String Inspector & Text Forensics Studio
Analyze character metrics, byte sizes, Unicode code points, readability scores, word frequencies, invisible zero-width characters, and crypto hashes in 100% private browser memory.
Character Classification
Whitespace & Layout Anatomy
Lexical Richness & Indices
All string tokenization, unicode decoding, and Web Crypto hashes run entirely within your local browser sandbox. No text or files are uploaded to any server.
Correctly parses 32-bit surrogate pairs (emojis, CJK glyphs, mathematical symbols) and calculates true code point lengths instead of naive UTF-16 code units.
Computes Flesch Reading Ease, Flesch-Kincaid Grade Level, Automated Readability Index (ARI), and Coleman-Liau metrics for content editors and copywriters.
Frequently Asked Questions
What is the difference between Character Count and UTF-8 Byte Size?
ASCII characters (A-Z, 0-9) consume 1 byte each in UTF-8. Non-Latin characters (like Cyrillic, Arabic, Greek) take 2 bytes, East Asian CJK characters take 3 bytes, and emojis take 4 bytes. A 10-character string containing 10 emojis takes 40 bytes.
How does the Zero-Width Character detector work?
It checks every code point against known invisible unicode ranges such as Zero-Width Space (\u200B), Byte Order Mark (\uFEFF), and Non-Breaking Space (\u00A0), allowing you to pinpoint and strip hidden characters that break JSON or code builds.
How is the Flesch Reading Ease score calculated?
The formula calculates 206.835 - 1.015 × (total words / total sentences) - 84.6 × (total syllables / total words). Higher scores (90-100) mean very easy reading, while lower scores (0-30) indicate university or legal complexity.
Can I export the full forensic analysis?
Yes! You can click "Export JSON Report" to download a comprehensive JSON file containing every token, character classification, readability score, and crypto hash, or click "Copy Markdown" for instant pasting.
