The Ads You Didn't Approve: Amazon's Default-On AI Creative, Explained

You never filmed a video for that SKU.

There's one running on it anyway. Amazon built it stitched together from your product photos, set to motion, pushed live into your Sponsored Products placements. Nobody on your team briefed it, reviewed it, or signed off.

That's not a glitch. It's the direction the platform has been moving all year, and most sellers I talk to haven't clocked how far it's gone. Amazon has quietly slid into the creative chair. In some accounts it's making the video. In others it's picking which of your products a shopper sees. Sometimes both.

Convenient? Absolutely. Free, in a lot of cases. But "free" and "on by default" together mean something specific: you can be running machine-made creative you've never actually looked at.

Two quiet moves that put Amazon in the creative chair

The first is auto-assembled video for Sponsored Products. Amazon takes the image assets already on your listing and builds a short video ad out of them, no shoot required and no line item on the budget. Practitioners running large books of business have flagged it turning up switched on rather than waiting to be switched on. Prem Gupta, who mentors at Pare and has managed accounts north of $200M a year, was one of the voices calling attention to it this spring.

Whether it's on in your account is worth checking rather than assuming. Amazon has a track record here. When the platform bolted "off-Amazon" reach onto Sponsored Products, plenty of sellers only discovered it after their ACoS jumped, because the setting arrived on by default with almost no announcement. The Seller Forums lit up about it for weeks. Same playbook, new feature.

The second move is bigger. Back in late January, Amazon overhauled Sponsored Brands product collections into an AI-curated format. The custom headline and the lifestyle image you used to control? Gone. Ads now pull straight from your detail pages, and you're required to run between three and ten ASINs in a single unit.

There are two modes. In automatic, Amazon's AI decides which products from your eligible pool to show each shopper — reading their search query, their browsing, how your SKUs have converted before — then writes the ad title and builds the landing page for you. You hand over a brand name and a logo, and that's your contribution. In manual, you still pick the products yourself. Mansour Norouzi walked through both inside the console in a widely shared post; the short version is that automatic hands the wheel to the algorithm and manual keeps it in your hands.

One agency described the shift as pulling the "brand" out of Sponsored Brand ads. That's a fair read.

Why "free creative" is a real lever — and a real liability

Start with the upside, because it's genuine.

Video moves click-through rate. It always has. The wall was never demand for video — it was the cost and the wait. A proper product shoot can run anywhere from a few hundred dollars to several thousand per SKU, and weeks of calendar before anything ships. Auto-assembled video knocks that wall down, which is a real gift to a seller with a wide catalog and a thin creative budget. On the collections side, Amazon's own beta numbers claim automatic curation touched roughly three times as many unique search queries and drove about two and a half times more unique products purchased than hand-picked collections. Take the figures as Amazon's, not gospel — but the direction is believable.

Now the other edge of the same blade.

Default-on plus no review means a machine is choosing your product mix and cutting your visuals with no human gate in front of it. That's fine until it isn't. The auto-assembly grabs a frame that reads off-brand. Automatic curation pairs your hero product with a clearance item and a discontinued color in the same premium placement. A regulated claim ends up on screen in a context your compliance rules don't allow. None of that requires malice from the algorithm — just the absence of a person who knows better looking at it before it runs.

Who should actually care (and who shouldn't panic)

Not everyone needs to lose sleep over this.

If you're a smaller seller with a broad, low-sensitivity catalog, the free video is close to pure upside. Let it run. Watch what it does to CTR and conversion, and keep it if the numbers hold. You were never going to fund a shoot for every SKU anyway.

The sellers who should pay real attention are the brand-registered ones who've spent actual money building a consistent look. A stitched-together auto video can quietly undercut a visual identity you paid a studio to establish, and you won't see it happen unless you go looking.

And then there's the group at the top of the risk list: premium and regulated products. Supplements, anything medical-adjacent, baby, beauty with claims constraints, high-ticket goods where positioning is the whole game. For these, an unreviewed frame or an AI-chosen product pairing isn't a minor blemish. It's a compliance exposure and a brand-equity problem wearing the same coat.

The decision isn't blanket it's per account

Here's where I land after doing this across a lot of catalogs. Don't make one sweeping call. Make it account by account, sometimes SKU by SKU.

Opt in where the volume is high and the brand risk is low — that's where free machine creative earns its keep. Opt out, or drop to manual, on the premium and regulated lines where a wrong frame costs more than a video ever saves you.

The controls to do that already exist. Run Sponsored Brands collections in manual mode when the product mix has to be deliberate. Use product exclusions — Amazon lets you block up to a thousand ASINs — to keep clearance, low-margin, and off-season items out of the automatic rotation before they show up somewhere expensive. Check whether auto-assembled video is live on your Sponsored Products and decide campaign by campaign. And keep your own Sponsored Brands video running as the layer where you still control every second, since that's your controlled brand-building slot now.

Put "AI creative status" on your audit checklist

If you onboard accounts, or you're auditing your own, add one line: what has Amazon already turned on?

Check what auto-assembled video is running. Check whether collections are in automatic or manual. Check which ASINs are sitting in the automatic pool, and what's excluded. The old assumption was that nothing runs until you build it. That assumption is dead. The new default is that something is already running, and the audit is how you find out what — before a client asks why their supplement is sharing a frame with a bath mat.

FAQ

Is Amazon auto-generating my ad videos?
It may be. Amazon can assemble video for Sponsored Products from your existing image assets, and operators are reporting it active in accounts without an explicit opt-in. Confirm inside Campaign Manager rather than assuming it's off.

Can I turn Amazon's AI video off or take back control?
You can manage it at the campaign level and continue uploading your own Sponsored Products and Sponsored Brands video, which keeps the creative under your control. Check each campaign — behavior isn't uniform across accounts.

What changed with Sponsored Brands collections?
As of late January 2026, product collections became an AI-driven format with no custom headline or lifestyle image, a three-to-ten ASIN requirement, and dynamic product selection. Ads now build from your detail pages instead of uploaded creative.

Automatic or manual mode — which should I pick?
Automatic suits high-volume, low-risk catalogs where scale and personalization matter more than precise control. Manual suits premium products, tight margins, new launches, and anything where the exact product mix and positioning have to be deliberate.

Does the free auto-assembled video actually help?
Often, yes — video generally lifts click-through, and removing production cost lets you show it on SKUs you'd never have filmed. The catch is quality and brand fit, which is why it's worth watching rather than setting and forgetting.

How do I keep AI-generated ads on brand?
Use manual mode where the mix matters, apply ASIN exclusions to fence off products you don't want surfaced, keep your own controlled video running, and audit what's live on a schedule instead of trusting the defaults.

The seat's been taken — decide what you hand over

Amazon is going to keep moving into the creative chair. That's not a threat you can vote against; it's the shape of the platform now.

The sellers who come out ahead won't be the ones who reject all of it on principle, and they won't be the ones who let every default ride untouched. They'll be the ones who decide — per product, per account, with their eyes open — what they're comfortable handing to the machine and what stays in their hands.

That's the exact call I make across the catalog I run and the accounts I manage. If you want a second read on what Amazon has already switched on in your account, and a per-SKU policy for what to keep, hand off, or fence out, that's the kind of teardown I do before anything goes live.
