One person needs no account, no card, no telemetry.
A shared vault costs a seat for each person in it.
Every price is on this page, and what is on sale today.
£0, forever.
The whole app on your own Mac: the vault, answers with their sources, the council, and a seal on what you make. No account, no card, no telemetry. It is not a trial and it does not end. One person means you, on every Mac you own.
After ninety days of use the app asks once whether you want to pay for it: £8, £25, any amount from £3, or nothing. Say no and it never asks again, and nothing changes either way.
Not out yet Join the waiting list and you will hold the first public build. Two things in this row are not shipped yet: one vault on two of your Macs at once, which comes with the shared vault, and the ninety-day ask, which comes with the checkout.
£240 a seat, a year.
One vault opened by more than one person: a firm, a practice, a household, two people who work together. It is kept as plain files on hardware you own. A seat is one person who opens that vault with their own key. Your own Macs are not seats.
The least you can buy is two seats, £480 a year, on one invoice, with no setup charge. The price is the same whoever buys. Two people who each keep their own vault and pass sealed files between them pay nothing.
Not on sale yet It goes on sale when two things ship: the import of PDF, Word, mail and meeting transcripts, and the vault shared by several people.
Free, £8, £25, or any amount from £3.
The papers Third ARK writes and publishes, each one sealed so a stranger can check it without us. Read a copy for nothing, or pay what it was worth to you. Each payment buys a licensed copy with a numbered receipt.
Not on sale yet The Shadow AI white paper is free to read now, and paid copies go on sale when the checkout is built.
Prices are in pounds sterling. Third ARK Limited is not registered for VAT, so no VAT is added.
