Grapevine Post Purchase Survey vs PlusSales ‑ AI A/B Testingfor Shopify (2026)
Grapevine Post Purchase Survey and PlusSales ‑ AI A/B Testing both aim to improve Shopify store performance through analytics, but their approaches differ significantly. Grapevine focuses on collecting customer feedback via various survey types (post-purchase, NPS, etc.) to understand customer satisfaction and identify areas for improvement in CX and marketing. Its strength lies in its unlimited survey responses and integrations with popular marketing and analytics platforms like Klaviyo and GA4, making it suitable for merchants aiming to deeply understand customer sentiment and build detailed customer profiles. PlusSales, on the other hand, uses AI to analyze existing store analytics data, primarily from GA4, and identify potential conversion rate optimization (CRO) opportunities. It automates the research phase of A/B testing by generating hypotheses and implementation specs for platforms like VWO and Optimizely. This app is geared towards data-driven merchants looking to optimize their website's user experience and increase conversion rates through structured testing, streamlining the often tedious initial research phase of CRO.

Our Verdict
Grapevine Post Purchase Survey is the better choice for merchants prioritizing understanding customer sentiment and improving customer experience through direct feedback. Its unlimited responses and integrations provide a comprehensive view of the customer journey. It's well-suited for businesses who value customer satisfaction as a key performance indicator.
PlusSales ‑ AI A/B Testing, while also highly rated, is more niche. It's ideal for merchants already familiar with A/B testing principles and using GA4 extensively who want to automate the initial research phase and generate data-backed hypotheses. The low number of reviews suggests it might be newer or targeting a more specialized audience. Choose PlusSales if you're focused primarily on conversion rate optimization and have a strong A/B testing framework in place.
