What is Character Counter?
A real-time character counting tool for documents with character limits such as cover letters, resumes, and essays. It displays characters with/without spaces, byte count, word count, sentence count, paragraph count, and estimated reading time at a glance. It also includes a built-in Korean spell checker so you can catch typos and grammar errors before submitting job application documents. Content is auto-saved to your browser local storage so it persists even if you close the window.
How Do Bytes and Character Count Differ?
Character count treats each character as 1, while byte count measures the encoding size. Korean characters are 2 bytes each, while English letters, numbers, and basic symbols are 1 byte each.
1 Korean character = 2 bytes · 1 English letter or number = 1 byte
For example, 2 Korean characters plus 5 English letters make 7 characters total, but in bytes it becomes 4 + 5 = 9 bytes. Some companies like Samsung and SK limit text by bytes, so it is important to check which unit applies.
Spell Check Engine
Based on an algorithm similar to Pusan National University AI Lab, it checks text according to Korean standard spelling rules. Errors are categorized into three color-coded types.
Typo Corrections
Shown in red. Detects basic spelling mistakes and suggests the correct form.
Spacing Corrections
Shown in purple. Fixes spacing and punctuation errors, including words that should be joined or separated.
Style Improvements
Shown in blue. Suggests improvements for unnatural grammar and phrasing such as translation-influenced expressions or double-passive constructions.
Line Break Handling
Windows treats line breaks as 2 bytes while Mac and Linux use 1 byte. This tool uses the same CRLF handling as major Korean job platforms like Naver and Saramin so character counts match. However minor differences may occur depending on your OS and browser so it is recommended to leave some margin.
