TextAnalyzer Pro FAQ

A1: A text analyzer that runs in your browser. Paste a text and it counts words, characters, sentences and paragraphs, estimates reading and speaking time, scores readability with six formulas and a consensus grade, reads the tone from a word list, lists keywords, phrases and a word cloud, examines the sentence structure (length, passive voice, connectors, adverbs), suggests what to edit, compares two texts side by side and keeps saved analyses with trends. Nothing is uploaded and there is no account.

A2: Nothing. There is no plan, no limit and no feature held back. Like every page on ZeroDataUpload, the tool is supported by advertising.

A3: No. There is no registration and no login. Paste text and read the tabs.

A4: Yes. The cards stack one above the other, the six tabs wrap into two rows, and the charts follow the width of the screen. Paste uses the phone's clipboard where the browser allows it; if the button is blocked, tap in the box and use the keyboard's own paste.

A5: The counts, keywords, phrases, word cloud, sentence lengths, baseline and comparison work for any language written with spaces between words. The readability formulas, the syllable estimate, the tone lexicon, passive voice, transitions, adverbs and the plain-English list are built for English and give meaningless numbers for other languages.

A6: Words are runs of letters and digits in any script, with apostrophes kept inside them (don't is one word). A sentence ends at a full stop, question mark or exclamation mark followed by a space, or at a line break; decimals such as 3.5, initials such as J. K. and common abbreviations such as Dr., e.g. and U.S. do not end one. Paragraphs are separated by an empty line.

A7: Words divided by the reading speed in Settings, 230 words a minute by default, which is an average adult reading on a screen; the slider runs from 100 to 400. Speaking time uses 130 words a minute, the pace of a clear presentation. Under a minute the time shows in seconds.

A8: Unique words are the distinct words ignoring case; lexical diversity is unique words as a share of all words. It falls naturally as a text gets longer, because the, and and of keep coming round, so compare texts of similar length and treat it as a rough guide under a hundred words.

A9: It is the longest run of letters and digits, so a URL, an email address or a word joined by hyphens can win. Hyphenated words are split for the syllable count but kept whole here.

A10: Flesch Reading Ease runs from 0 to 100, higher being easier: 60 to 70 is plain English, 90 and above very easy, under 30 academic. Flesch-Kincaid Grade, Gunning Fog, Coleman-Liau, SMOG and the Automated Readability Index each give a U.S. school grade (12 is the last year of high school, 16 a bachelor's degree). The consensus grade is the average of the five, and the reading level names the audience it suits.

A11: The formulas divide by the number of sentences and words, so a sentence or two produces wild numbers. Ten words and one sentence is the minimum; the scores settle down past a hundred words. SMOG is designed for thirty sentences or more and is marked approximate below that.

A12: They measure different things. Flesch-Kincaid and Automated Readability react to sentence length, Gunning Fog and SMOG to the share of words with three or more syllables, Coleman-Liau to letters per word. A text of short sentences full of long technical words scores low on the first pair and high on the second. When they disagree by more than about three grades, the outlier tells you what is pulling the score.

A13: By a rule, not a dictionary: vowel groups are counted, a silent final e is dropped, and a few common patterns are corrected. It is right for most words and off by one for some (created, science), which is how every automatic readability tool works, and the formulas were calibrated with the same kind of counting. The textbook example, "The Australian platypus is seemingly a hybrid of a mammal and reptilian creature", scores 37.5 here, as published.

A14: No. The scores are fitted to sentence and word length and know nothing about meaning, order or accuracy. They catch the two commonest problems, long sentences and long words, and they let you compare two drafts of the same text. A clear text with long technical terms scores worse than it reads; vague short words score better. Use the consensus grade with the suggestions and the highlighted sentences, not on its own.

A15: Every word is checked against a list of about 220 positive and 230 negative words; a negation in the two words before (not, never, isn't, hardly, without) flips it, and the flipped word is shown as "not good" or "not bad". The score is positive words minus negative words, divided by their total, so it runs from -1 to +1: above +0.3 is very positive, above +0.1 positive, below -0.1 negative, below -0.3 very negative, and anything else neutral.

A16: Because it counts words, not meaning. "The support was great until the product failed" has one positive and one negative word and scores neutral; sarcasm and context escape it entirely. That is why the Tone tab lists the exact words it counted: judge each one, and treat the score as a check on drift rather than a verdict.

A17: The number of positive and negative words with a bar for each, and how many of all the words carried a tone at all. A text where one word in a hundred is on either list is nearly neutral whatever the score says; one where one word in ten is loaded has a strong tone.

A18: Words of three letters or more, ignoring case, after about 230 common function words are removed (the, and, of, is, was, very, also and the rest). The top fifteen are listed with their count and their density, the share of all words. Two-word phrases are consecutive keywords that occur at least twice, which catches terms such as "social media" or "data security".

A19: One to three percent marks a clear topic word. Above three percent a reader notices the repetition, and search engines stopped rewarding density years ago; the density table marks those rows. Under one percent is normal for everything but the main subject.

A20: The forty most frequent keywords are sized by their count and placed from the centre outwards, so the biggest words sit in the middle; the layout is the same each time for the same text. Download PNG saves a 1600 by 800 picture with a solid background in the current theme.

A21: A form of be (is, are, was, were, been, being, get, got) followed, optionally after an adverb, by a word ending in -ed or by one of about ninety irregular past participles (done, made, written, taken). It is a heuristic: it misses passives without an auxiliary and flags a few adjectives (was tired). The sentences it marked are listed so you can check them.

A22: Show highlights draws the text with sentences of 25 to 34 words underlined in amber and sentences of 35 or more in red; hover one for its word count. The difficulty line plots words per sentence from the first sentence to the last, with dashed lines at 25 and 35, so a heavy stretch in the middle of a text stands out.

A23: From thresholds an editor would use: an average sentence over 25 words, more than a fifth of the sentences passive, -ly adverbs over five percent of the words, too few or too many connectors, low vocabulary diversity past a hundred words, paragraphs over 150 words, a consensus grade over 12, a strongly negative tone, and words with a plainer alternative. Each one says what it measured, and a text in the comfortable range on every count gets a single green note.

A24: Rules of thumb for five kinds of text: a blog post of about 1,500 words at grade 8, a news article of 800 at grade 10, marketing copy of 500 at grade 7, technical documentation of 2,000 at grade 14 and an academic paper of 5,000 at grade 16. The table says how your length and grade differ; within a quarter of the length and a grade and a half counts as about right.

A25: About sixty words and phrases with a shorter everyday twin: utilize and use, prior to and before, in order to and to, facilitate and help, a number of and some. The Structure tab lists the ones found in the text with a count.

A26: It keeps the current numbers (words, sentences, average sentence length, diversity, Flesch ease, consensus grade, tone, passive share) in this browser. From then on the Baseline Comparison card shows each measure as baseline, now and change, so you can see what an edit did. Clear baseline removes it.

A27: Put a text in each box (Use the main text copies the Text box into A; Open a text file reads a file; Swap exchanges them). The table shows thirteen measures for both with the difference, green on the side that reads easier or more varied where that makes sense, plus the share of distinct words the two texts have in common and the keywords they share. Both boxes are remembered in this browser.

A28: A snapshot: the date, the first line as a title, the counts, the consensus grade, the Flesch ease, the tone and the first 20,000 characters of the text. Up to 50 are kept, newest first. The Saved window lists them with Load (puts the text back in the box) and Delete, offers Download all as JSON, and from two saves on shows trends: the number saved, average words, grade and tone, and bars of the words and grade of the last twenty.

A29: Open a text file reads a .txt, .md, .csv, .json, .html or other text file up to 2 MB into the box, and dropping such a file on the box does the same. Export offers JSON with every number, keyword, phrase and sentence length, CSV of the metrics and keywords, a text or Markdown report with the suggestions, a copy of the report to the clipboard, and Print, which lays every tab out on one page so the browser can save it as a PDF.

A30: The Text box (up to 100,000 characters), the two compare boxes, the open tab, the saved analyses, the baseline and the reading speed are kept in this browser's storage. Clear empties the box, the Delete buttons remove saved analyses, and Clear data in Settings removes everything the tool stored, and nothing else on the site.

A31: Nowhere. The analysis runs in your browser and nothing is sent to a server. Like every page on the site, the tool page shows ads through Google AdSense and uses Google Analytics; the Privacy Policy and Cookie Policy explain what those collect. Your text is never part of it.

A32: Reading the clipboard needs a secure page and a permission, and some browsers and most phones refuse it to a web page. Click in the box and press Ctrl+V (Cmd+V on a Mac) instead.

A33: The text has fewer than ten words or no sentence yet. Add text, or check that the box holds words and not only numbers or symbols.

A34: They are drawn when their tab is opened and need text: the cloud needs at least one keyword, the line at least two sentences. If the tab was opened before the text was pasted, switch tabs once and back.

A35: A line break ends a sentence, so a list of short lines counts each line, and hard-wrapped text pasted from a PDF counts each printed line. Paste the text through TextTransform's Join lines first, or remove the breaks in the box.
