Real Word-Pattern Analysis, With Transparent Reasoning

This checks your text against curated word lists for formality markers (contractions, casual phrasing) and sentiment (positive/negative vocabulary), then shows you exactly which words drove the result -- genuine lexical analysis with full transparency, not an opaque black-box score.

An Important, Honest Limitation: No Sarcasm Detection

Word-list-based analysis fundamentally can't distinguish sincere positive language from sarcastic use of the same words -- "great, another Monday" would likely register as positive tone despite the obvious sarcasm. This is a real limitation of any keyword-based sentiment approach, not specific to this tool, and worth keeping in mind when interpreting results.

By checking your text against curated word lists associated with each register -- contractions, casual interjections, and informal phrasing signal casual tone, while longer formal connectives and more structured phrasing signal formal tone. The balance between matches determines the overall lean.

Similarly, through curated positive and negative word lists -- counting how many words from each list appear in your text and comparing the relative balance, a straightforward but genuinely real lexical analysis approach.

This approach can't detect sarcasm, context-dependent meaning, or nuanced tone that doesn't rely on obviously charged vocabulary -- 'great, another Monday' would likely register as positive despite being sarcastic, a genuine and important limitation of any keyword-based sentiment method.

Transparency about which words actually drove the classification lets you judge for yourself whether the result makes sense for your specific text, rather than just trusting an opaque score with no visibility into the reasoning.

Confirming an email or message lands with the formality level you intended, checking that marketing copy reads as positive as intended, or reviewing whether written communication might come across more negatively than you meant.
