X (Twitter) Thread Builder
Write a thread one tweet at a time. Each tweet is checked against the 280-character limit, and the whole thread is formatted and ready to copy.

What gets copied
The thread copies as numbered tweets separated by blank lines, so you can paste them into X one at a time — or into your favorite scheduler.
1/3 Your first tweet here... 2/3 Your second tweet continues the story... 3/3 Your closing tweet with the takeaway.
Frequently asked questions
What is the character limit for each tweet in a thread?
Each individual tweet in a thread is capped at 280 characters for free accounts, just like a standalone post. The builder checks every tweet against that limit as you write, so you find out before you post instead of after.
How many tweets can a thread have?
There's no hard limit on the number of tweets in a thread, but practical threads run 5–20 tweets. Longer threads lose readers fast, so the builder nudges you to keep each tweet focused.
Do numbered tweets help threads perform better?
Many top thread writers use a numbered format (1/7, 2/7, and so on) because it signals a series and invites readers to keep going. The builder can number your tweets automatically, or you can leave them unnumbered.
Can I copy the whole thread at once?
The builder lets you copy each tweet individually and also copy the full thread in one go, so you can paste the whole thing into X in order without jumping back and forth.
