Word counter and social media character counter
Type or paste your text. Words and characters update as you go, and every platform below turns red the moment your post is too long for it.
Your text is saved in this browser only, so it's still here if you close the tab.

Fits the limit, but does it sound like you?
A post can be the right length and still read like it was written by AI. Paste it into the free AI detector to see which phrases give it away, or read how to write LinkedIn and social posts without the AI voice. For short posts, the lesson on sentence rhythm helps most.
