Jarred Sumner ported Bun from Zig to Rust last week.

960,000 lines of code, ported in six days, with 99.8% of the test suite still passing on the other side.

He didn't type most of it.

He wrote a spec, handed Claude the task, and let it run hundreds of agents in parallel, with two more agents assigned to argue against every file before it got committed.

That prompt pattern is what Anthropic shipped publicly today, packaged as Dynamic Workflows.

The technique itself has been doable for months, as long as you were willing to script the orchestration by hand.

As of today it's a toggle in the effort menu.

Before We Begin

It's Google's free AI marketing tool, built by Google Labs with DeepMind.

You give it your website and it reads the whole thing the way a creative director would, picking up your colours, fonts, tone and products.

Off the back of that, it does the work of a full marketing team.

If you don't have a website yet, you can build everything from a few images instead, and we'll cover both.

Step 1: It learns your brand

For the demo I used H&M, as they have a deep catalogue and a heavy site.

You paste the URL, hit continue, and it goes to work.

It runs through the site, pulling the colours, fonts and logo, learning the tone of voice, and writing you a tagline to match.

A couple of minutes later you land on a full brand profile it calls your Business DNA.

The tagline it wrote for H&M is more or less their real positioning.

Step 2: It builds the campaigns

Open the campaigns tab and it has already drafted three concepts off your brand.

Pick one and a few seconds later you have four finished poster creatives, built from real product images in the catalogue with the headlines and layouts already done.

Click any creative and a full editor opens up.

You can rewrite the headline, swap the font and colours, edit the description, and switch a call-to-action button on or off.

There's also a "fix layout" button that re-spaces everything so nothing comes out cramped, which removes the most tedious part of design work.

Two side tabs are worth knowing about.

The catalogue holds every product it scraped, each with a name and description it wrote itself.

The assets tab holds every image it pulled from your site, and deleting the off-brand ones there trains it to stop using them next time.

Step 3: The product photoshoot

You pick a product, choose a template from the gallery (it's split into fashion, beauty, home and consumables), and the standout option is model try-on, which drops your product onto a photorealistic AI model in a setting that fits your brand.

A minute later you get four variations, and the lighting and styling could pass for a real studio shoot.

From there you can save them or push them straight into a campaign.

Step 4: The brand book

Bringing on a freelancer or an agency usually means explaining your brand to them over and over.

Pomelli just writes the brand book for you.

You pick a cover and a few supporting images, wait about a minute, and it produces a proper guide covering your logo rules, typography, the colour palette with exact hex codes, and even the brand voice written out.

You can download the whole thing as a PDF, or publish it as a link that updates itself every time you make a change.

Step 5: The website

The website tab needs almost nothing. You click it, and it starts building.

What comes out is a full landing page pulled straight from your brand profile, with the hero section, product grid, gallery and copy all matched to the brand.

You can prompt it to rework any section, then publish to a live URL that holds up on mobile and desktop.

No website? build the brand from scratch

Everything up to here assumed you have a site to scrape.

The more useful path, and the one most walkthroughs skip, is starting from nothing.

So I made up a brand to test it: Gulaabi, a handcrafted Kundan and Minakari jewellery label out of Jaipur.

Instead of a URL I uploaded eight product photos, and the agent read each one and built the brand profile straight off the images.

I added a short description of the brand, its heritage, its colours and the kind of customer it sells to.

See the results for yourself:

A freelancer can run Pomelli on a prospect's site before the first call and walk into the pitch with the client's brand already built and a campaign already live.

That wins work before you've even quoted a price.

And the same tool then handles most of the actual delivery, so you take on more clients and bill for the outcome instead of the hours.

It cuts both ways, though.

Once the assets are free and instant, that is not what anyone is paying you for anymore.

The value moves to the judgment around it: knowing which of the four options is any good, what to cut, what the client won't say out loud, and being the one who answers for it when it ships.

"I can make you a logo" stops being a business the day your client can do the same thing for free.

Same catch on the small business side.

They could run Pomelli themselves for nothing today, and most won't, because they don't have the eye or the time, which is the exact gap a sharp freelancer sells into.

But that window is already closing.

So if you freelance, start using this now, while most clients still don't know it exists, and don't confuse the tool with the reason they hired you.
