String Analyzer
Analyze text metrics, character and word counts, readability scores, and estimated reading times online.
Run tool
The String Analyzer inspects text passages to calculate structural metrics, readability scores, and estimated speech and reading durations. Paste or type any string into the input area to inspect total character length alongside UTF-8 byte size. The tool identifies individual words through boundary matching and tracks unique terms by comparing words in lowercase. It also separates content into lines, paragraphs, and sentences based on standard punctuation and newline breaks. Beyond structural volume, the analyzer counts ASCII letters, digits, whitespace characters, and punctuation marks, while measuring uppercase and lowercase letter distribution. It computes average word length and average sentence length rounded to one decimal place. For longer passages containing more than five words and at least one sentence, the tool evaluates syllable structures across ASCII words to calculate readability scores and grade levels. Speech and reading estimates provide quick reference times in whole minutes based on standard paces.
Instructions
- Paste or type your text content into the Text field.
- Click the analyze button to process your text.
- Review the detailed character, word, sentence, and paragraph counts.
- Check the readability metrics, letter distribution, and estimated reading and speaking durations in the summary panel.
Examples
- Analyze a draft blog post: Paste an article draft to count words, check paragraph breaks, and see estimated reading time.
- Check sentence structure in a speech: Paste speech notes to check average words per sentence and estimated speaking duration in minutes.
FAQ
How are reading and speaking times calculated?
Reading duration is estimated at 200 words per minute and speaking duration at 130 words per minute, rounded to whole minutes with a minimum of one minute for nonempty text.
What text is required to generate a readability score?
The analyzer calculates readability scores and grade levels for text containing more than five words and at least one sentence ending in standard punctuation.
How does the tool count unique words?
The analyzer identifies words using boundary matching and compares all words in lowercase to find the count of distinct terms.
What happens if the text input is left empty?
Submitting an empty text input returns zero for all numeric counts, zero time estimates, and an unavailable status for readability metrics.
