Bold Sport
Black canvas, heavy rounded type, neon-lit devices.

everything it
passes over.
Borealys turns the screens you already have into a store-ready set. The model writes the campaign — a renderer draws it, so your interface arrives exactly as you built it.

The method
The model decides.
The renderer draws.
One pass reads your actual screens and writes the campaign — the headline, which screen proves it, where to crop. That’s the whole of what the AI is trusted with.
Everything you download is drawn by a deterministic renderer from that decision. Which is why your interface arrives exactly as you built it, down to the pixel, instead of being repainted into something that only resembles your app.

Four kits
Not templates.
Design systems that hold.
Each kit is hand-authored — its own typography, palette, and composition rules. Your copy and screens flow into it, and the layout stays right whether a headline is two words or nine.
Fitness · Sport
Marker Pop
Blush blobs, ultra-condensed headlines, hand-drawn marks.
Editorial Warm
Cream and caramel, editorial type, testimonial cards.
Bold Grotesk
Swiss grotesque in gold and cream, keyword tags, callouts.
Make every headline shorter — they're wrapping to three lines.
Trimmed all five to the kit's two-line measure. Frame 3 lost its subtitle to fit — say the word and I'll put it back.

The editor
Ask for the change.
Say what you want in your own words and the set re-renders. No layer panels, no re-uploading, no starting again.
Every answer becomes a version you can return to — so trying something is never a decision you have to be sure about first.
Pricing
Priced per set,
not per seat.
Revisions don’t cost anything — changing a headline re‑renders the set, it doesn’t start a new one.

Questions
Before you start.
Do I need to be a designer?
No. You upload the screens you already have, pick a kit, and the set comes back composed — headlines, layout, colour, device treatment. If you can take a screenshot you can ship a set.
Will my app still look like my app?
Yes. Your interface is placed, never repainted. An image model would redraw your UI into something that merely resembles it; here the model only decides the campaign, and a deterministic renderer draws the result — so your screens arrive exactly as you built them.
What sizes do I get?
Exact dimensions for every App Store size, rendered to spec so uploads pass validation the first time. No resizing, no rebuilding a canvas per device.
Can I change something after it renders?
That's the editor. Ask for the change in plain words — shorter headlines, a warmer accent, swap frames two and three — and the set re-renders. Every change is a version you can return to.
Do revisions cost extra?
No. A revision re-renders the set you already have rather than generating a new one, so iterating is free. Credits are only spent when a new set is produced.
How long does a set take?
About a minute from upload to finished frames.
