- 1
Free starts from a design you upload. Its review flow, its invite, its sign-off and its gates all work on that upload, and uploading a design is not built yet. Back to the table
- 2
An approval records which account approved, on what basis and when, and pins the exact HTML of the direction it approves by its sha256. It is never edited: a new look is a new round and a new approval. What a sign-off on an upload will record is not decided yet. Back to the table

As planned, Builder's allowance is monthly and Studio's is higher. Neither is built yet: today the same limit applies to every plan, and no amount is decided. Whatever the amount, when an allowance is used up the call is not made, and Nucleus never switches to a cheaper model to keep going. Back to the table

Outlook cannot be rendered locally, so an email's best verdict is incomplete. Nucleus says so rather than calling it a pass. Back to the table

The zip is built for both. WordPress.com takes an uploaded theme only on its Business plan or above, and installing one there has not been checked. Back to the table
- 6
A review for a client is built from that client's own brand kit, so each client keeps its own brand. Back to the table
- 7
Today each client has one approver on record at a time: the signatory you record, or a designee your client names instead. Several approvers per project is planned. Back to the table

What each plan includes may change before launch. Paid plans will be billed monthly.
The sign-off
Every sign-off is a record, and it is never edited
Invite your client with a single-use token. They comment, vote and approve a look. The approval is stored as it happened, and a new look means a new round and a new approval.
- An approval of a direction pins its exact HTML by its sha256
- It records which account approved, on what basis, and when
- Approved by your client's signatory, or by someone your client designates

append-only, one per direction per round

- This one. Keep the type as it is.
A used-up allowance
When the allowance runs out, nothing cheaper runs in its place
Builder and Studio will generate directions within an allowance, and no amount is decided yet. When it is used up, the call is not made, and Nucleus never switches to a cheaper model to keep going, so a result is never quietly worse.
- The generation stops, and the job says why
- The answer has no field that could name another model
- A generation that renders nothing is not counted against the allowance

Questions
Straight answers about the plans
What does Free include?
Free is planned as the approval half of Nucleus: upload a design you already have, review it with one approver you invite, get a recorded sign-off, and run the gates that apply to the upload. None of it is built yet, because it all starts from an upload. Whether Free carries any model allowance is not decided yet.
Why are there no prices yet?
Because a price set before we know what a review costs to run would be a guess, not a number. Prices at launch. Paid plans will be billed monthly.
Does Nucleus train on my data?
No, on any plan. Nucleus does not train on your data.
What happens when my allowance is used up?
The call is not made, and the generation stops with the reason. Nucleus never switches to a cheaper model to keep going, so a result is never quietly worse.
How big is each allowance?
Not decided yet. Each will be sized from what a review actually costs to run, which has not been measured yet.
How does the table decide what each plan includes?
It reads each plan's own list. A plan is marked for what its list names, and for what an item on that list cannot work without: Studio's client approvers need the review flow, the invite and the sign-off, and its allowance is for generating directions. A dash is used only where a plan's list rules a thing out, the last group holds on every plan, and every other cell says not decided yet.
Is it open yet?
Not yet. Join the waitlist to hear when Nucleus opens.
