Kauthar AI for OpenCart
One extension adds Kauthar's chat bubble to your OpenCart store and shares your catalog with her, so your AI assistant answers with your real products, prices and stock.

What you get
Chat bubble on your OpenCart store
The extension adds Kauthar's chat bubble to your OpenCart storefront, without touching your theme files. Switch it off at any time.
Answers from your real catalog
Kauthar reads your OpenCart products — names, prices, stock and options — and answers with product cards that link to the product page.
Product changes in minutes
When a product changes on OpenCart, Kauthar re-syncs it within minutes — and checks the whole catalog again every day.
Read only, signed requests
Kauthar can only read your catalog. Every request is signed with a secret that only your store and Kauthar know, and replays are refused.
One assistant, every channel
The same knowledge answers on your website, chat link and QR code, WhatsApp, Messenger, Instagram and Telegram.

FAQ
Is the OpenCart integration free?
Yes. Installing it costs nothing and it is included in every Kauthar plan. New businesses start with a 14-day free trial, no credit card needed.
What does Kauthar read from my store?
Your products only: name, description, price and special price, stock, options or variants, categories, images and links. This version of the OpenCart integration does not read orders or customers.
Will Kauthar change anything in my store?
No. The OpenCart extension only lets Kauthar read your catalog — it never writes to your store.
How fast do product changes show up?
Within minutes: OpenCart tells Kauthar when a product changes, and the whole catalog is checked again every day.
Which languages does Kauthar reply in?
Kauthar detects the language of each customer message and replies in it — Arabic (in the style you choose), English, French and more — without translating your catalog.
Can I disconnect?
Yes, at any time: remove the store in Kauthar → Connect your store, or uninstall the plugin or app. Its keys are deleted and syncing stops.
Is my data — and my customers' — safe?
Each business sees only its own data, it is stored on our servers in Frankfurt, Germany, and we don't sell it. Kauthar writes replies with a cloud AI model from Google (Gemini) under Kauthar's own account: to write each reply, the customer's message, the recent conversation and the parts of the business's information it needs are sent to Google, which processes them on our behalf; if that service can't be reached, a backup model on our own servers answers. On the Business plan you can instead connect your own OpenAI, Anthropic or Google account. Our Security & trust page lists every measure in place.
