How to attract initial users for a new AI reviews app?

[StanPlatoria]

Hello,

We have just launched a reviews app that works with AI - Platoria. We solve the problem that most stores don't have enough reviews on their products, so our AI review summaries provide them with the essence of hundreds of reviews per product.

How can we find our first users? The Shopify ads seem far too expensive because the CPC is around $5. 

Thanks!
