Microsoft adds custom Copilot apps inside SharePoint sites
Reviewed by Helen Jones
Microsoft released SharePoint Copilot Apps. The feature lets developers create custom experiences that run inside SharePoint and pull from site content. The announcement came from the Microsoft 365 developer blog on 23 June. No licensing details or rollout timeline were included. The move extends Copilot beyond chat into structured SharePoint surfaces.
Until now Copilot mostly answered questions in a side pane. Admins could contain the blast radius by keeping sensitive sites out of search or limiting who had licences. SharePoint Copilot Apps change that equation by letting the AI operate directly inside the sites themselves. The practical result is that every permission mistake, abandoned page, and external sharing link becomes visible through an interface people will actually open. Sites that were merely untidy now carry real exposure risk.
Analysis
Audit the 20 busiest SharePoint sites for broken inheritance and external links before any Copilot App pilot starts. Skip the feature on anything that fails that check.
