Features and specs

What each product offers, as listed by its team.

OptiDress.fr 4 features
https://open-gpt.app/ 5 features
  • Virtual Fitting Room
    Shoppers enter their height, weight and body shape, no photo, ever. Their 3D digital twin is generated in seconds, and they see the garment worn on their own body. Where most solutions lose the shoppers who won't photograph themselves mid-purchase, OptiDress keeps them.
  • Native size recommendation
    For every product, the size to order is displayed along with a fit description, calculated from the shopper's body data and the garment's real measurements, cut, dimensions, fabric. Not a size chart sitting next to a render: the same profile drives both the visual and the sizing.
  • Avatar saved for 30 days
    Returning shoppers find their digital twin waiting and try garments on straight away. Fashion purchases rarely happen in a single visit — without persistence, the shopper starts over every time and eventually gives up.
  • Self-serve on Shopify, assisted setup elsewhere
    On Shopify, OptiDress installs from the App Store as a native app and you set it up yourself. On WooCommerce it ships as a WordPress plugin, and on any other store as a universal script — there, the OptiDress team handles installation and configuration. No theme rebuild and no new product photography: the widget appears on your product pages in your brand colours, prepared from your existing visuals and your garments' real data.
  • Accessible AI Chat Interface
    Provides a user-friendly web-based interface for interacting with GPT-based AI models without needing to set up API access or coding knowledge.
  • No Installation Required
    Being a web application, it can be used directly from a browser without downloading or installing any software.
  • Potentially Free or Low-Cost Access
    Many GPT wrapper sites like this offer free tiers or lower-cost access compared to official API pricing, making AI chat more accessible to casual users.
  • Quick Setup
    Users can typically start chatting almost immediately after visiting the site, with minimal account creation or configuration steps.
  • Cross-Platform Compatibility
    Since it runs in a browser, it can be accessed from various devices including desktops, tablets, and smartphones without platform-specific versions.

Possible disadvantages

  • Uncertain Reliability
    Third-party GPT wrapper websites often depend on underlying API access that can be unstable, rate-limited, or discontinued without notice, affecting consistent availability.
  • Data Privacy Concerns
    Using an unofficial third-party service to process conversations raises questions about how user data and conversation history are stored, used, or shared.
  • Limited Transparency
    It may be unclear which underlying AI model version is being used, how up-to-date it is, or what modifications have been made to the base model's behavior.
  • Potential Hidden Costs or Ads
    Free-to-use AI wrapper sites often monetize through ads, premium upsells, or data collection, which may not be clearly disclosed to users upfront.
  • Lack of Official Support
    Unlike official AI platforms, unofficial wrapper sites may lack dedicated customer support, regular updates, or accountability if issues arise.

Questions & Answers

As answered by people managing OptiDress.fr and https://open-gpt.app/.

Why should a person choose your product over its competitors?

OptiDress.fr's answer

Three reasons, in order of what they change for a store.

No photo means no lost shoppers. A share of visitors will not photograph themselves at the point of purchase, and every photo-based tool loses them silently.

Fit and appearance in one product. Sizing isn't a second tool to buy and connect it runs on the same profile, per product, with a fit description.

Nothing to build. The OptiDress team handles installation and configuration in under 24 hours, across Shopify, WooCommerce, Magento, PrestaShop, BigCommerce, Wix, Squarespace, Webflow, Shopware, Salesforce and custom builds. No theme rebuild, no new product photography, no development work.

Pricing scales with monthly store traffic rather than render counts, with no commitment which keeps it accessible to independent brands rather than enterprise budgets.

What's the story behind your product?

OptiDress.fr's answer

OptiDress was founded in 2026 in Paris by Arthur Renard and Raphaël Zafran.

The starting point was a gap in how virtual try-on had been built. Tools either showed garments on generic models, useful for presentation, useless for fit, or generated an image from a photo the shopper uploaded, which excludes everyone unwilling to photograph themselves and still can't say which size to order. Sizing was sold as a separate product, by separate vendors.

The choice was to build from declared body data instead of images: one profile that drives both what the shopper sees and the size they should order, with no photo at any stage. And to make it accessible to independent brands, not just retailers who can absorb an enterprise contract.

What makes your product unique?

OptiDress.fr's answer

OptiDress is the only virtual fitting room where neither the avatar nor the try-on requires a photo. Shoppers enter their height, weight, body shape and optional measurements, a 3D digital twin is generated from that data alone. Because the system holds real body data rather than an image, the same profile also powers a per-product size recommendation with a fit description, calculated against each garment's real measurements, cut and fabric. Most tools answer how a garment looks; a photo carries no measurements, so they can't tell shoppers which size to order. The avatar is saved on the store for 30 days, so returning shoppers don't start over.

How would you describe the primary audience of your product?

OptiDress.fr's answer

Independent fashion brands and e-commerce retailers selling apparel online, primarily on Shopify. Typically direct-to-consumer brands where the founder or e-commerce lead makes the decision, companies feeling the cost of size-related returns and abandoned carts, but without the budget or team for an enterprise deployment. Currently focused on Western Europe, the UK and the US.

Which are the primary technologies used for building your product?

OptiDress.fr's answer

Web-based SaaS. Front-end widget embedded on merchant product pages, back-end services handling avatar generation and size computation. AI-powered garment rendering. Integrations through native apps and plugins across major e-commerce platforms, plus API access for custom builds. EU-hosted.

Who are some of the biggest customers of your product?

OptiDress.fr's answer

OptiDress currently works with a selected group of independent fashion brands in Europe. Customer names are not published at this stage.
