Understanding Text Analysis
Hidden Characters
Zero-width spaces, non-breaking spaces, and other invisible characters can cause bugs in code, break copy-paste operations, or indicate text manipulation. This tool detects and counts them all.
AI Writing Signals
This tool detects common patterns in AI-generated text like excessive transition phrases, uniform sentence lengths, and hedging language. Note: these are heuristic indicators, not definitive detection.
Flesch Reading Ease
Scores range from 0-100. Higher scores indicate easier reading: 90-100 (5th grade), 60-70 (8th-9th grade), 30-50 (college), 0-30 (professional/academic).
100% Client-Side
All analysis runs entirely in your browser using JavaScript. Your text is never sent to any server. You can verify this by disconnecting from the internet - the tool will still work perfectly.
