About CharCap
CharCap is a character counter for writing that has to fit somewhere. Type or paste a draft and it counts characters, words, sentences and paragraphs as you go, along with an estimated reading time. Next to the editor, a grid shows how the same text measures up against more than 20 platform and field limits at once, including an X post (280), an Instagram caption (2,200), a LinkedIn post (3,000), a TikTok caption, YouTube titles and descriptions, a single SMS message, SEO page titles and meta descriptions, and email subject lines. Each limit has a progress bar that changes color as you approach it and again when you go over, so you can see at a glance where a post would be cut off.
Some platforms hide text well before the hard limit, behind a "See more" link. CharCap marks those recommended lengths with a tick on the bar, which helps you keep the important part of a message in view. Tabs narrow the grid to social, SEO, messaging or email fields when you only care about one kind of destination. It is most useful when one piece of text is headed for several places, such as an announcement, a short bio or a page's meta tags. Counting happens in your browser as you type. Your text is not sent to a server, and there is no account to create.
