Provei.AI
: How to use it, features, and the business problems it solves

What is Provei.AI?

Provei.AI is a visual AI platform that adds "see, choose and create" experiences to e-commerce product pages. It is developed and operated by Reverbs Ai Tecnologias LTDA in São Paulo, Brazil, and serves mainly Brazilian e-commerce businesses.

When shopping online, customers have to imagine how a garment would look on them, whether a sofa suits their room, and which size to pick. To close this gap between the catalog image and the purchase decision, Provei.AI organises its features into three families.

• Visualize: fashion virtual try-on, and visualising furniture and home decor, flooring and wall coverings in a room
• Sizing: size chart, size recommendation and size comparison
• Studio: Provei Studio, which creates catalog and campaign images from product references

"Fashion Virtual Try-On": try clothes on with your own photo

When a shopper uploads their own photo, Provei.AI generates an image of them wearing the garment configured by the store. The experience stays inside the product page, so the shopper can add the item to the cart without leaving for another site.

The company positions the try-on result not as an exact reproduction of fabric texture, colour or drape, but as a way to understand the garment's style, composition and visual presence. For fit and measurements, it is designed to be used together with the sizing features described below.

Results depend on the photo's quality, framing and body visibility, so shoppers are guided on choosing a suitable photo when uploading. It is aimed at women's and men's apparel, streetwear, multi-brand stores and similar retailers.

Check furniture, flooring and walls with a photo of the room

Beyond fashion, it supports home furnishings and interior finishes.

• Furniture and Home Decor Visualizer: the shopper picks a product and sends a photo of their room, and gets back an image with the furniture or decor placed in that space, to judge style, composition and presence before buying
• Flooring and Wall Coverings Visualizer: applies the flooring or wall coverings configured by the store to a photo of the room, with the flow designed to continue to support, a quote or a purchase

The company states clearly that these images should not be treated as a technical design or an exact measurement. Whether furniture will physically fit, or whether a covering can be installed, should be confirmed with the room and product measurements.

Size chart, size recommendation and size comparison

Size selection is supported by combining three features.

The Size Chart presents the product's official measurements in a structured way and can also be used on its own. Size Recommendation suggests the most compatible size from the information the shopper enters and the measurement data configured by the store.

Size Comparison lets shoppers compare the recommended size with a tighter or looser option on the same model, side by side. In the example screen, under the recommendation "Choose size M", images of sizes M and G (equivalent to L) are shown next to each other.

"Provei Studio" for creating product images

Provei Studio lets brands and e-commerce teams create catalog and campaign images from product reference images. As of October 2026, it supports fashion products.

Creation proceeds in four steps: (1) choose the objective and format (product only, model with product, social visual, ad composition, etc.), (2) choose the product, (3) set the model, pose, background and style, and (4) review and generate. Resolution can be standard, 2K or 4K, and higher resolutions use more credits per attempt.

Generated images are meant to be compared and reviewed before publication; Studio does not publish images automatically. The company also asks that people review product fidelity and usage rights for reference images before use.

How to use it

1. Book a demo Request a demo through the contact form on the official site, by email (contato@provei.ai) or via WhatsApp. Share your store's domain, e-commerce platform, product category, approximate catalog size, country of operation and what you want to do (visualize products, guide sizing or create content).
2. Scope a small pilot The company recommends starting with a pilot focused on one problem and one category. During the demo, you define the target categories, required data, integration, the limits of the experience and the review steps.
3. Integrate it into your store Platforms such as Shopify and VTEX follow the official step-by-step guides; for other stores, the team guides script installation. You can also adjust the look, such as button colours and placement and your own watermark on generated images.
4. Expand while measuring results Check usage on the metrics dashboard and add categories or features as needed.

Supported e-commerce platforms

The official website provides installation guides for these 16 platforms:

Shopify / WooCommerce / VTEX / Nuvemshop / Magento / Tray / Squarespace / Wix / PrestaShop / Yampi / Loja Integrada / Bagy / Magazord / Dooca / Wbuy / WAKE

However, the company notes that having a guide does not mean every feature is automatically enabled on any store. What is available depends on the theme, product category and catalog references, so confirm before implementation.

Pricing

Plans are monthly and differ by the number of AI image generations per month. On the pricing page, entering your monthly visits shows a recommended plan (checked October 2026; whether prices include tax is not stated).

Published case studies

The official website publishes three case studies with their periods and comparison baselines. Read them bearing in mind that the company itself says the results "are not guarantees" for other customers, and that comparing users of an experience with the store-wide average "does not establish causality by itself".

The homepage also cites 100K+ try-ons completed, +34% conversion and −23% returns, but the comparison conditions for these figures are not given.

Data handling

Because the service handles photos showing shoppers' faces and bodies, here is what the official FAQ and privacy information say.

• The company says it follows Brazil's data protection law (LGPD)
• Shopper photos are processed in memory, discarded after the session and not stored permanently, according to the company
• It says it uses AES-256 encryption
• The demo screens on the official site use a synthetic model with no personal data
• As of October 2026, no third-party certification such as ISO or SOC 2 has been published

Pros and cons

Pros

• Try-on, room visualisation, sizing guidance and product image creation can be adopted together under one contract
• Covers not only apparel but also furniture, home decor, flooring and wall coverings
• A careful design that keeps try-on and size recommendation separate and does not treat images as measurements
• Case studies are published with periods, metrics and comparison baselines
• Starts at $49 a month with an unconditional 7-day money-back guarantee

Cons

• The official website is in English and Portuguese; Japanese is not supported
• No track record in the Japanese market and no guides for major Japanese cart systems (such as Makeshop or futureshop)
• As of October 2026, Provei Studio supports only fashion products
• You can estimate costs on the pricing page, but signing up goes through a contact request
• Generated images are probabilistic and need human review before publication

Reviews and reputation

Besides the Lojas Torra, CasaLar and Approve case studies, the official website shows logos of several customers, including furniture stores and apparel brands. As of October 2026, we could not find Japanese-language reviews or Japanese customer cases.

The published case studies are announced by the operator. As the company itself recommends, the surest way to see whether it fits your business is a pilot focused on one category, using your own products and traffic.

How it differs from other fashion and e-commerce image AI

If you want to produce product images efficiently, FASHN, Photoroom and Claid.ai are candidates. Provei.AI suits stores that want not only to create images but to build experiences where shoppers try items on and compare sizes right on the product page.

FAQ

Q. Can Provei.AI be used on Japanese e-commerce sites? The 16 platforms with official installation guides include Shopify, WooCommerce, Magento, Wix and Squarespace, which are also used in Japan. However, the official website is in English and Portuguese, and terms for Japan are not described, so contact the company before implementation.

Q. Can I try it for free? There is no free plan. Every plan has an unconditional 7-day money-back guarantee with a full refund if you are not satisfied.

Q. Does the virtual try-on tell me whether the size fits? No. The try-on shows the visual impression and does not indicate fit. Sizes are guided by the size chart, size recommendation and size comparison features.

Q. What happens if I run out of generations? You can buy additional credits that never expire, and you can set up automatic top-ups so you don't run out.

Q. Are shoppers' photos stored? According to the official FAQ, photos are processed in memory, discarded after the session and not stored permanently. The company says it follows Brazil's LGPD and uses AES-256 encryption.

Q. Can furniture or flooring images tell me whether something will fit in the room? No. The company states that visualisations do not replace technical designs or measurements. Confirm physical fit with the room and product dimensions.
