Delve, leverage, foster, robust, seamless, tapestry. Paste your draft and every one of them comes back marked, with the reason it stands out and a replacement you can apply in one click. Your vocabulary range, your repeated words and the ones you lean on hardest are measured underneath.
Stock lexicon is the loud problem. The quiet one is range: a draft can be clean of every flagged word and still lean on the same six nouns from the first paragraph to the last. These figures update with the box above.
The stock lexicon is not a random list of banned words. It falls into three groups, and knowing which group a word belongs to tells you what to replace it with.
None of these words are obscure. Delve, foster and robust have been in English for centuries. What marks them is the rate: a model reaches for them far more readily than a person writing about the same subject, so a cluster of them in one paragraph is unusual in a way the individual words are not.
Robust, meticulous, crucial and invaluable are verdicts. They tell the reader how to feel about a thing without describing the thing. Generated prose leans on them because a verdict is always available and a specific detail is not.
Ecosystem, landscape, tapestry and paradigm are borrowed nouns that name a mood rather than an object. Sometimes one of them is the right word. Usually it is standing in for a noun the sentence never gets around to naming.
Formal register learned from a textbook overlaps with the register models produce, and detectors cannot tell the two apart. Peer-reviewed work found 61% of TOEFL essays by non-native English speakers falsely flagged across seven commercial detectors, while essays by native speakers came through nearly clean. Who gets flagged, and why it happens covers the study in full.
14 rules cover these 24 entries plus their inflections. Leverages, leveraged and leveraging all belong to the row marked "leverage", and the adverbs (robustly, seamlessly, meticulously) belong to theirs. Every row was produced by running the phrase in the first column through the registry the box at the top uses, so what is printed here is what the tool will offer you.

No account, no upload, no word cap. The scan runs the moment the text lands, because the word list and the rules are already in this page.
Every finding shows the word as you typed it, how many times it appears, and one sentence on why that word reads as machine-written.
Single-word rules carry their own inflection table, so "Delving into" comes back as "Digging into" rather than "dig into". Replace one instance, or every instance of that word at once.
Range, repetition and the words you lean on hardest are measured underneath. A draft can be clean of stock lexicon and still say "important" nine times.
Find-and-replace on a word list breaks tense. The single-word rules each carry their own inflection table, so "leveraged" comes back past tense and "delving" comes back as a participle. The phrase rules offer one plain-English phrase, so read the sentence back after a phrase swap.
The applier cleans the seam either way: no doubled space, no space stranded in front of a comma, and the capital restored when the edit lands at the start of a sentence. Where a rule swallows a following preposition — "delving into" — the replacement carries it, so you do not end up with two.
The ones this page marks: delve, leverage, foster, utilize, robust, seamless, meticulous, holistic, tapestry, synergy, paradigm, ecosystem, landscape, myriad, game-changer, and the rating adjectives — crucial, pivotal, paramount, vital, invaluable. The registry covers 14 lexicon rules in total, some of them phrases rather than single words, and the full list is printed further down this page.
One instance in a long essay proves nothing. Three in four paragraphs, alongside "leverage" and "robust", is a pattern, and pattern is what a statistical checker measures. The count matters more than any single word, which is why this tool reports counts rather than a verdict.
No. "Ecosystem" is the correct word in an ecology paper and "landscape" is correct in a geography one. The tool marks the word and gives you the reason; the judgement about whether it is carrying weight in your sentence is yours. Replacing a word that was doing real work makes the writing worse, not less detectable.
Vocabulary is one input among several. Sentence rhythm, structural habits like the "not X, but Y" pivot, and hedging all feed the same class of classifier, and no tool can tell you what a specific detector will output on a given day. What this page can tell you is exactly which words in your draft belong to the stock lexicon, and what to put in their place.
Unique words divided by total words. It falls as a text gets longer, because common words repeat no matter how varied the writing is, so there is no threshold that means "good" across documents of different lengths. It is useful for comparing two drafts of the same piece, and misleading for anything else.
By this tool, no. It names words and gives you the choice about each one. By commercial detectors, often yes. Formal register learned from textbooks overlaps heavily with the register models produce, and that overlap is a large part of why false positives fall unevenly.
