course of your profession, not for consumers.

4. Acceptable use

You must not:

  • use PAI for anything unlawful;
  • upload content you have no right to upload;
  • probe, overload or interfere with the service, or attempt to access other users' data;
  • scrape, bulk-download or resell the service or its data;
  • reverse engineer the service, except where the law allows it;
  • use PAI or its outputs to build a competing product.

We may suspend accounts that break these rules (see section 13).

5. Your content

You (or your firm) keep ownership of everything you upload and of the queries and conversations you create. You grant us the licence we need to host, process and display that content in order to run PAI, and to improve it as described in our Privacy Notice (which also explains how to opt out of that).

You are responsible for what you upload. In particular, you confirm you have the right to upload it, and, where it contains personal data, a lawful basis for us to process it on your behalf.

We may remove content that we reasonably believe breaks these terms or the law.

6. AI outputs

The assistant's answers are generated by AI. They can be wrong, incomplete or out of date, and they can misread documents. They are not advice. Do not rely on them without checking the underlying documents yourself. You remain responsible for your own professional judgement and for anything you produce for your clients.

7. Case data and our rights

The appeal decisions and documents PAI searches are public records published by the Planning Inspectorate and local planning authorities; we do not claim ownership of them. We do own the PAI software, our databases and compilations, and everything else that makes up the service. Nothing in these terms transfers any of that to you.

8. Privacy and data protection

Our Privacy Notice explains what personal data we collect about you and how we use it, including our AI providers and sub-processors. Where you upload personal data about your clients or other people, we process it on your behalf under our Data Processing Agreement, which forms part of these terms.

9. Fees and payment

Current pricing is shown in the app when you choose or change a plan, and at checkout. Unless we agree otherwise in writing:

  • plans are billed monthly in advance through our payment provider, Stripe, and renew automatically each month unless cancelled before renewal;
  • each plan includes a monthly usage allowance that refreshes at the start of each billing month; unused allowance does not carry over;
  • top-up credit packs are one-off purchases and do not expire while your account remains open;
  • allowances and credits have no cash value and lapse when your account closes;
  • plan upgrades and restarts take effect immediately and are charged at the full new price, without proration or credit for unused time on the old plan; downgrades take effect at your next renewal;
  • prices exclude VAT, which is added where applicable;
  • if a payment fails or is overdue, we may suspend access after telling you and giving you a reasonable chance to pay;
  • we may change prices with at least 30 days' notice, taking effect from your next billing period;
  • fees are non-refundable, and no refunds or credits are given for part-used billing periods, except where these terms say otherwise (section 13) or the law requires.

Nothing is charged for free trials unless and until you move onto a paid plan.

10. Warranties and disclaimers

PAI is provided "as is" and "as available". To the fullest extent the law allows, we exclude all implied warranties and conditions, including fitness for a particular purpose. We do not warrant that the service, the case data or the AI outputs are accurate, complete or error-free, or that the service will be uninterrupted or secure.

11. Liability

Nothing in these terms excludes or limits our liability for death or personal injury caused by our negligence, for fraud or fraudulent misrepresentation, or for anything else that cannot be excluded under the law of England and Wales.

Subject to that:

  • we are not liable for indirect or consequential loss, loss of profit, loss of business, loss of data, or losses arising from reliance on the service or its outputs; and
  • our total liability to you in any 12-month period is capped at the greater of £100 and the fees you paid us in the 12 months before the event giving rise to the claim.

You accept that this allocation of risk reflects the price of the service, including that parts of it may be provided free of charge or on trial.

12. Indemnity

If a third party brings a claim against us because of content you uploaded or your breach of these terms, you will cover our reasonable losses and costs arising from that claim.

13. Suspension and ending the agreement

You can cancel your plan at any time; cancellation takes effect as described in section 9. Cancelling a plan does not close your account: your account and content remain available, on a free or limited basis, until you close the account or ask us to delete your data. When your account is closed, we will give you a reasonable opportunity to export your data first, then delete it as described in the Privacy Notice.

We may suspend or close your account if you materially breach these terms, if fees are overdue after notice, if the law requires us to, or if we withdraw the service (in that case, with reasonable notice and a pro-rata refund of any prepaid fees for the unused period). Sections 5, 7 and 10 to 12, and any other terms that by their nature should continue, survive the end of this agreement.

14. Changes to these terms

We may update these terms. For material changes we will give you at least 30 days' notice by email or in the app. If you keep using PAI after a change takes effect, the updated terms apply. If you do not agree with a change, you may cancel and close your account before it takes effect.

15. General

These terms, the Privacy Notice and (where it applies) the DPA are the whole agreement between us about PAI. If any part of these terms proves unenforceable, the rest still stands. If we do not enforce a term straight away, we can still enforce it later. You may not transfer your rights under these terms without our consent; we may transfer ours to a successor business. No one other than you and us has rights under these terms.

16. Law and disputes

These terms are governed by the law of England and Wales, and the courts of England and Wales have exclusive jurisdiction.
