How it works
Get your result in 3 steps
Step 1: Type or paste your text
Write your caption, bio or post straight into the tool – or paste it in with copy & paste. Characters, words and hashtags count up live as you type. Everything runs in your browser; nothing is stored.
Step 2: Check the limits per platform
See at a glance whether your text fits the character limits for Instagram (caption & bio), TikTok, X, LinkedIn, Facebook and YouTube – with a progress bar, a heads-up just before the limit and a clear alert when you go over.
Step 3: Optimize the truncation point
The preview shows you exactly where each platform cuts your text off with “… more”. Move your strongest line in front of that point – because that’s the part that decides whether your audience keeps reading or keeps scrolling.

FAQ
Frequently asked questions
Character counter: count characters & words online – free
This character counter counts your text live – characters, words and hashtags – right in your browser, free and without sign-up. You type or paste your text in, and the count updates in real time. Spaces, line breaks, emojis and hashtags are all included, so when you count characters or count words you see exactly the numbers your editor, form or platform will show later.
Unlike a plain “count characters online” tool, this counter checks your text against the character limits of the most important social media platforms at the same time. Here’s how people typically use it:
- Check an Instagram caption against the 2,200-character limit and pull the hook in front of the ~125-character cutoff
- Fit an Instagram or TikTok bio into a tight character limit (150 or 80 characters)
- Double-check tweets against the 280-character limit on X (Twitter)
- Trim LinkedIn and Facebook posts for readability before the “… more”
What does a character counter actually count?
A character counter captures every single character in your text – letters, numbers, punctuation, spaces and line breaks. Emojis like 🚀 count as one character, and hashtags are counted including the # sign. There’s one quirk on X: every link counts as a flat 23 characters there, no matter how long the URL really is – this tool accounts for that too. For stronger posts, pair it with the free tools in the overview – from caption and hook helpers to the social media audit and the comment generator. More reach beyond the first line is explained in the guide to social media comment management. Once your text is ready, replient.ai makes sure no comment goes unanswered: automatic replies in your brand voice, around the clock.
