FAQ
How does the auto-split work?
The tool splits at word boundaries before the 280 character limit, accounting for the thread numbering characters. Use --- to force a split point.
What numbering format works best?
1/N is the most common format on X. It's short and universally understood. (1/N) is more visible. No numbering works for very short threads.
What's the ideal thread length?
5-10 tweets is the sweet spot for engagement. Enough to tell a story but not so long that readers drop off.
