Count characters
for X posts.
Stay inside 280 characters, or switch on X Premium for the long form. Tune hashtags and copy a ready post without uploading anything.

Built around the X limit.
X is the tightest common limit. Use the counter while you draft, move hashtags to the end, or strip links so the post still fits.
- Default focus is X with a 280-character ceiling.
- Optional X Premium mode raises the limit to 25,000.
- Still generate Instagram, LinkedIn, and other variants from the same draft.

Questions, answered.
Is my caption uploaded?
No. Counting, trimming, and export all happen in your browser. Turtao never receives the text.
How are characters counted?
The tool counts Unicode grapheme clusters (what people usually mean by “characters”), including emoji. Platform rules can still differ slightly, so treat limits as a practical guide.
Does shortening use AI?
No. When a caption is too long, the tool drops trailing hashtags first, then trims at a sentence or word boundary. Your wording is not rewritten by a model.
Can I schedule these captions?
Copy them into Turtao on your Mac to schedule and publish across accounts without pasting into each app by hand.
