What is Zubby AI vs Rep AI at a glance?

Rep AI and Zubby AI are the two most similar tools in this comparison set: both run a catalog-grounded AI concierge on the storefront, proactively nudge hesitating shoppers, recommend products in-chat, and sync your catalog in minutes. Rep AI is the more established of the two — a longer track record, a deep G2 review base, public revenue case studies, deeper agentic-checkout, and an AI that coaches human support agents. Zubby is broader and built for measurement: it's native on Shopify AND WooCommerce, adds an off-site recovery-email + multi-step journey engine, an omnichannel inbox (WhatsApp / Instagram / Facebook / email), reviews + loyalty, a Thompson-sampling bandit on the chat surface, and holdout-RCT attribution that proves AI-driven revenue against a randomized control. Shopify-only stores that want the most proven onsite agent should look hard at Rep AI; stores on WooCommerce — or anyone who wants recovery, omnichannel, and provable lift in one flat-priced tool — fit Zubby.

  • Rep AI wins on

    Track record + reviews, agentic-checkout depth, human-agent coaching.

  • Zubby wins on

    Shopify + WooCommerce native, recovery email + journeys, holdout attribution, flat pricing.

  • Both do well

    Catalog-grounded chat, proactive nudges, in-chat add-to-cart, fast catalog sync.

  • Honest gap

    Zubby is newer — fewer public case studies and less proven scale than Rep AI today.

What Rep AI does well

Rep AI is the closest thing we have to a direct competitor, and it earns that position. Four things Rep AI genuinely does well:

  • Track record and social proof. Years in the Shopify ecosystem, a large G2 review base, and public revenue case studies. For a category where trust is the hard part, that history is a real asset Zubby can't yet match.
  • Agentic-checkout depth. Rep AI has leaned into agentic commerce — the agent driving more of the purchase itself — earlier and deeper than most onsite agents.
  • Human-agent coaching. Beyond the shopper-facing bot, Rep AI includes an ML layer that trains and scores human support reps. Zubby doesn't have an equivalent.
  • Mature, fast Shopify onboarding. Connect the catalog and go live in minutes, polished by years of iteration on the Shopify install path.

Where Rep AI falls short

Rep AI is an excellent onsite agent. The limits show up when you need the platform reach, the off-site recovery layer, or the measurement rigor that turns a chatbot into a Conversion OS. Four gaps:

  • Shopify-centric. If you run WooCommerce, Rep AI isn't built for you. Zubby ships a native Woo plugin with the same AI agent, catalog/knowledge sync, and verified customer login.
  • On-site only. Rep AI lives in the storefront conversation. It doesn't own an AI-written recovery-email engine, a browse-abandonment cron, or a multi-step journey builder the way Zubby does — the saves that happen after the visitor leaves.
  • No holdout RCT attribution. Rep AI reports influenced revenue, but without a randomized control cohort it's hard to defend the number to a skeptical CFO. Zubby runs a true holdout so the lift is causal, not correlational.
  • Session-metered pricing. Billing scales with website traffic plus a per-1,000-visitor overage on every tier, so a spike inflates the bill for visitors who never convert. Zubby is flat per tier.

Why merchants pick Zubby

When a store chooses Zubby over Rep AI, it's usually one of three triggers:

  • They're on WooCommerce. The single clearest reason. The same agent that runs on Shopify runs natively on Woo — Rep AI doesn't cover that.
  • They want one tool, not three. Onsite agent + recovery email + journeys + omnichannel inbox + reviews + loyalty in one subscription, instead of an onsite agent plus a separate email tool plus a separate helpdesk.
  • Finance wants proof. The holdout dashboard shows AI-attributed revenue against a randomized control, on a flat bill that doesn't balloon when traffic spikes.

Pricing comparison

Per-session metering vs flat per-tier

Rep AI

  • Tiered by website sessions (~$79 / $159 / $239 for 10k / 25k / 50k).
  • $12 per additional 1,000 visitors — on every tier.
  • Traffic spikes inflate the bill for non-converting visitors.
  • 30-day trial + 60-day money-back guarantee.

Zubby AI

  • From $49/month, flat per tier — no per-session metering.
  • No per-AI-resolution fees stacked on top.
  • Enterprise tier adds SSO, audit log, named CSM, 99.99% SLA.
  • Aligned with revenue, not raw traffic.

When to choose each

They overlap more than any other pair in this set. The deciding factors are platform, suite breadth, and how you want to be billed.

Pick Rep AI if

You want the most proven Shopify-native agent

  • You're Shopify-only and value a long track record + review base.
  • Agentic, agent-driven checkout is a headline requirement.
  • You want AI that also coaches your human support reps.
  • Off-site recovery email and journeys aren't part of the brief.

Pick Zubby AI if

You want reach, recovery, and provable lift in one tool

  • You run WooCommerce — or both Woo and Shopify.
  • You want recovery email + journeys + omnichannel inbox in one subscription.
  • Holdout RCT attribution and per-module revenue is a CFO ask.
  • You'd rather pay flat per tier than per session with spike overage.

Migration

Switching from Rep AI? Here's how

A four-step migration script. Most stores are live on Zubby AI within a single afternoon — no data loss, no agent retraining, no downtime for your existing tooling.

1

Connect the storefront

Install the Shopify app or WooCommerce plugin. OAuth handles auth — no API keys to copy. Your catalog and historical orders sync via Bulk GraphQL or REST in minutes.

  • Theme App Extension installs the widget without code edits
  • Existing analytics keeps running while you A/B the agent
2

Import your knowledge

Upload help-center articles, shipping policies, sizing charts, and FAQs. Our embedding pipeline indexes them with citations so the agent answers from your real content, not training data.

  • Pull from a public site URL or upload PDFs / DOCX directly
  • Reranker promotes the right doc for each query, every time
3

Rebuild your flows

Replicate your most-used journeys: abandoned cart, browse abandonment, win-back, and welcome. Use our pre-built templates or start from a blank canvas.

  • Triggers cover idle abandonment, exit intent, policy friction, repeat visits
  • Send via email today, layer SMS / WhatsApp / Klaviyo when ready
4

Run side-by-side, then cut over

Keep your existing tool live until you've seen AI-attributed revenue cross plan cost. The dashboard makes the lift unambiguous so the switch is a numbers decision, not a feeling.

  • Flat monthly pricing — no per-resolution fees
  • Export raw events via the public API any time

Switching agents is low-friction: there are no macros or ticket rules to migrate. Connect your catalog, run Zubby alongside Rep AI, and let the holdout dashboard decide — keep whichever proves more lift.

Illustrative quote · representative of merchant feedback in trials

“We trialed both on the same storefront for a month. Rep AI held its own on the chat — they've clearly been at this a while. We went with Zubby because half our revenue is on WooCommerce, and the holdout number was the tie-breaker finance actually trusted.”

FAQ

Frequently asked questions

Is Rep AI or Zubby AI the better AI sales agent?

They're the closest peers in this category — both are catalog-grounded AI sales concierges that sit on the storefront, nudge hesitating shoppers, and recommend products in-chat. Rep AI is the more proven of the two: years in market, a deep G2 review base, and public revenue case studies. Zubby is broader: it's native on Shopify AND WooCommerce, adds an off-site recovery-email + journey engine, an omnichannel inbox, reviews/loyalty, holdout RCT attribution, and flat per-tier pricing. If you're a Shopify-only store that wants the most proven onsite agent, Rep AI is a strong pick. If you want one tool that also covers Woo, recovery, and measurement, Zubby pulls ahead.

Does Rep AI work on WooCommerce?

Rep AI is built around the Shopify ecosystem — its catalog sync, agentic checkout, and app distribution are Shopify-centric. Zubby ships a first-class WooCommerce plugin (catalog + knowledge sync, webhooks, storefront widget, verified customer login) alongside the Shopify app, so the same AI agent runs natively on both platforms. For a Woo store, that's the clearest reason to choose Zubby.

How does pricing compare?

Rep AI meters on website sessions — roughly $79/mo for ~10k sessions, $159 for ~25k, $239 for ~50k, with a $12-per-additional-1,000-visitors overage on every tier. That means a traffic spike (a sale, a viral post, a bot wave) can inflate the bill for visitors who never buy. Zubby is flat per tier from $49/mo — you don't pay per session or per AI resolution. Verify both live: Rep AI's pricing page and our /pricing.

Can Zubby do agentic checkout like Rep AI?

Rep AI leans hard into agentic commerce and has more depth there today. Zubby does in-chat add-to-cart, applies merchant-approved checkout discounts via a Shopify cart-transform, and ships an agentic-commerce (ACP) scaffold — but we deliberately keep money actions (refunds, cancellations) out of the AI's hands and route them to a human ticket. That's a trust/compliance design choice, not a missing feature: the AI sells and assists, humans move money.

Should I switch from Rep AI to Zubby?

Switch if you need WooCommerce support, want recovery email + journeys + omnichannel inbox in the same tool, or your finance team wants a randomized holdout to prove AI-attributed revenue. Stay on Rep AI if you're Shopify-only, value its longer track record and review base, and use its agent-coaching for a human support team. Many of the capabilities overlap, so the decision usually comes down to platform (Woo?), suite breadth, and how you want to be billed.
