Prooftiles

Prooftiles positions itself as a step up from the typical social proof widget. Where tools like Fomo and Notify mainly let you display recent activity, Prooftiles pushes into optimization territory with its AI Personalization Engine, which claims to live-tune your notification messages based on what's converting. That's genuinely useful if you're running A/B tests and want the system to learn which copy, timing, and placement work best for different segments. The behavioral targeting—by page, device, and referral source—adds another layer that most competitors lack. You can show different notifications to mobile visitors versus desktop, or tailor messaging based on where the visitor came from. This is the kind of granularity that growth teams appreciate. The Shopify Checkout integration is a standout. Most social proof tools stop at the cart page or below the fold. Getting your proof notifications onto the checkout page itself can meaningfully lift conversion at the final step, and that's a differentiator worth calling out. On the downside, the pricing model is restrictive for smaller sites. With no free tier (only a 14-day trial) and the Starter plan capped at 2,000 visitors per month, a low-traffic hobby blog or a tiny store will likely find the cost hard to justify. The API documentation is described as sparse, which will frustrate developers who want to build custom integrations beyond the native ones. For whom does it fit? If you're an e-commerce store or SaaS company with decent traffic and a mandate to improve conversion rates through testing, Prooftiles gives you the tools to do that systematically. If you're a small site just starting out, you might be better served by a free or cheaper alternative until you have the volume to make optimization worthwhile.
