How does a split text into tweets work?

It packs your text into chunks of at most 280 weighted characters (URLs count 23, non-ASCII characters count 2), splitting on sentence and then word boundaries.

Split Text Into Tweets

What is Split text into tweets?

X Thread Splitter — Split long text into tweet-ready posts: paste up to 20,000 characters and get numbered posts with markers, broken cleanly on sentence and word boundaries.

This tool greedily packs your text into posts of at most the per-post limit, breaking first on sentence boundaries and then on word boundaries — never mid-word. The numbering marker’s length is reserved before splitting, then every post is re-validated after the marker is added. It uses a conservative weighted count (URLs count 23, non-ASCII characters count 2); long unbreakable tokens such as URLs are kept whole. No AI or generation is involved — it is pure deterministic splitting.

Good to know

Splitting is purely rule-based and deterministic — no AI or content generation is involved.
The weighted count is a conservative approximation (URLs count 23, non-ASCII characters count 2); the 280 budget is the documented default, not a live check of X’s current rules.
A single unbreakable token longer than the budget (extremely rare; URLs are kept whole at 23) is hard-split rather than dropped — the summary tells you if this happened.
