About CreaSift

CreaSift is an ad creative intelligence tool for e-commerce advertisers. It studies publicly available advertising — Meta's Ad Library and TikTok's Commercial Content Library and Creative Center — to help brands see which creatives are running in their category, understand the structure behind them, and produce their own compliant ads faster.

We sell decision efficiency, not volume: fewer wasted creative tests, faster time from reference to a finished ad.

Weiwei founded CreaSift after years of running direct-to-consumer e-commerce stores in custom apparel and personalized gifts, where the hardest recurring problem was not producing ads but knowing which creative direction was worth testing. CreaSift turns that research process into a product.

How we use public ad data

We analyse ads that platforms disclose publicly for transparency purposes. Our analysis is aggregated and pattern-level (hooks, pacing, offers, calls to action); we do not resell or redistribute raw ad data, and we follow each platform's API terms.
