AI-powered character counter with platform optimizer, content analyzer, and writing optimizer. Count characters, analyze text complexity, detect writing issues, and optimize content for every social platform.
| Char | Count | Frequency |

Type or paste any text into the textarea. This could be a tweet, Instagram caption, SMS message, or any text with character limits.
See your character count with and without spaces, word count, line count, and byte size update instantly. Check platform-specific limits highlighted below.
Use the AI tabs to optimize for platforms, analyze character distribution, and get writing suggestions to improve your content quality.
Twitter limits tweets to 280 characters. Our tool shows exactly how many characters you have left, including with or without spaces, so your tweet posts without truncation.
Instagram allows 2,200 characters for captions. Craft the perfect caption knowing exactly how much space you have for hashtags, mentions, and your message.
Standard SMS messages are limited to 160 characters. Know instantly if your message will be split into multiple texts, which can affect costs for business messaging.
Many online forms, job applications, and government portals have strict character limits. Verify your responses fit before submitting to avoid errors.
Character counts update as you type — no refresh, no buttons, instant feedback for efficient editing.
Detect language scripts, measure text entropy, analyze character distribution, and get AI-powered writing suggestions in real-time.
All processing happens in your browser. Your text is never sent to any server — 100% client-side and secure.
Works with any language, including emoji, special characters, and non-Latin scripts like Arabic, Chinese, and Hindi.
Characters with spaces count every letter, number, punctuation mark, and space character. Characters without spaces exclude only space characters. For example, "Hello World" has 11 characters with spaces but 10 without. Some platforms count spaces, others do not — our tool shows both so you can choose.
The AI Platform Optimizer shows real-time progress bars for all major social media platforms including Twitter/X (280), Instagram (2,200), LinkedIn (3,000), Facebook (63,206), TikTok (2,200), YouTube (5,000 description / 100 title), Meta Description (160), and SMS (160/320). Each bar shows remaining characters and changes color from green to red as you approach or exceed the limit.
The AI Content Analyzer detects your text's language scripts (English, Numbers, Special characters, CJK, Emoji), displays a visual pie chart of character distribution, shows a frequency table of most common characters, and calculates Shannon Entropy to measure text complexity. Higher entropy indicates more random or complex text.
The AI Writing Optimizer detects excessive punctuation (!!!, ???), ALL CAPS abuse (more than 3 consecutive uppercase letters), repeated characters (aaa, !!!), suggests optimal title lengths based on content, and provides actionable improvement suggestions to make your writing more professional and readable.
Shannon Entropy measures the unpredictability or complexity of text. A simple word like "aaaa" has very low entropy (predictable), while a mixed text with varied characters has higher entropy. It helps assess text quality — very low entropy may indicate repetitive content, while very high entropy might suggest random or encrypted text.
Emojis are typically counted as 2 characters by most platforms (Twitter, Instagram) because they use surrogate pairs in Unicode. Our tool counts them based on JavaScript's string length, which matches how most social media platforms handle emoji counting. A single emoji like 😀 counts as 2 characters.
