Free Thread Preview
Preview a Twitter thread before you publish by pasting your draft into this free thread preview tool. Choose X or Threads to split the text using the corresponding post budget, then read the resulting cards in order. Each card shows a placeholder avatar, your name and handle, the post text, and its position in the thread. The X option shares ThreadMaster's splitter and weighted character counting logic; the Threads option uses a five-hundred-character budget. This public preview is an approximation of an X-style thread, including when you select Threads. It does not reproduce every platform detail, image attachment, or account setting. ThreadMaster's in-app X preview is pixel-accurate and belongs to the full writing workflow. Use this lightweight version to spot abrupt transitions, isolated sentences, and an opening post that needs work. Edit your text and the cards update immediately, without signing in or publishing anything.
