Free Thread Splitter
Split a long paragraph into a Twitter thread or Threads posts instantly with this free thread splitter. Paste your draft, choose X for a 280-character limit or Threads for a 500-character limit, and copy the resulting posts. The X option uses ThreadMaster's shared splitter and weighted character counter, so links and many non-Latin characters affect the budget differently from ordinary letters. Turn on numbering to add a position marker to every copied post, with space reserved for the marker. Blank lines keep separate ideas apart. Review the cards before publishing, especially when your draft includes long words, emoji sequences, or links. This tool organizes text you already have; it does not write new material. For a new first line, try the hook generator, then check the flow in the thread preview. Everything updates in your browser without an account.

Frequently asked questions
How do I split a Twitter thread?
Paste your text and select X. The shared splitter divides your draft, and the tool fits oversized pieces within the selected budget.
Can I split posts for Threads?
Yes. Select Threads to use a 500-character budget based on Unicode code points rather than X weighting.
Does numbering count toward the limit?
Yes. The tool reserves room for a marker such as (1/5), and copied posts include that marker.
Are links kept?
Yes. Links stay in the output. The X counter assigns each detected URL a weight of 23 characters.
