PrestaShop AI & purchase decision

Our best PrestaShop AI modules to help customers choose

Five modules to remove the doubt — not to persuade the customer.

Your customer does not leave because it was too expensive — they leave because they were not sure. And that doubt has a price: either they do not buy, or they buy and send it back.

The problem

Sound familiar?

A doubt about size

They do not know which size. So they do not buy — or they buy, and you get it back.

A product you cannot picture

The photo shows a model. The customer wants to see it on themselves — and cannot.

A search that does not answer

They have an image but not the words. Your search only understands words.

Reviews nobody reads

Nobody reads two hundred reviews. So the question stays — and becomes a doubt.

The shortlist

Our selection, ranked

Every module below is built, maintained and supported by our team. The ranking reflects what we would install first on a client store.

  1. AI Size & Fit Advisor

    The doubt that costs most

    Size is the leading cause of returns. The only lever that both sells more and gets less back.

    Recommend the right size from each shopper's measurements and morphology — where the static size guide stops.

  2. Virtual try-on. More spectacular than the size advisor — but it answers a different question.

    AI virtual try-on widget on your product pages, powered by Google Vertex AI Try-On. Photo upload or camera, 100% server-side, GDPR consent, SynthID watermark,…

  3. The customer has a photo but not the vocabulary. Useful in fashion and decor — noise on technical catalogues.

    Your customers search by photo: they drop in an image and the module surfaces the visually closest products in your catalog. With Shop the…

  4. AI Review Pros/Cons Synthesizer

    The answer before the question

    Pros and cons drawn from real reviews. More credible than your copy, precisely because it names the drawbacks.

    The module reads hundreds of reviews and automatically displays the key Pros and Cons, in the language of each product page.

  5. A first-time visitor and a regular customer do not need the same arguments.

    Show the right content to the right visitor. Segment by profile, behavior, cart and context, then serve tailored blocks in any theme zone —…

The customer does not leave over price — they leave over doubt

You assume they left because it was too expensive. Most of the time they left because they were not sure. Not sure about the size. Not sure it would suit them. Not sure it looks like the photo.

And that doubt has a measurable price: either they do not buy — or they buy and send it back. Both cost you.

AI does not sell — it removes the doubt

That is the only standard that counts. An AI module that persuades the customer is a module that generates returns. An AI module that helps them choose correctly lifts conversion and cuts returns at the same time.

That is why the size advisor comes first on this page and not the virtual try-on: it is less spectacular and it moves both metrics at once.

The only question before buying

Which doubt is your customer actually holding back when they click “Buy”? Your return reasons answer that. Install the module that removes that doubt — not the one that looks best.

Buying guide

How to choose

Read your return reasons first

They tell you exactly which doubt your customer could not overcome. “Too small” = size advisor. “Not like the photo” = try-on or a better image. “Not what I was looking for” = visual search. Your returns are your shopping list — and they cost nothing to read.

The standard that judges every AI module

A module that persuades creates a sale and a return: a loss. A module that helps the customer choose correctly lifts conversion and cuts returns at once. Track both metrics after every installation — never one without the other.

Why the size advisor comes before try-on

Try-on is more spectacular. It answers “does it suit me?” The size advisor answers “does it fit me?” — and that is the question whose wrong answer creates a return. In fashion, size is the leading cause of returns by a wide margin.

When to install none of this

If you sell technical spare parts to professionals who know their reference by heart, none of these modules solves a problem you have. Your doubt is in compatibility, not appearance. Closing this page is a perfectly good decision.

What you gain

The doubt that costs the most

Size is the leading cause of returns. The only lever that both sells more and gets less back.

Seeing it on yourself

Virtual try-on shows what no photo shows. The customer sees it on themselves — not on a model.

Searching without words

The customer has a photo but not the words. Visual search finds the product from the image.

The answer before the question

The AI review synthesis answers the question before it becomes a doubt — pros and cons.

Convince, do not persuade

A module that persuades generates returns. A module that helps you choose correctly generates customers.

The right message per profile

Content personalised by segment: the B2B buyer and the first-time visitor do not see the same thing.

Implementation

From install to results

  1. Read your return reasons

    They tell you exactly which doubt your customer could not overcome. Your shopping list, free.

  2. The size advisor first

    It moves conversion AND returns. No other module in this selection does both.

  3. Convince, do not persuade

    A module that persuades creates a sale and a return. That is, a loss.

  4. Track both metrics

    Conversion and return rate, always together. If the second rises, the module is persuading.

  5. Install nothing if your catalogue does not need it

    If your customers know their reference by heart, none of these modules solves a problem you have.

“We installed a recommendation module that was persuasive. Too persuasive: conversion rose 9%, returns rose 14%. We had been selling losses.”

Frequently asked questions

Which module first?

The one your return reasons name. “Too small” = size advisor. “Not like the photo” = try-on or a better image. “Not what I was looking for” = visual search. Your returns tell you exactly which module to install — and which would be noise.

Why the size advisor before virtual try-on?

Because it moves both metrics at once. Try-on is more spectacular, but it answers “does it suit me?” — the size advisor answers “does it fit me?”, and that is the question whose wrong answer creates a return. In fashion, size is the leading cause of returns by a wide margin.

Can an AI module increase returns?

Yes, and it is the standard by which an AI module should be judged. A module that persuades the customer creates a sale and a return — that is, a loss. After installing, track your return rate: if it rises, the module is persuading. If it falls, it is genuinely helping.

When is visual search genuinely useful?

When your customers arrive with an image rather than a word. In fashion, home decor and spare parts that is common: the customer sees what they want but cannot name it. On a technical catalogue where everyone knows the reference, it is noise.

What does the AI review synthesis bring?

It answers the questions the customer would have had to ask — before they ask them. Nobody reads two hundred reviews; a synthesis with pros and cons does get read. And it is more credible than your product copy precisely because it names the drawbacks too.

What if my catalogue is not visual?

Yes, and it should be said: if you sell technical spare parts to professionals who know their reference by heart, none of these modules solves a problem you have. Your doubt is elsewhere — in compatibility, not in appearance. Install none of them.

Why personalise content by segment?

Because a first-time visitor and a regular customer do not need the same message. One needs reassuring, the other does not. Personalisation is not a gadget: it stops feeding arguments to a customer who has already decided.

Which metric proves it is working?

Your return rate, alongside your conversion rate — never one without the other. An AI module that lifts conversion and lifts returns just as much has gained you nothing. It has simply moved the loss.
