For small business owners

ChatGPT and Claude, in your brand.

Paste your website. We turn it into one file that teaches ChatGPT and Claude your colors, fonts and voice.

Free in beta. No account, no card.

how it works · 3 steps

Three steps. No design or coding.

  1. 01

    Paste your website

    We read your site and pull out what makes it yours: colors, fonts, logo and voice.

  2. 02

    Check it

    See everything on one board and fix what is off. Something missing? One button fills it in for your kind of business.

  3. 03

    Give it to your AI

    Download the file and add it to ChatGPT, Claude or the tool you build with. Every draft then follows your brand.

What is the brand file?

Plain text with simple headings and lists, saved as a .md file. ChatGPT, Claude and other AI tools read it easily and follow it. You never write it by hand.

07:00 · the morning post

Ask for a post.Get your post.

The sourdough is out and Instagram needs a post. ChatGPT gives her the same blue square it gives every bakery.

She adds her brand file once. Same request, and the post comes back as Ferment.

16:00 · the new offer

Write an offer.Sound like you.

A bread subscription could carry the shop through winter.

The page comes back in her voice, with her price and her colors.

19:00 · closing time

Two jobs, one chat.One brand.

A post and an offer, both of them Ferment.

One file that tells every AI who you are.

faq

Short answers.

Is it free?

Yes, while brandmarkdown is in beta: the full pack, no account, no card. Paid options are planned, and anyone on the list gets one message when they start.

What exactly do I get?

A folder of files. The main one is your brand file, DESIGN.md. The rest are the same rules shaped for each tool, including a short version.

Do I need to know how to code?

No. You paste a website address, check the result and download. Adding the brand file to ChatGPT or Claude is the most technical step.

How do I use it with ChatGPT or Claude?

Add the brand file to a ChatGPT or Claude project. In ChatGPT, also paste the short version into the project instructions. Our guides show it click by click.

I build my site with AI. What then?

Tools that work in your project folder, such as Claude Code or Cursor, read the pack there on their own. In Lovable, v0 or Bolt, paste BRAND-SHORT.md into the project Knowledge or instructions.

Where is my brand stored?

In your browser, on your device. You can download every file.

Do I need to connect anything?

No. It works with the ChatGPT or Claude account you already have.

I already have a brand book.

Drop the PDF or your own .md files at the start. What your book does not cover is marked, so you can fill it in.

See your brand in a minute.
