Length checks and previews for the words you publish — captions, subject lines, and copy.
Length, spam-word scan, and an inbox preview for Gmail & Outlook.
Limits for Instagram, X, LinkedIn & TikTok, checked together.
Count words, characters, sentences, and reading time as you type.
Every publishing surface truncates text at a different point, and the cut-off is almost never where you'd guess. Gmail on mobile clips a subject line around 33 characters; Instagram hides everything after ~125 in the feed; X's limit is the hard cap itself. These tools show you where your copy gets clipped on each platform at once.
They also flag the things that quietly cost you engagement — spam-trigger words in a subject line, a caption's first line burning its hook after the "more" fold, hashtag counts past the point of diminishing returns.
Check headline & description limits for Google, Meta, LinkedIn & X ads at once.
