Is this X character counter free?

Yes. There is no login and no upload: it runs entirely in your browser, and nothing you type or attach leaves your device.

What happens if an X post goes over the limit?

X crops or refuses it. The counter marks the exact tail that would be lost, so you can cut the right words instead of guessing.

Where these numbers come from: our sourced X spec page, every figure carrying its citation and the date we last checked it.

We built these because our own agents count against exactly these limits before they publish. Let them write the post too.
