Phia vs XInfer Web App

Phia is an AI shopping agent that finds products across 220,000+ sites and compares prices across retailers and resale sites. It can surface cheaper alternatives and automatically apply coupon codes at checkout. Users can save finds in collections, get alerts when prices drop, and earn points on purchases to redeem for gift cards. Price comparisons include a network of over 150 resale partners; Phia says those partners authenticate goods and disclose their practices. Purchases take place on partner websites, and Phia directs users there rather than handling transactions. On mobile, its iOS app guides users through adding the extension to Safari; on desktop, the extension is available through the Chrome Web Store. The listed free plan is free, and the iOS app and Chrome extension are described as free. Phia says it does not store users' personal or financial data on its system. It lists [email protected] for assistance and feedback.

XInfer Web App is a browser-based shopping assistant for product discovery, recommendations, ordering, and delivery tracking. Shoppers can ask questions by chat or voice, search a catalog, filter categories, and review product images, descriptions, prices, and availability. They can add items from product pages or conversations, change quantities, and check out in the browser. Order history and tracking cover processing, shipping, and delivery; customers can also choose a business location to view its catalog and pricing. The app works in modern desktop and mobile browsers without an install to begin chatting, and is listed for Android and iOS. Shopify stores can sync products and use draft-order checkout with invoice links. Other stores can route order details to an external system through a webhook. The maker says customer content is not used to train general AI models and is sent to third-party AI providers only to generate responses. The privacy policy describes customer data separation, TLS 1.3 in transit, AES-256 at rest, role-based controls, and SOC 2-compliant cloud infrastructure. Conversation history is retained according to customer configuration, with a 90-day default; technical logs are retained for 30 days. Plans include a free tier and paid options from $39 a month.
