Social Caption Length Checker
Check caption length across major social platforms and spot truncation risk before posting.
Avoid caption surprises at publish time
Different social platforms tolerate very different caption lengths, and many hide long copy behind a truncation point even when the full post is allowed. This checker lets you paste once and see where the same caption is comfortable, risky, or too long.
Use it when adapting a campaign post across channels. A caption that works on LinkedIn may need a tighter hook for Instagram or X, while a TikTok caption may need fewer hashtags and a faster setup.
Private browser-only drafting
The checker runs in the browser only. Draft posts and campaign copy are not uploaded.
