Direct answer: the best PrestaShop chatbot depends on one question. Do you want it to read your live catalogue and orders, or to answer from your own content (shipping policy, returns, FAQ, product pages)? For live catalogue, stock and order tracking, an Addons Marketplace module such as Emporiqa, AI SmartTalk or Knowband is the right route. To take the repetitive support load off your inbox without touching the back office, a script-based SaaS such as Heeya is enough, with a flat monthly price and EU storage.
On PrestaShop, "chatbot" covers three different things: modules sold on the Addons Marketplace and installed in the back office, live chat platforms with an optional AI layer, and AI agents you plug in with one line of JavaScript. All three say "AI". The mechanism, the cost and the risk to your store differ a lot.
This guide ranks 7 options on what matters to a merchant: what the bot can do, what it really costs (licence, subscription, API key), and the risk it adds to your shop. Heeya is our product; we assessed it with the same criteria as the others. Where a competitor is better for a use case, we say so. Prices checked in November 2026.
Quick verdict
- Best for answering policy and product questions at a flat price: Heeya, trained on your pages and documents, installed by script
- Best for live catalogue and product advice: Emporiqa, an Addons module that reads stock and combinations
- Best for orders plus documents on a small budget: AI SmartTalk, from €9.90/month
- Best for a human team with AI support: Crisp or Tidio
Addons Module or Script-Based SaaS: The Real Choice on PrestaShop
Before comparing brands, decide how the chatbot gets onto your store. The two routes have different strengths and different risks.
The Addons Marketplace module
You buy or download a module from the PrestaShop Addons Marketplace, install it in the back office and configure it. Its big advantage: it lives inside PrestaShop, so it can read the catalogue, combinations and sometimes stock and order status.
The constraints are those of any PrestaShop module: compatibility with your version (1.6, 1.7, 8.x or 9.x), multistore support, theme and module conflicts, updates to track. Read the listing before you buy: supported version, last update date, download count. The free "Chatbot par Botnation" module, for instance, showed compatibility with 1.6 to 8.2 and a last update in January 2024, according to a September 2026 review on chatbot.fr.
The script-based SaaS
You build the agent on the vendor's platform, train it on your content, then paste one script line into your theme (footer.tpl or a code-injection module). Nothing is installed in PrestaShop core, so there is no version conflict. It runs on any version and across several shops.
Heeya answers from your content (terms, FAQ, product pages, returns policy). That covers most repeat questions; for real-time order tracking ("where is order #4521?"), a module connected to the PrestaShop database such as Emporiqa, AI SmartTalk or Knowband is better suited. For the support pain behind that choice, see our piece on why PrestaShop customer service modules fall short.
What a Chatbot Can Do on a PrestaShop Store
A PrestaShop shop gets mostly the same questions over and over. An AI chatbot handles some well and others less well. Here is a realistic split.
What a chatbot trained on your content covers
- Shipping: delivery times, carriers, costs, countries served, pickup points, drawn from your shipping page and terms.
- Returns and refunds: withdrawal period, procedure, return costs, excluded products.
- Product questions: materials, dimensions, compatibility, care, taken from product pages and guides.
- Payment and invoicing: accepted methods, instalments, invoices, VAT.
- Contact capture: when the answer is not in your content, offer a form instead of guessing.
What needs a connection to the shop database
Tracking a specific order, real-time stock, the price of one combination, or recommendations based on the whole catalogue all require reading the PrestaShop database. That is the territory of catalogue-connected modules and of some support tools with an order connector. If these requests dominate your inbox, it is a deal-breaker criterion.
The shared risk: an invented answer
A language model plugged straight into a catalogue can state a delivery time or a return condition that does not exist. In the EU, a wrong answer on the 14-day right of withdrawal is not trivial. RAG (retrieval-augmented generation) agents reduce that risk by answering from specific passages of your documents. Our business guide to RAG explains the mechanism.

1. Heeya: A RAG Agent by Script, Built to Clear the Support Inbox
Heeya is an AI chatbot trained on your content: web pages imported by scraping, PDF, DOCX, PPTX, TXT, or Q&A in xlsx/csv. On a PrestaShop store you feed it the shipping page, terms and conditions, returns policy, FAQ and product pages. It answers from those passages and nothing else.
Strengths:
- Flat pricing: Standard €19/month (500 messages, 1M characters, 1 agent), Premium €99/month (2,500 messages, 3M characters, 3 agents), Enterprise on quote. A 7-day free trial with no card lets you test on your own pages. See the pricing page.
- Script install: one line in the theme, no module to maintain, independent of your PrestaShop version.
- Built-in tools: a contact form that captures a lead when the answer is missing; on Premium, support tickets and appointment booking; an answer reliability score.
- French and English: the widget follows the page language.
Data: Heeya stores conversations and knowledge bases in the EU (OVH, France); message content is sent to AI providers (Google, OpenAI) that may process it outside the EU under standard contractual clauses or the Data Privacy Framework, with no training on your data. A signed processing addendum is available on request.
Good to know: Heeya is built so the AI agent answers on its own from your content (terms, FAQ, product pages, returns policy). For real-time order tracking, a module connected to the PrestaShop database such as Emporiqa, AI SmartTalk or Knowband is better suited, and if your team wants to reply live in the widget, Tidio or Crisp are a better fit. Heeya works in French and English, and its list of integrations is shorter than Tidio's or Crisp's.
Best for: a store whose support is dominated by shipping, returns, payment and product questions that are already written down somewhere.
2 to 5. Modules and Tools That Read Your Catalogue
These four live inside PrestaShop and read shop data. That is their decisive advantage for order tracking and product recommendations.
2. Emporiqa: the module built to sell
Emporiqa has an official Addons module for PrestaShop 8.x and 9.x. It reads the live catalogue, including combinations and stock, and shows order status. It is priced per conversation: $0.25 each, with a $25 starting credit and a monthly spending cap you set (default $199). Answers are generated through OpenAI's US infrastructure.
Takeaway: excellent when product advice on a rich catalogue is the priority. The bill follows traffic: at 2,000 conversations a month, expect $500.
3. AI SmartTalk: module with order sync
AI SmartTalk ships its own PrestaShop module that syncs products and orders. Plans on its pricing page: €9.90/month (1M "AI Words", 250 documents, 1 assistant), €29/month (5M, 1,000 documents, 2 assistants), €79/month (15M, 10,000 documents, 5 assistants), Enterprise €499. 30-day trial, no card. Higher tiers add channels such as WhatsApp and Messenger.
Takeaway: the best compromise if you want documents and order lookups together at a low entry price.
4. Knowband: one-time licence, your own API key
Knowband sells a native module that works with GPT-4o, DeepSeek, Gemini or Claude through your own API key. It does product search and comparison and order tracking, supports several languages and currencies, and keeps chat logs. The licence price is on the Addons listing; API consumption is extra.
Takeaway: attractive if you are comfortable with an API key and a variable bill. Monitoring usage, and checking what you send to the model provider, is on you.
5. Smart IA Chatbot: a simple module on top of an API
Smart IA Chatbot (Gemini and OpenAI) is sold at €83.99 excl. VAT on the Addons plus €2/month for support, compatible with PrestaShop 1.6 to 9.1, according to chatbot.fr (4.6/5 from 16 reviews, 1,173 downloads at the time). The OpenAI or Gemini API is billed separately.
Takeaway: a low entry cost and very wide version support, useful on an older 1.6 or 1.7 store. Test answer quality on your own terms before going live.
6 and 7. Crisp and Tidio: Live Chat With AI
6. Crisp: the inbox that assists your team
Crisp is a French platform built around a shared inbox. Its pricing is per workspace: a free plan (2 seats, no AI credits), $45/month (Mini, 4 seats), $95/month (Essentials, 10 seats, AI chatbot and knowledge base). Several industry comparisons report a PrestaShop module on the Addons.
Takeaway: the right pick when a team answers by hand and wants AI in support.
7. Tidio (Lyro): accessible, but billed by volume
Tidio combines live chat, automations and the Lyro agent. The Starter plan is listed at $24.17/month for 100 billable conversations; Lyro conversations start at $32.50/month for 50. Lyro relies on FAQ articles written inside Tidio, not on your PDFs. Our Heeya vs Tidio comparison covers the differences.
Takeaway: handy to start, to watch once AI conversation volume grows.
Which PrestaShop Chatbot Fits Your Store
- Support dominated by shipping, returns and documented product questions: Heeya, for a flat fee and no module.
- Large catalogue, many combinations, product advice: Emporiqa or Knowband, which read the catalogue live.
- Lots of "where is my order?": AI SmartTalk or Emporiqa, which sync orders.
- Tight budget, PrestaShop 1.6 or 1.7: Smart IA Chatbot, after a test on your own content.
- A team answering live: Crisp or Tidio, with AI in support.
Many stores combine two tools: a RAG agent to absorb the routine questions and a live chat or helpdesk for the human cases. Facing the same decision on another platform? See our best AI chatbot for Shopify guide.
FAQ: Best PrestaShop Chatbot
What is the best PrestaShop chatbot in 2026?
There is no single winner. For catalogue, stock and order lookups, a catalogue-connected module (Emporiqa, AI SmartTalk, Knowband) fits. For shipping, returns and product questions answered from your terms and FAQ at a flat price, Heeya is built for that need.
Is there a free PrestaShop chatbot module?
Yes, such as "Chatbot par Botnation" on the Addons, but check the last update date and compatibility with your version. An unmaintained free module can become a security or conflict risk.
Do I need a PrestaShop module to install an AI chatbot?
No. A SaaS chatbot like Heeya installs with one script line in your theme, whatever your PrestaShop version. A module only matters if the bot must read your catalogue or orders.
Can an AI chatbot track a PrestaShop order?
Only if it is connected to the shop database, like the Emporiqa, AI SmartTalk or Knowband modules. A script-based RAG agent answers from your content: it can explain how to track a parcel and offer a contact form.
How much does a PrestaShop AI chatbot cost?
From a free module to several hundred euros a month. Expect roughly €80 to €150 one-off plus API usage for a module, €9.90 to €79 a month for AI SmartTalk, €19 or €99 a month for Heeya, or $0.25 per conversation for Emporiqa. Our AI chatbot cost guide breaks down the pricing models.
Is a PrestaShop chatbot GDPR compliant?
It depends on the vendor and your setup. Chatbot conversations are personal data processing under the GDPR: tell visitors, set a retention period and check where messages travel. A module wired to a US API sends the conversation content to that provider. See our GDPR-compliant AI chatbot guide.
Does the chatbot work on a multilingual PrestaShop store?
Modules generally follow the shop language. Heeya covers French and English, with a widget that follows the page language; for other languages, pick a tool that lists them explicitly.
Can a chatbot increase sales on PrestaShop?
It reduces hesitation by answering shipping and returns questions at any hour, which removes a common barrier to purchase. We cannot promise a universal figure: measure questions handled and contacts avoided over 30 days.
Final Verdict
The best PrestaShop chatbot is the one that matches what your customers ask most. If it is about one order or one product's stock, take a module that reads the shop. If it is shipping, returns, payment and product questions already written on your pages, a script-based RAG agent does the job, with no module to maintain and no bill that follows your traffic.
Either way, test on your own content before paying: ask twenty real customer questions and check the answers. That is the only comparison that counts. Our ecommerce chatbot can be tried for 7 days with no card.

Import your terms, FAQ and product pages, paste the script into your theme, and check the answers before you pay anything.
