Google has added a way to define your brand style inside Gemini. You upload your website, brand kit, fonts or colour palette, and Gemini keeps that style in mind when it makes visuals. That means you do not have to explain your brand colours and fonts in every new chat.
This post gives you the exact prompt from the Instagram carousel, shows how to set up your brand style first, and lists what to check before you post anything.
What you need
A Gemini account. Google says its new business tools are beginning to roll out globally for all Gemini app users, so you may not see them on day one.
Your brand material. Your website link, brand kit, fonts or colour palette. Use whatever you already have.
The basics of your product. Its name, what it is, who it is for, and any real offer you want shown. Gemini should work from your facts, not guess them.
Step by step
Step 1: Add your brand style
Open Gemini and look for the new business page or the option to define your brand style. Google says the rollout starts over the coming days, so the exact place can differ by account.
Upload your website, brand kit, fonts or colour palette. Google says Gemini retains this visual style so it can create cohesive, on-brand assets.
Step 2: Paste the prompt
Copy this prompt into Gemini and replace [product] with your product:
Using my uploaded brand kit, create a 5-slide Instagram launch campaign for [product]. Keep the typography, colours and visual identity consistent. Make each slide communicate one clear idea. Avoid invented claims and prices.Step 3: Give it real product details
A product name plus a short description gives Gemini more to work from than a name alone. If you want a real price or offer to appear, add it yourself:
Use only these product details: name [name], price [price], offer [offer]. Do not add anything else.Step 4: Fix one slide at a time
Review what Gemini gives you slide by slide. If one slide is off, ask for that slide only:
Rewrite slide 3 so it communicates one clear idea: [your idea]. Keep everything else the same.Why the prompt is written this way
"Using my uploaded brand kit" points Gemini to the brand material you added.
"5-slide Instagram launch campaign" sets the format and the length.
"Keep the typography, colours and visual identity consistent" asks for the same look on every slide.
"Make each slide communicate one clear idea" keeps slides from getting crowded.
"Avoid invented claims and prices" asks Gemini not to make up details. It is a request, not a guarantee, so check the output yourself.
Check before you post
AI-generated visuals still need a human review. Go through this list first:
Text. Spelling, claims and numbers.
Product details. Names, variants and prices.
Logos. The correct version, with clear space around it.
Brand accuracy. Colours, typography and tone.
Good to know
Rollout. Google says the business page, new skills and connected apps are beginning to roll out "in the coming days" globally for all Gemini app users. If you cannot see brand style yet, it has not reached your account.
Image model. Google pairs brand style with Nano Banana 2.1, which it calls its latest image generation model.
Price and limits. Google's announcement does not name a paid plan or list limits for brand style, and it does not say how many brand styles you can save. If you manage several brands, check inside Gemini and check what your own plan includes.
Privacy. A brand kit can include unreleased products or client material. Share only what you are comfortable giving an AI tool.
Accuracy. Google marks generative AI as experimental, so expect to edit the results.
Labels and disclosure. Check Instagram's current rules for labelling AI-generated content, and use the paid partnership label if the post is sponsored.
Larger companies. Google points businesses that need admin controls and data governance to a separate offering called "Gemini for your business".
