Post once, fit everywhere

Every platform counts differently: X weights emoji and links, Bluesky counts graphemes, SMS switches encoding when a single curly quote appears. These tools apply each platform’s actual rules. See social media character limits.

Questions

Why does X say my post is too long?

X counts emoji and CJK characters as two and every link as 23. The Social Media Character Counter applies those rules; the guide Social Media Character Limits and How Each Platform Counts explains them.

How do I split a long post into a thread?

Paste it into the Thread Splitter, which breaks at sentences and numbers each post within the limit.

Why are my YouTube chapters not showing?

YouTube requires the first timestamp at 0:00, at least three chapters in order, and each at least 10 seconds long. The YouTube Chapters Generator checks all four.
