Thread splitter
Paste long text and automatically split it into a numbered tweet thread at natural break points.
about the thread splitter
X threads are the most powerful format on the platform for organic reach — they hold attention longer than single tweets, get reshared as units, and drive more profile visits than any other content type. But writing a thread from scratch is a different skill than writing a single tweet. This tool solves the opposite problem: you've already written something long, and you need to break it into a thread without losing the flow.
The splitter finds natural break points — paragraph ends, sentence boundaries, logical transitions — and divides your text into numbered tweets that each fit within X's 280-character limit. It's smarter than a raw character-count chop, which would cut mid-sentence or mid-thought.
Paste your essay, article section, or talking points, and get a numbered thread back. Copy it into PostAI's Twitter scheduler to queue the whole thread to publish as a unit at your chosen time — each tweet fires in the correct reply sequence automatically.
frequently asked questions
What is the best way to split a long post into a Twitter thread?
Split at natural paragraph or sentence breaks so each tweet contains one complete thought. This thread splitter finds those break points automatically, keeping every tweet under 280 characters without cutting mid-sentence.
How many tweets should a Twitter thread be?
3-15 tweets is the sweet spot for most content — long enough to deliver real value, short enough to read without commitment. The algorithm rewards threads that earn high completion rates, so shorter and tighter usually outperforms long and padded.
Can I schedule a split Twitter thread?
Yes. Paste your thread into PostAI's Twitter scheduler after splitting. PostAI publishes each tweet in the correct sequence with proper reply chaining, at any future time you choose.
want to schedule and post, not just format?
PostAI schedules to 11 platforms, includes AI content generation, and starts at $9/mo.
