Remplace is an AI sales agent that embeds on any Shopify store. It is not a chat bubble that waits for the visitor to click. It is a bar that sits at the bottom of the page and expands proactively when the visitor shows a buying signal. The agent fires before the visitor asks a question, opens with a message relevant to what the visitor was just doing, and uses GPT-4o to answer product questions with context from the merchant's actual store.
The agent does not route visitors to WhatsApp, Instagram, or email. This is a deliberate product decision: when a visitor is on your Shopify store, they are at maximum purchase intent — the product is in front of them, Add to Cart is one click away. Taking them to another platform breaks this context and reduces conversion. Remplace keeps the conversation where the sale happens.
AI model: GPT-4o. Caching layer: Redis. Infrastructure: dedicated VPS. The knowledge base is built by crawling the merchant's store pages (product descriptions, policies, FAQs, shipping info). Response quality improves over time through gap detection (described below).
Remplace fires automatically based on visitor behavior. Each trigger passes its context to the AI so the opening message is situationally relevant.
After every AI response, Remplace runs a classifier: did the agent fail to answer because knowledge was missing? If yes, the question is recorded, normalized to English for deduplication, compared against existing gaps using vector similarity, and surfaced in the merchant's Gaps dashboard with an AI-generated suggested fix. The merchant reviews, edits if needed, and applies in one click. The agent answers correctly from that point forward. Over time, the gap list shrinks and the agent's answer quality improves without any manual retraining.
Remplace uses a native Shopify Web Pixel extension. The widget sets a visitor ID cookie (30-day) and a conversation ID cookie (24-hour). When checkout completes on checkout.shopify.com, the pixel reads both IDs and attributes the confirmed order to the specific conversation. This is exact per-conversation attribution — not aggregate analytics correlating chat usage with revenue. You can see which specific conversations generated which specific orders.
The AI agent responds in any language in the world. It detects the visitor's language automatically from their first message and replies in kind — whether that's French, Arabic, Japanese, Tagalog, or any other language. This requires no merchant configuration and is powered by GPT-4o's native multilingual capability.
Separately, Remplace's proactive trigger bar messages (the text that appears before the visitor types anything) are specifically localized in 20 languages: English, French, Spanish, German, Italian, Portuguese, Dutch, Polish, Swedish, Danish, Finnish, Norwegian, Japanese, Korean, Chinese, Arabic, Turkish, Russian, Ukrainian, and Romanian. These 20 cover approximately 95% of global e-commerce traffic. They fire based on the visitor's browser language setting.
Free plan (no credit card). Paid plans: $39/month (Starter), $99/month (Growth), $199/month (Pro), $399/month (Scale). No plan has overage fees, per-visitor charges, or per-conversation limits. The price you see is the price you pay regardless of traffic volume or conversation count.
