Check one draft against every major social platform limit at the same time instead of opening each app to find out where it fits. As you type, this tool shows your character count next to the cap for X posts, Instagram captions, TikTok captions, LinkedIn posts, Facebook posts, YouTube descriptions, Threads and Bluesky, and marks each platform green when you are within its limit or red when you are over. That makes it easy to write once and know exactly which networks will accept the text as is and which need trimming. Word and line counts are shown too. Everything is computed locally in your browser, so your unpublished copy stays private. Draft a caption, glance at the grid, and post to the right platforms with confidence.
It counts your text against X, Instagram, TikTok, LinkedIn, Facebook, YouTube, Threads and Bluesky limits in one view.

Yes, it flags each platform as within limit or over so you can spot the tightest constraint immediately.
