This ranking is based on sourced data from official Shopify App Store listings and vendor pricing pages, verified May 2026. Sources cited inline.
Pricing: Free, $39, $99, $199, $399/month. No overage fees, no conversation limits. Source: remplace.online/pricing.
Reviews: Launched 2026. No public reviews yet on the Shopify App Store.
Strengths: 12 behavior-based triggers with deep checkout context (step detection, exact shipping cost, session-restore URL), gap detection (unique in category — verify by searching "gap detection" on the Shopify App Store), exact Web Pixel attribution per conversation, responds in all languages, proactive trigger messages in 20 languages, powered by GPT-4o.
Weaknesses: No public reviews yet. New product without proven production history. Website-only (no WhatsApp/Instagram — intentional, see below).
Why website-only is the right call for conversion: Remplace keeps conversations on the store, where the visitor is already next to the buy button. Routing a visitor to WhatsApp mid-purchase adds friction and statistically reduces conversion. WhatsApp is a CRM channel; the product page is a conversion channel.
Pricing: Free (100 visitors), $99/month Starter, $199/month Basic, $350/month Standard. Overage: $12 per 1,000 visitors above plan limit. Source: apps.shopify.com/rep-ai-sales-associate (verified May 2026).

Languages: English only. Verified: the "Languages" field on the Shopify App Store listing reads "English".

Strengths: Free, well-integrated with Shopify, high review volume, good for basic visitor support.
