Overview
- Meta confirmed it is testing a feature that lets users attach long-form text to a post, after app researcher Radu Oncescu surfaced it and users like Roberto Nickson and Justin Mixon shared examples.
- The attached text appears as a gray box preview that opens into a scrollable full-screen view on mobile and a dedicated window on the web.
- Current styling supports italics, bold and underline, with no embedded media or hyperlinks in this test phase.
- The test can be viewed by all users and appears to be available outside any paid tier, with Meta saying it plans to expand access but without a timeline.
- Screenshots indicate these posts do not federate to ActivityPub services, raising interoperability questions as Threads positions the feature against X’s paid Articles.
