Shipping a branded AI app shouldn't be a six-figure project

For most organizations, putting a branded assistant in customers' hands means either a long engineering build or renting someone else's stack. Both come at a cost you keep paying.

Four codebases, one budget

A custom app means hiring engineers to build and maintain separate web, iOS, Android, and desktop codebases — a six-figure undertaking before a single customer logs in.

Renting your own experience

White-label chatbot platforms charge premium monthly fees to host your assistant on their stack — and your customers' data flows through it on the vendor's terms.

A second login, a lost context

Bolt-on apps drop users into a blank session: separate accounts, a second sign-in, and none of the memory they had a moment ago.

Design once. Ship everywhere your customers are.

One design → many surfaces

Mobile
Desktop
Browser

The same branded assistant, generated for phone, desktop, and browser.

One workflow

Every surface from a single canvas

Colors, logo, fonts, and voice are applied across mobile, desktop, and browser at once. Instead of maintaining four divergent codebases, you maintain one design and regenerate when it changes.

  • Native iOS + Android, plus desktop and browser surfaces
  • PWA and offline mode, with deep-linking and push notifications
  • App-store-ready bundles, with code-signing handled for you

Single sign-on handoff

Acme Assistant

Sign in with bRRAIn

Resumed your memory session

Welcome back — right where you left off. No second login.

One tap signs the user in and drops them straight back into their bRRAIn memory.

No second login

Users land right back in their memory

Single sign-on handoff carries an already-authenticated user straight into their exact bRRAIn memory session — no second account, no second sign-in, no lost context the moment they open the app.

  • Authenticated users resume their persistent session instantly
  • Conversations stay governed by your vault's permissions and audit
  • One identity across every surface you ship

Where the AI runs

Branded surfaces

Mobile · Desktop · Browser

Your bRRAIn

Your endpoints · your LLM Registry · your vault

Each surface is a thin, branded client over infrastructure you own.

Sovereign by design

Your stack powers the experience — not a vendor's

Every binary the Builder ships is a thin, branded client over your bRRAIn. The surfaces call your endpoints and your models through the LLM Registry, so the branded experience your customers see runs entirely on infrastructure you own and govern.

  • Never a third-party proxy sitting in the middle
  • Customer data stays inside your sovereign boundary
  • One brand kit applied consistently across every surface

From brand kit to app store in a workflow

Three steps replace a quarter-long engineering project.

Apply your brand kit

Drop in your colors, logo, fonts, and voice. Watch the branded assistant render live as you go.

Pick your surfaces

Toggle mobile, desktop, and browser. The same design carries to every surface you choose.

Generate app-store-ready bundles

Get signed, publishable bundles auto-wired to your bRRAIn, ready to ship to your customers.

What you'll use it for

Launch a customer-facing AI app

Put a branded assistant in your customers' hands — on the App Store, Google Play, desktop, and web — without standing up an app-development team.

White-label for partners

Give each partner a fully-branded surface over their own bRRAIn, so the AI carries their identity while running on your platform.

Internal branded assistant

Ship a company-branded memory assistant to employees across every device, with SSO so it just works the moment they open it.

One design, every surface

Maintain a single brand and a single workflow instead of four divergent codebases for web, iOS, Android, and desktop.

Field & offline use

PWA and offline modes plus deep-linking and push keep the experience working for mobile and field teams with intermittent connectivity.

Go to market in days

Move from brand kit to app-store-ready bundle in a workflow, not a quarter-long engineering project.

How it compares

Under 25% of the cost

Custom development runs into six figures and white-label chat platforms charge premium monthly fees to host your experience on their stack. The Branded AI UI Builder generates every surface from one workflow on infrastructure you own — for less than a quarter of the comparable build-and-host cost.

“We shipped a fully branded assistant to the App Store, Google Play, and desktop in four days — a launch we'd scoped at a full quarter with a contract dev team. And our users sign in once and pick up exactly where they left off.”

Questions, answered

Who hosts the AI, and where does my data go?

You do. Every surface the Builder ships is a thin, branded client over your bRRAIn — it calls your endpoints and your models through the LLM Registry, never a third-party proxy. Your customers' conversations and data stay inside your sovereign boundary.

Do I need developers to use it?

No. The Builder is a no-code studio: apply a brand kit, pick your surfaces, and generate. There's no separate codebase to write or maintain — when your brand changes, you regenerate from one source of truth.

Can I really publish to the App Store and Google Play?

Yes. The Builder produces app-store-ready bundles for native iOS and Android, plus desktop and browser surfaces, with code-signing handled for you so you can submit and ship.

What is the login experience for my users?

Single sign-on handoff. An already-authenticated user opening your branded app resumes their exact bRRAIn memory session — no second account, no second login, no lost context.

How does “under 25% of the cost” hold up?

Custom development runs into six figures across platforms, and white-label chat platforms charge premium monthly fees to host your experience. The Builder generates every surface from one workflow on infrastructure you already own — for less than a quarter of the comparable build-and-host cost. Your exact savings depend on scale and usage.
