What is REP AI?

REP AI, at hellorep.ai, is an ecommerce AI platform with Sales, Support and combined Concierge offerings. Its sales tools use shopper behavior to decide when to offer help, recommend products and guide purchases. It also offers conversational search and cart assistance. See REP's sales features.

REP's support documentation describes cancellations, address updates, eligible order edits, returns, damaged-item claims and Recharge subscription management. Actions depend on enabled skills, permissions, connected services and store policies. Its knowledge sources include the catalog, help-center content, URLs and FAQs, with approved learning from human support replies. See REP's support features.

REP also connects to helpdesks such as Gorgias, Zendesk and Freshdesk for human handoff. Its own Rep Inbox provides a separate helpdesk option with ticket routing and AI draft suggestions. See REP integrations and Rep Inbox.

Why choose Flyweight as your REP AI alternative?

Flyweight combines flexible AI capacity with the store knowledge and workflows your team already uses. These are the practical reasons to choose it:

• Grow traffic without paying for every eligible visit. Flyweight has no session meter, so a successful campaign does not increase AI charges just because more people browse.
• Choose a predictable unlimited budget. Stores of any size can agree a fixed price for unlimited AI interactions, products and Copilot Seats.
• Use the same Shopify knowledge across channels. AI Chat, AI Search, social messaging and Ticket AI drafts draw on your store's Knowledge Graph.
• Keep your existing helpdesk. Ticket AI (Beta) brings store-grounded drafts into supported tools instead of requiring an inbox migration.
• Get setup tied to measurable value. Eligible stores above $500,000 in annual revenue can choose managed setup with an ROI guarantee under agreed written terms.

REP AI vs Flyweight pricing: pay for AI, not every visit

More visitors should not have to mean a higher AI bill. Flyweight has no visitor-based charge: a traffic spike by itself does not consume your AI allowance. If you also want to remove AI usage overages from the equation, choose an individually agreed unlimited plan.

How REP AI pricing works

REP's current pricing page lists monthly starting prices for up to 3,000 website sessions: $39 for Sales, $19 for Support and $46 for Concierge. Higher traffic tiers, annual billing and add-ons change the quote. Its published trial is 14 days.

A billed REP session is a shopper's device visiting on a calendar day in UTC where the widget is shown. The shopper does not need to open the chat or receive a proactive message. Known bots, visits where the widget is hidden and other specified exclusions do not count. See REP's billing-unit explanation.

An illustrative example: 10,000 eligible sessions with only 100 shoppers using AI still count as 10,000 REP sessions, not 100. Flyweight counts the AI responses used, or covers them under your agreed unlimited plan. That difference matters for high-traffic stores with relatively few AI users.

Email and social AI use a separate resolution-based add-on; Rep Inbox adds ticket-tier and agent charges. Check the selected plan's product limits, session overages and channel allowances before estimating a peak month.

How Flyweight pricing works

Flyweight's standard paid plans have a monthly base price and an included AI-interaction allowance:

• AI Starter: $49/month, including 500 AI interactions, 3,000 products and 1 Copilot Seat (Beta). Standard overage: $15 per 100 additional AI interactions.
• AI Pro: $129/month, including 1,300 AI interactions, 10,000 products and 3 Copilot Seats (Beta). Standard overage: $30 per 200 additional AI interactions.
• AI Leader: $299/month, including 3,000 AI interactions, 30,000 products and 5 Copilot Seats (Beta). Overage: $60 per 300 additional AI interactions.

AI interactions count AI-generated responses across connected channels, including AI Chat, AI Search and Copilot. Customer messages and human replies do not consume that AI allowance. Pro and Leader support additional products at $5 per 1,000 products per month. Premium AI options on Starter and Pro change the applicable overage terms; confirm the selected configuration when comparing Flyweight plans.

Unlimited plans are available for every store size. Agree a fixed price for unlimited AI interactions, products and Copilot Seats with our team, then grow traffic and AI usage without a visitor meter or interaction overages under that plan. Schedule a demo to discuss your quote. The standard plans above remain an option with defined allowances and overages.

For eligible stores above $500,000 in annual revenue, Flyweight also offers managed setup with an ROI guarantee. Our team handles the agreed setup and measures the results against goals defined together. If the AI does not pay for itself during the agreed three-month evaluation, you pay nothing for that evaluation under the written guarantee terms.

Eligible stores receive a seven-day free trial of a paid plan, with existing partner extensions preserved. The managed ROI offer is agreed separately; installing the app or starting a trial does not activate it.

One Shopify knowledge base across your AI channels

Flyweight builds a Knowledge Graph connecting your Shopify content. The same store knowledge supports AI Chat, AI Search, social conversations and Ticket AI drafts. Your team can bring product advice and support into more channels without maintaining a separate AI knowledge base for each one. Paid plans refresh knowledge automatically each night from products, pages, blog posts and store policies.

For example, a shopper might ask whether a product fits their use case, ships to their country and can be exchanged after a promotion. Flyweight can bring the relevant product information and policies into one conversation, helping the shopper make a decision. That connected knowledge also gives your support team a useful starting point when drafting a reply in the helpdesk.

Turn Shopify product questions into buying decisions

Flyweight helps shoppers describe what they need, compare products and understand the details that matter before checkout. AI Search and AI Chat work from the same store knowledge, so discovery and advice connect naturally. Proactive popups can start the conversation, while relevant recommendations, forms and Quick-Actions help shoppers take the next step.

REP also offers behavioral sales engagement and shopping assistance. Flyweight's appeal is the combination of guided product advice, connected support and no visitor-based billing. You can send more traffic to a product launch without adding a charge for every shopper who simply browses.

Resolve routine requests and keep your existing helpdesk

Flyweight can handle order tracking and configured cancellation or address-change requests, while routing other cases to your returns portal, a form or your team. The conversation can lead to an action or a clear next step, with permissions, order eligibility and customer verification defined for your store.

For the conversations your team handles, Ticket AI brings the same knowledge into Gorgias, Zendesk, Freshdesk, Gmail and Outlook on the web. The Copilot browser extension drafts a reply beside the existing inbox; your team reviews and sends it. Keep the tools and ticket history you already have, and add AI help where your team works. Ticket AI is in beta; access, setup and Copilot Seat allowances apply.

REP supports connected-helpdesk handoff and offers Rep Inbox as a separate helpdesk option. Flyweight's drafting workflow is especially useful when your existing helpdesk already fits your team and you want store-grounded AI assistance inside it.

Who should choose REP AI?

REP AI is worth shortlisting if your team wants behavioral sales engagement, a broad set of packaged post-purchase skills and the option to use REP's own helpdesk. Model its session tiers and channel add-ons against your expected traffic before choosing a plan.

Choose Flyweight for connected Shopify AI and a budget you control

Flyweight brings product advice, search, social messaging and helpdesk drafts together around your Shopify knowledge. No visitor-based billing means your audience can grow without a session charge. Choose a standard interaction allowance or an individually quoted unlimited plan for a fixed AI budget, available to every store size.

For eligible stores above $500,000 in annual revenue, managed setup pairs implementation help with a clear commitment: the AI must pay for itself against the agreed criteria, or you pay nothing for the three-month evaluation under the written guarantee. Schedule a demo to discuss the knowledge, actions and handovers your store needs.

How to switch from REP AI to Flyweight

Install Flyweight and test it in preview using representative product, policy and support questions. Check catalog coverage, order-action permissions and human handovers before publishing the widget. Setup time depends on the catalog and the workflows being connected.

When switching the storefront, disable the old widget so customers see one chat entry point. If you run a comparative trial, split comparable traffic deliberately instead of showing both widgets to the same shopper. Keep any helpdesk your team still needs, and check the outgoing subscription's cancellation terms separately.
