About this tool
This free word counter lets you select your target platform first — LinkedIn, Twitter/X, Instagram, YouTube and more — then shows you exactly how close or over you are in real time. The built-in AI rewriter can trim, tighten or rephrase your content to fit any platform's ideal length, preserving your voice throughout. Everything runs in your browser. Your text is never stored.
