WeChat 4.1.15 Desktop Update Adds In-Call Invitations and AI Search for Documents

Tencent released WeChat version 4.1.15 for Windows and macOS with unified feature updates across desktop platforms. The new version allows users to invite additional participants during one-on-one voice or video calls and introduces AI querying for shared files and Official Account articles. This update streamlines collaboration by letting users expand private calls without hanging up to start a group call, while bringing AI-assisted reading tools directly into desktop workflows. It reflects Tencent's strategy of embedding AI search and processing natively into WeChat's rich ecosystem of articles and documents. The Windows and Mac releases were published simultaneously with identical change logs. Notably, certain features tested in earlier beta builds—such as converting outgoing voice messages to text and detached browsing windows—were omitted from this public release.
