Threads now lets you add 10,000 character text attachments to posts

Meta is adding a new feature to let you add a bunch of extra text to Threads posts — no screenshots of text blocks required. Starting today, Meta is rolling out a tool that lets you attach up to 10,000 characters of text to Threads posts, giving you a way to build upon the 500-character text limit already available when making a post. It’s kind of a Threads-y take on X’s Articles feature.

You can add a text attachment to a post by tapping on a new rounded rectangle icon with some lines on it. After tapping that, a word editor opens up where you can type away, and you can format your text with bold, italics, underlines, and strikethroughs.

On your feed, a text attachment appears as a small block below your main post. When you tap that block, it will expand to show the full attachment for you to read. If you include a link in your main Threads post, that link will also be shown in the expanded text attachment, meaning the tool could be a useful way to share a preview of an article or a blog post and then direct readers to the full thing.
