Wix links Wix Harmony to Microsoft 365 Copilot Chat, using OpenAI Apps SDK

has announced a new integration that connects its Wix Harmony website creation platform with Microsoft 365 Copilot Chat. The move is designed to bring website building into the Microsoft ecosystem, allowing users to work on Wix Harmony sites from within Copilot Chat rather than switching between tools.

The company said the linkage is being implemented through the OpenAI Apps SDK, a set of developer tools that helps applications connect to OpenAI’s capabilities. In practical terms, the integration is intended to let prompts inside Microsoft 365 Copilot Chat support actions on Wix Harmony websites, such as creating and managing site content.

For Wix, the product bet is about meeting customers where they already work and lowering friction in the site creation process. Wix Harmony is the company’s platform for generating and iterating web pages, and Wix’s rationale for the partnership is to make those capabilities easier to access from a common business interface like Microsoft’s chat-based assistant.

Financial details were not included in the brief market report, and the company did not provide further specifics about launch timing beyond the announcement itself, nor did it disclose pricing changes or any contractual terms. The post also did not clarify whether the integration is available broadly to all Microsoft 365 Copilot Chat users or only to certain customer segments.

The Microsoft angle is notable because Copilot Chat is positioned as a front end for work across documents, productivity apps, and business workflows. By embedding third-party functionality through developer tooling, Microsoft can expand the range of tasks users can perform from within Copilot, while software partners gain access to Microsoft’s large enterprise footprint.

In the broader software industry, these kinds of integrations are becoming a key competitive battleground. Website builders and content platforms increasingly compete on how quickly users can go from idea to deployed site, and “AI-in-chat” is a natural extension of that effort. Wix’s approach suggests it wants its website creation platform to behave like a guided workflow that can be triggered through conversation, not just through a graphical editor.

Still, several questions remain unanswered. The market report did not describe the boundaries of what Copilot Chat can do on behalf of Wix Harmony, such as whether users can perform full end-to-end site editing, domain and publishing steps, or template selection from chat alone. It also did not state whether there are limitations around languages, website types, or account permissions, all of which can materially affect how usable such assistants are for real projects.
