Pro tip: paste a real post. The counter follows the rules of the platform you picked, so the number changes even when the text does not.

Why preview before you post?

Every network folds a post at a different point and measures its length by a different rule. The tool applies each platform’s own rules, so what you see here is what your audience sees in the feed.

Same post, different maths

These are the numbers the tool applies. Each one traces back to a documented source and carries a confidence level.
