01 / 05

Your real product.

We start from the product photos already on your store. Your cut, your fabric, your color.

02 / 05

A model your customer sees themselves in.

Cast from a portrait of your ideal buyer, not from a stock library.

03 / 05

The place they dream of.

A scene that fits your brand, lit like the rest of your ads.

04 / 05

A script and a voice.

A script written for this ad. Record it yourself, or pick one of 24 voices.

05 / 05

Subtitles that hold attention.

Several subtitle styles to pick from, each timed to every word.

That’s one ad. Made in minutes.

The old way

Your ads need new videos every week. A shoot gives you one batch a season.

Meta and TikTok reward fresh creatives. Here is what each new ad takes, side by side.

FAQ

Questions, answered.

Will it look like a cheap AI video?

Look at the ads above: they were all made with Castier. Every ad uses your real product photos, a model and a place picked for your brand, and you see a preview of each shot before the video is made.

Will the clothes look like mine?

Each ad is built from your real product photos, front and back. If a detail is off on one shot, you describe the change and only that shot is redone.

Do I need a shoot, product videos or a model?

No. The product photos on your store are enough. We suggest the model and the place, or you upload your own.

I’m not a video editor. Is it hard to use?

No. You pick, you check, you describe changes in plain words. The editor works like a simple timeline: cut, reorder, add your voice, music and subtitles.

What if I don’t like the result?

Change any shot by describing what you want, or make 2 variants with a new hook or a new script.

Can I use the ads on Meta and TikTok?

Yes. Every ad comes out in 9:16 with sound, ready for Reels, Stories, TikTok and YouTube Shorts.

Is the first ad really free?

Yes. Paste your store and get your first ad without a card.

Can my team work on it with me?

Yes. Invite your team by email: they work on the same brand, the same ads and the same library.

Which stores work with Castier?

Castier reads Shopify stores. Paste your store address and we do the rest.
