HeiChat review: a Shopify-first AI chatbot that answers from your own catalog

A shopper lands on your store, can't tell whether a jacket runs small, and leaves. That moment — the unanswered sizing, shipping, or stock question — is where a lot of ecommerce revenue quietly leaks out. HeiChat is built for exactly that gap: an AI chat widget that reads your products and policies and answers buyers in the moment, instead of leaving them to guess or email.

It's made by GenCybers Inc. and leans hard into the Shopify ecosystem, though it also runs on WooCommerce and custom storefronts. If you've tried bolting a generic chatbot onto a store before and pulled it back off because it made things up, HeiChat's whole pitch is that it stays closer to your actual data.

What HeiChat handles

HeiChat is a no-code assistant you train on your own store. You connect the storefront, sync your products, policies and any supporting documents, review how the bot answers, then push it live. The result is a widget that handles the repetitive pre-sale and post-sale questions: shipping timelines, return rules, stock, sizing, order tracking, and product discovery ("which of these is waterproof?").

Two things make that more than a canned FAQ. First, it grounds answers in your catalog and knowledge base rather than general internet knowledge, which is what keeps it from inventing a return window you don't offer. Second, it supports more than 70 languages, so a store taking international traffic can answer an Arabic or French customer without running a separate support process. There's also an analytics view that surfaces what people keep asking and where conversations stall, which doubles as a quiet list of gaps in your own product copy.

Under the hood it isn't locked to one model. HeiChat runs on OpenAI's GPT-3.5 and GPT-4 and on Anthropic's Claude 3 Opus, and it lets you switch between them; the top tier even lets you bring your own OpenAI API key.

Setup and where it runs

The install story is genuinely three steps, and Shopify is the path HeiChat recommends first — it's a native app install with the least friction. WooCommerce merchants get a WordPress plugin, and there's a website version for custom stores, though HeiChat positions those as secondary rather than the main event. If you're on Shopify this is a same-afternoon job; if you're on a bespoke stack, expect to do a little more of the wiring yourself.

One detail worth flagging before you commit: the pricing published on the site is the Shopify pricing, and HeiChat says plainly that website and other installs can follow a different pricing path. Confirm your numbers for your platform before you plan a budget around them.

How the pricing works

HeiChat's Shopify plans are metered in tokens rather than a flat seat price, which is the part that rewards a close read. The tiers:

• Free: free to install, 800k tokens, 100 products, 20 knowledge bases.
• Pro: $29.90/month — 500 products, 100 knowledge bases, 10M tokens/month, 250 AI replies/month, with a 3-day trial.
• Pro Plus: $69.90/month (the one HeiChat marks most popular) — 3,000 products, 1,000 knowledge bases, 50M tokens/month, 1,250 replies, plus live-chat, WhatsApp and Messenger integration.
• Pro Max: $299/month — 20,000 products, 3,000 knowledge bases, 400M tokens/month, 10,000 replies, and the option to use your own OpenAI key.

Every tier charges $1 per 200k tokens once you go over the monthly allowance. For a store with steady, moderate traffic that's predictable enough. For a store that suddenly goes viral — or one that attracts a lot of low-intent chatter — the bill moves with volume, and that's a different planning exercise than a fixed subscription. One merchant review on HeiChat's own page makes the same point: the app earns its keep, but cost management needs watching as request volume climbs.

What independent reviews say

On the Shopify App Store, HeiChat holds a 4.9 rating with 89% of ratings at five stars, across a base HeiChat describes as 1,500-plus stores. The recurring theme in those reviews is reliability: merchants who had tried several AI chatbots and abandoned them in testing — over hallucinations, drift, or constant babysitting — report that HeiChat was the one they actually left running in front of customers. Others cite concrete outcomes, like a store that saw customer emails drop by roughly half after turning it on, and another reporting a double-digit lift in sales. Those are self-reported numbers, not audited, so read them as direction rather than guarantee.

The reviews aren't uniformly glowing. At least one merchant reported the bot "forgot everything it learned" and briefly became useless until support stepped in — a reminder that a trained AI assistant is a system you maintain, not a set-and-forget appliance. HeiChat's support gets consistent praise for responsiveness, which matters more than usual when the product is this dependent on its knowledge base staying intact.

Who it fits

HeiChat is a clean fit for a small or lean Shopify team that fields the same product and policy questions all day and wants to answer them at any hour, in multiple languages, without hiring overnight coverage. It's also a reasonable pick for international stores where language support is the actual bottleneck. It's a weaker match if you're not on Shopify (you lose the smoothest install and the published pricing certainty), or if your support is mostly complex, judgment-heavy cases rather than lookups — an AI that's great at "where's my order" is not a substitute for a human handling a damaged-shipment dispute.

HeiChat points to Baymard Institute research that roughly a quarter of shoppers abandon when they can't find a product or get a fast answer. If that describes your store's drop-off, this is a targeted fix rather than a broad platform.

Verdict

HeiChat does the specific thing it promises well: it answers store questions from your own data, on the platform most of its users are already on, with a track record and a review profile that back up the claims. The token-metered pricing and the maintenance the knowledge base needs are real considerations, not dealbreakers. Overall it's a 4/5 — a dependable, well-reviewed choice for Shopify merchants, with the usual caveat to watch your usage and keep its training current.
