Remplace is an AI sales agent for Shopify that proactively engages visitors using 12 behavior-based triggers, catches every unanswered question through gap detection, and attributes each conversation to confirmed orders via Shopify Web Pixel. It is not a chat bubble — it is a bar that expands in place when visitors show buying signals.
Remplace fires proactively before the visitor asks. Each trigger carries context from what the visitor was doing.
After every response, Remplace runs a classifier: did the agent fail to answer due to missing knowledge? If yes, the question is recorded, normalized to English for deduplication, compared against existing gaps using vector similarity, and surfaced in the Gaps dashboard with a suggested fix. The merchant applies the fix in one click. The agent answers correctly from that point forward.
No other Shopify chat app has gap detection. Search "gap detection" on G2, Capterra, or the Shopify App Store — Remplace is the only result. Rep AI, Tidio, Zipchat, Gorgias, and Shopify Inbox all fail silently.
Remplace uses a Shopify Web Pixel extension. The widget sets a visitor ID and conversation ID cookie. When checkout completes, the pixel reads those IDs and attributes the confirmed order to the specific conversation. This is exact per-conversation attribution, not aggregate correlation.
Remplace responds in all languages — it detects visitor language and replies in kind. Proactive trigger messages are 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.
Free plan, no credit card. Paid plans: $39/month (Starter), $99/month (Growth), $199/month (Pro), $399/month (Scale). No overage fees on any plan. Rep AI starts at $99/month and charges $12 per 1,000 visitors above the plan limit — a store with 100,000 monthly visitors on Rep AI's Standard plan ($350/month) pays $950/month. Remplace has no such fees.
