Thread Splitter
Split long text into Twitter/X thread posts under 280 characters — smart sentence breaks.
1 post in thread
About this tool
Long-form ideas often exceed a single post limit. This splitter breaks your text into thread-sized chunks at sentence and word boundaries for X/Twitter and similar platforms.
How to use the Thread Splitter
- 1
Paste your long-form text or article summary.
- 2
Set max characters per post (280 for X/Twitter).
- 3
Copy each post in order to publish as a thread.
Thread structure
Post 1 should hook readers — the split preserves your opening paragraph when possible. Number posts (1/, 2/) in the text if your audience expects it.
End the final post with a CTA: follow, subscribe, or link to the full article.
Pro tips
- Preview each chunk character count before posting.
- Bluesky allows 300 characters — adjust the limit accordingly.
