The live wall

Several directions, running side by side

Not one result you keep regenerating. Every direction is real HTML, and you compare them on one wall.

  • Each direction is real HTML, not a picture of one
  • Genuinely different directions from one brief
  • Your pick is the only label

How it works

Brief, directions, wall, pick, verify

One brief fans out. You compare and pick. What ships is checked.

  1. Brief
    Say what you want built, and for which target.
  2. Directions
    One brief fans out into several genuinely different directions, each one real HTML.
  3. Wall
    Compare them side by side on one live wall.
  4. Pick
    You pick. A model never picks for you.
  5. Verify
    What ships is checked against the target's gates, which say what they could not check.
We say what we cannot verify

Checked against the gates. Where a gate cannot measure, it says so.

Every gate returns one of three outcomes: pass, fail or could not measure. A run where nothing failed but something could not be measured is incomplete. Outlook cannot be rendered locally, so an email's best verdict is incomplete, and Nucleus says so.

  • A gate that cannot measure is never counted as a pass
  • Every reason is written down, next to the gate
  • The same gates run on every direction you pick

Verify: email

every gate at its best
Incomplete
  • SizePass
  • No script or externalPass
  • Inline stylesPass
  • Table layoutPass
  • ImagesPass
  • WidthPass
  • PreheaderPass
  • Dark modePass
  • Compliance footerPass
  • Tokens-only colorsPass
  • Plain textPass
  • Chromium renderPass
  • Client renderCould not measure

    Outlook (Word engine), Gmail and Apple Mail rendering cannot be reproduced locally. Check the email in real clients, or a rendering service, before it is sent.

Not a recorded run: the email gates in the order Nucleus runs them. A run is a pass only when every gate passes, and Client render can only answer could not measure, so this is the best an email can get: incomplete.

For freelancers

The approver signs off one look, and it is recorded

For builders shipping alone, and for freelancers whose client has the last word. Invite your client with a single-use token. They comment, vote and approve a look.

  • The approval pins the exact HTML by its sha256
  • It records which account approved, on what basis, and when
  • Never edited: a new look is a new round and a new approval

What Nucleus does not do

Claims we can keep, and nothing else.

  • Does not train on your data
  • Every preview runs apart from the app
  • No fetches or form posts from a preview
  • A model never picks for you

Pay once to create it, with the first month included. Then one monthly price keeps it current. Cancel any time. Prices are in US dollars.

Frequently asked questions

What is Nucleus?
Our first product: the design review app with an AI art director and production team built in. Start with a brief and get finished email, web templates and WordPress themes.
Can I use Nucleus today?
Nucleus is in early access, and this page says exactly where it stands.
What can it make?
Email, web templates and WordPress themes today, with more on the way. We will say here when something new is ready to use.
How does the pricing work?
Pay once to create it, with the first month included. Then one monthly price keeps it current. Cancel any time.
What does first month included mean?
The creation fee covers making the work and its first month of being kept current. The monthly price starts after that month, and you can cancel any time.
What does the monthly price keep?
Unlimited maintenance changes inside the locked design. Brand kit updates, re-checked for WCAG 2.2. A new look is a Design refresh, $795, not a maintenance change.
What does in development mean?
The product has its price and is not built yet, so it cannot be bought. A product is built only when every piece it is made of is built. Today the Design to Build is, and the rest are in development.
Do the people who review my work pay?
No. Reviewers and approvers join free and never see a price.
What if I already have a brand kit, a SOW or a PRD?
Import it free and skip that piece.
Does Nucleus train on my data?
No. Nucleus does not train on your data.
