Meta has begun testing a new feature on Threads that allows users to share long-form text within a single post, the company confirmed on Thursday.

According to TechCrunch, the tool enables users to attach a block of text rather than creating a sequence of separate posts when expressing extended ideas or commentary. The feature appears under the name “text attachment” and was first observed on iOS by app researcher Radu Oncescu, who also published a screenshot of the function.

According to the in-app description, the feature lets users attach extended text and use formatting options to present news snippets, book excerpts, and other material requiring additional space.

The addition may assist Threads in retaining writers and creators who typically publish longer content on blogs or platforms such as Substack. It also eliminates the need for indirect methods, such as sharing screenshots from a phone’s Notes app, to bypass character limits.

Threads user Robert P. Nickson shared an example post, displaying the text attachment as a grey box embedded within the post. Viewers can tap the box to read and scroll through the full content.

The feature bears similarity to the “Articles” tool on X (formerly Twitter), which permits users to publish long-form content. X restricts the feature to Premium subscribers, while Threads currently offers its version to all users, although this may change.

At present, Threads supports only text within this feature, whereas X also allows images and video. As Meta continues testing, support for multimedia attachments may follow.

Meta confirmed plans to expand the feature’s availability in future updates.

The long-form post feature joins a broader set of additions Threads has introduced over the past year, including direct messages, fediverse integration, custom feeds, and AI tools.

Threads recently surpassed 400 million monthly active users, two years after launch. X remains ahead, with over 600 million monthly users, according to past statements by former CEO Linda Yaccarino.
