Meta AI is currently offering a limited experience on WhatsApp. But that might change soon. In WhatsApp beta for iOS 26.20.10.72, the option to upload documents directly to Meta AI is currently being tested in the in-chat attachment menu. This feature, available on other AI-powered assistants, lets you upload the file you want Meta's AI assistant to analyze. Previously, users needed to take screenshots or send images to achieve a similar result.
As a beta feature, though, it is currently only available to some testers. And there is currently no guarantee that the feature will be released as an official functionality in the future.
