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.
