AI Brand OS encompasses all your brand rules, allowing agents to apply them

AI Brand OS fits seamlessly into your existing agentic development and marketing workflows, ensuring every output follows your brand’s precise style.

Agentic development doesn’t have to mean boring UIs and same-y gradients

AI models are capable of producing interfaces that accurately match your brand. AI Brand OS helps your agent to ‘think’ like a designer in your team.

01 - brand design

optional

We bring you three concepts. You choose your favourite. We design the full new brand for your business. Includes a Figma design system with logos, colours, type systems and layout rules.

02 - codified design system

We take the brand design and codify it, so it’s ready to be used by both humans and AI agents.

03 - ai-centric instructions

Going past colours and typography, we provide dedicated instructions on motion rules, tone of voice, and how the brand should be implemented in different contexts. All ready to drop into Claude Code, Codex and Cursor.

Output using AI Brand OS Basic AI output

Once AI knows your brand, the drift stops, and the outputs actually ship.

Founders use Claude to draft landing copy, Cursor to build components, and ChatGPT to keep marketing assets moving.

Without a brand spec, every output drifts. Wrong tone, wrong colours, wrong typographic feel. Tokens wasted. Hours spent correcting it, or ditching it completely.

With our AI Brand OS, the brand is in context from the start. The drift stops. The output ships.

What our founders think

The design partner for AI-first founders

We previously had two designers in-house and we all agree that you were more productive than both of them put together in the quality of work that you produced. You were fantastic. Your price could definitely be higher and it wouldn't even be a question in my mind.

- Robert van den bergh, Founder & CEO of fluent

We interviewed 8 or 9 designers before deciding on Lightning UX and never looked back. We always get praise about our site and app design!

- sarah touzani, co-founder & ceo of waggle ai

Lightning UX understood my business and goals, and manifested that into an approach I could have only dreamed of had I done it alone.

- keyton weissenger, founder of whenivity

Michael helped us take a cobbled together idea of our rebrand and bring it to life, with a defined style guide, amazing new website in Webflow and we’re continuing with many other UX initiatives.

- philip storey, founder of enchant agency

Lightning UX took my idea for a cool, 80s themed B2B site for founders and delivered an amazing brand and website.

- matt hayes, founder of b2beach

Lightning UX has helped us overhaul our charity’s website, making it more usable, accessible and attractive to visitors. They have been flexible while paying close attention to detail to help us meet our objectives.

What is AI Brand OS?

AI Brand OS is Lightning UX's new package for helping founders build and ship agentically-developed products and sites that maintain their cohesive branding.

Often, AI outputs vary in their style. This can cause a problem when trying to build brand equity, create a consistent feeling and ensure a positive user experience.

When you purchase AI Brand OS, we'll help you turn your branding into a set of markdown files (along with a Figma design library) that AI can easily interpret and reproduce.

If you don't already have a brand, we can help you quickly create one. We'll develop three brief concepts going down different visual routes. You can then pick your favourite, and we'll develop out the branding, while also codifying it for AI.

How much does AI Brand OS cost?

If you're not looking for a brand redesign, the cost will be £999 (excluding VAT, if applicable).

If you would like a brand redesign as part of the package, the total cost is £2,499 (excluding VAT).

Which platforms support AI Brand OS?

AI Brand OS produces markdown and other file types which can be dropped into pretty much any AI or agentic coding platform.

We have seen great results in Claude (including Claude Code), ChatGPT (including Codex), Cursor and Lovable, but the same results would be expected for other AI platforms that allow you to supply context with your prompts.

How well does AI Brand OS work?

We believe AI Brand OS is one of the missing pieces in agentic development and AI-driven marketing.

Right now, AI is capable of producing great interfaces, code and imagery, but often lacks the context of your brand that it needs in order to consistently perform at the level you'd want for code and assets that actually ship.

Examples of how AI Brand OS influences AI output can be seen in the comparison slider section above. These examples were one-shotted with ChatGPT 5.5, and show significantly different levels of output.

We carefully recreate your brand aesthetic, feeling and rules in files which provide AI with that much needed context, so you can simply drop it in and forget about it.

We're constantly looking to improve AI Brand OS, so if you find a use-case that it could work better at, we'd love to speak to you.

What's the benefit of using AI Brand OS?

Put simply: time, money, effort and tokens.

Founders are often going back and forth with AI for hours trying to mould the output into something they can show others or ship.

With AI Brand OS, the back and forth significantly decreases, because AI has everything it needs to know about your brand before generating a line of code or image.

This means you can spend more time on the bigger picture, and less time and money wasting tokens on trying to align one feature with another.

How does AI Brand OS differ to uploading an image or PDF of our brand docs?

AI struggles to get precise information about your branding from images and PDFs, and often has to make best guesses.

AI Brand OS provides it with exact values, variables, bezier-curves and references so there's no guesswork. This means the outputs are always more aligned with your real brand, and not a version of the brand the AI has hallucinated.

Who is AI Brand OS ideal for?

AI Brand OS is most useful to founders, engineers and marketing teams who are adopting AI and agentic development and marketing workflows.

Do I need to be technical to understand AI Brand OS?

No.

Once we've codified your brand, we'll simply supply you with files that you can drop into chats or agent contexts. You don't need to review every line (unless you'd like to!) as we'll have manually written the rules for the AI based on your brand.

Does AI Brand OS benefit code generation?

Yes.

AI-generated code will reference your branding when building out new features and interfaces, and so there will be less re-work, along with less static values used, and more reference to re-usable variables.

Does AI Brand OS benefit marketers?

Yes.

AI Brand OS can help marketers generate landing pages, images and copy that is instantly better-aligned with your real brand.

Can I buy AI Brand OS for my team?

Yes.

When you buy AI Brand OS, there's no limit on who can access the files and context, so you can share it amongst your entire team of developers, marketers and agents at no extra cost.

Is this a subscription, or a one-off purchase?

This is a one-off purchase.

If you need a brand redesign, the cost is £2,499 (excluding VAT, if applicable). Otherwise, the cost is £999 (excluding VAT, if applicable).

What does the brand redesign consist of?

If you'd like a brand redesign as part of the package, it will consist of:

1. Us presenting you with three, single page brand concepts. All of these will vary in their aesthetics and vibes, to give you variety.
2. You'll pick your favourite and inform the direction.
3. We'll build out the concept into a full brand design system.

The brand design system includes:
- A set of logos
- A colour scheme
- A typography system
- Example brand imagery and graphics if applicable
- Examples of some common UI components

This design system will be provided in Figma and in the files optimised for AI agents.
