Regulatory AI

Priced by the people asking, not the fleet flying.

Regulatory AI is licensed per seat — one for each person putting questions to Chuck. What changes between tiers is how much they can ask, and how much of your own documentation Chuck reads alongside the rules.

Per seat · from 3 seats · set up by our team

Looking for SMS Platform pricing? That is priced per plan, on its own page.

Seat tiers

Five tiers, one axis: how much asking a seat does.

Included usage is shown as a multiple of Starter rather than a number of questions, because a question you ask once is not the same size as a question you ask of a manual. The document library is a plain count, because you can go and count yours.

Launch offer

Double included usage for your first three months.

Regulation libraries

One is included on every listed tier, from Starter to Scale. Add the others at £167 per library / month, billed annually — or £200 billed monthly, two months free on annual. The price is the same whichever of those tiers you are on. On Enterprise, the libraries you need are part of the quote.

  • FAA
  • EASA
  • UK
  • 2-REG

Which tier fits?

Four questions, and it will show you the price.

It takes the higher of two floors — what your documents need and what your work needs — applies the bulk discount your seat count earns, and names the answer that set the tier. Disagree with it and say so when you get in touch.

One per person asking. Minimum 3.

One is included; each extra is charged.

Company documents

Your own manuals and procedures, searched alongside the regulations.

An estimate to start the conversation, not a quote. We would rather move you down a tier than watch you overpay.

Enterprise

Past thirty seats it stops being a table.

At 30 seats and above, and for groups running several entities, we price by volume rather than by band — and the constraints usually worth talking about are not the seat count anyway.

  • Regulation libraries scoped to your operation
  • Unlimited company documents
  • EU data residency
  • Single sign-on (SSO)
  • Volume pricing
  • Dedicated support

Billing

The rules attached to the numbers.

Usage beyond what's included
Additional usage is charged — and you can set a usage cap, so you are never billed beyond it.
Annual and monthly
Prices lead with annual — twelve months for the price of ten, so two months are free. Monthly billing is available on every tier at the monthly rate shown beside it, and both figures include any bulk discount your seat count earns.
Set up by our team
Seats are sold and provisioned by us — there is no self-serve checkout on this page. We agree the tier, the libraries and the seat count with you, then configure the tenant and hand over.

This is not the SMS Platform price list: the platform is licensed per operator, by fleet and headcount. Regulatory AI is per seat. Neither includes the other, and you can buy either on its own.

Bring the questions your team looks up most often.

We will run them in front of you, against the frameworks you actually operate under, and tell you which tier that lands in — including when it is the cheaper one.
