GenieOS for agencies
Every client, in their own brand, from one place.
Give each client a workspace with its own brand book, strategy and sign-off. Genie makes the work in their look and voice, your team refines it, and clients approve it without the email chains.

Client sign-off
Present it once. Get the yes in one place.
Every piece of a campaign sits together for review: the email, the page and the posts. Clients see the whole idea in their brand, ask for changes in plain words, and approve it where your team can see.
- Changes land on the piece, not in an email thread
- A clear record of who approved what, and when
- Approved work goes straight out on schedule
Built for client work
Grow the client list, not the overtime.




A workspace per client
Each client keeps its own brand book, strategy, assets and history, so nothing from one account leaks into another.

BillboardMore output per head
Genie drafts the campaign in the client's look and voice. Your strategists and designers spend their time on the ideas, not the resizing.

Your process, not ours
Set sign-off rules per client. Work moves from draft to review to approved, and everyone can see who said yes.
How it works
From brief to launch-ready in one sitting.
- 01
Genie learns your brand
Paste your website. Genie reads your logo, colours, fonts, tone of voice and the kind of photography you use, and keeps it as your brand book.
- 02
You write the brief
One line is enough: who it's for and what you want them to do. Genie plans the campaign and makes every piece to fit.
- 03
Your team reviews and approves
Edit anything in plain words or by hand. Nothing goes out until the right person has approved it.
- 04
Every campaign teaches the next
Results flow back in. Genie learns what works for your audience and the next brief starts smarter.

Questions, Answered.
What can I create from one brief?
A coordinated campaign with emails, social posts and landing pages, or a single piece when that is all you need. GenieOS uses your brand and campaign brief across the assets so they work together.
How does GenieOS learn my brand?
Start with your website. GenieOS builds a foundation from your colours, typography, imagery and voice. Review and refine that foundation, then use it across your campaigns.
Can I edit the work before it goes live?
Yes. Ask Genie for changes in chat or use the editors directly. Review the campaign, share it for team approval and choose when to launch. You control the work and its sign-off.
Do I need a developer to get started?
You can start with your website and a plain-language brief. Connect sending providers and social accounts when you are ready to publish. Connecting business data is a later step for measuring results against your own goals.
Can I sign up now, and what does Spark cost?
Yes. Create a Spark account straight away with your email, Google or GitHub. No invitation or card is required to get started. Spark is pay-as-you-go: every feature is available, and paid actions use credits. See the pricing page for credit costs and subscription options.
