Use Design Systems feature in Claude Make any documents and content in Claude match my colours and fonts on the first run usually. It’s how I get documents and slide decks back in my brand and my tone of voice, instead of fixing them after. You build it once. After that you tag it in the chat and Claude follows it. To build yours, open Claude Design, start a new design system and pick “create using Claude”. Make sure your AI Brain is selected in that chat. Then give it your website and screenshots of a few past decks or proposals, plus your brand files if you have them. Let Claude work out the spacing, shadows and text sizes - even logo! You don’t need to pick those yourself.
