Claim-Aware Version Review
Map rewritten blocks, compare commercial claims, prioritize verification risks, and let ChatGPT propose exact patches while you retain final approval.
Word Frequency Counter
Count every word in pasted text or a URL. Search and sort the bounded vocabulary table, edit stop words, and export CSV or JSON.
Keyword Density Checker
Measure words, bigrams, and trigrams, track exact phrases, and compare density changes between result A and B.
Bag of Words Analyzer
Inspect vocabulary, bigrams, tracked phrases, and Zipf distribution, then save result A and compare it with result B.
Text Analysis Comparison
Compare two texts or webpages by length, vocabulary, normalized word and bigram frequency, and Zipf diagnostics.
N-gram Analyzer
Explore recurring phrases from unigrams through longer n-grams.
Bag of Words Generator
Build raw term vectors from pasted text or a URL and inspect frequencies, percentages, and vector coverage.
TF-IDF Calculator
Score terms with corpus-aware weights across 2–10 documents for model-ready ranking and filtering.
Text Similarity Calculator
Measure cosine similarity between two texts using BoW or TF-IDF representations and inspect top contribution terms.

How to Calculate Word Frequency
Counts, percentages, per-1,000 rates, tokenization, and a worked example.
GUIDEKeyword Density Formula
Exact phrase calculations, comparison rules, and why density is not a ranking score.
NLP GUIDEBag of Words Model
How frequency tables become document vectors and machine-learning features.
NLP GUIDETF-IDF Formula

NLP GUIDECosine Similarity for Text
Vector overlap, BoW versus TF-IDF weighting, contributions, and limits.
NLP GUIDEWhat Are N-grams?
Unigrams through longer windows, denominator rules, filtering, and practical uses.
WORKFLOW GUIDECompare Texts by Word Frequency
Normalized vocabulary changes without confusing frequency analysis with a character diff.
