Free online writing tools
Word counters, readability scores, grammar checkers, text transformers, and writing utilities.
Eight text tools, none of which call a language model or a server — every one is a dictionary, a rule set or a Unicode mapping running inside this tab. Grammar Checker matches against a built-in table of 85 habitual misspellings (teh, recieve, seperate, definately, occurence) and ten deterministic rules covering double spaces, repeated words, sentence capitalisation, over-long sentences, passive constructions, missing introductory commas, weak filler words, contractions and missing end punctuation, each of which you can switch off if it does not suit your register; every fix is a suggestion you accept, not generated prose. Paraphrasing Tool works from the opposite direction: a 71-entry plain-English substitution map that turns utilize into use, commence into begin, approximately into about, remuneration into pay and ameliorate into improve, so a draft loses its padding without changing its meaning. Writing Style Analyzer scores how mechanical a passage reads by measuring variance in sentence length and the frequency of connective words such as however, moreover, furthermore and it is worth noting; a low-variance, transition-heavy paragraph scores high, and the accompanying fix list tells you to vary rhythm, use contractions, add asides and cut the connectives. It is a heuristic about style, not a verdict about authorship. Headline Analyzer weighs a title against separate word lists for power words, emotional words and common filler, reports the balance between them, checks length, identifies what kind of headline you have written, and puts two candidates side by side so choosing between them is measured rather than argued. Language Detector compares character trigrams in your text against stored profiles for fifteen languages — English, Spanish, French, German, Portuguese, Italian, Dutch, Russian, Japanese, Chinese, Korean, Arabic, Turkish, Polish and Swedish — and reports the script, region and language family alongside the match. Glitch Text Generator stacks Unicode combining marks from the U+0300 range above, below and through your letters at six intensities, from a single whisper mark up to an apocalypse setting that piles on dozens. Aesthetic Text Generator remaps letters into fullwidth, upside-down and other code-point ranges by arithmetic on the character code rather than by drawing images. Writing Prompt Generator deals prompts across fantasy, sci-fi, horror, romance, mystery and thriller, each arriving with a character, a setting and a twist already attached, which is the part that turns a premise into something you can actually start writing.

How to choose the right tool
Decide whether you want the text judged, cleaned or transformed. To judge it, Writing Style Analyzer answers whether your rhythm has flattened into one sentence length repeated, and Headline Analyzer answers whether a title is carrying any weight — use its comparison view rather than scoring one candidate alone, because the absolute number matters far less than which of two options wins. To clean it, start with Grammar Checker for the misspellings a spellchecker set to the wrong locale keeps waving through, then run Paraphrasing Tool over any paragraph that reads like a consultancy deck; the substitution map is deliberately blunt, so read the result rather than accepting it wholesale. To transform it, Glitch Text Generator and Aesthetic Text Generator both emit copy-pasteable Unicode instead of images, which is why the output survives a bio field but breaks search and screen readers. Language Detector is the outlier: point it at text somebody sent you rather than at your own, to settle which dictionary, locale or translation route the rest of your work should use. Writing Prompt Generator is for the blank page.
Frequently asked questions
Is the grammar checker powered by AI?
No. It is a lookup table plus rule matching, and it never leaves your browser. The spelling half compares your words against a fixed list of commonly mistyped English words and offers the correction. The style half applies fixed regular-expression rules for passive constructions, repeated words, double spaces, over-long sentences and missing end punctuation, and you can switch individual rules off. That makes it fast, private and offline, but it also means it will not understand context, will not catch a correctly spelled wrong word, and will not rewrite a sentence for you. Treat it as a fast first pass before a human read, not as a replacement for one.
Can the Writing Style Analyzer prove text was written by a machine?
It cannot, and no tool honestly can. What it measures is stylistic uniformity: how much sentence lengths vary across a passage, and how densely connective phrases such as however, furthermore and it is important to note appear. Text that is edited into a level cadence scores the same way whether a person or a program produced it, so careful human writing is routinely flagged. Use the score as an editing prompt — if it is high, your sentences probably all run to the same length — rather than as evidence about who wrote something.
Does the paraphrasing tool change what my sentence means?
It can, which is why you should read every swap. The tool applies a fixed substitution map of 71 inflated words and their plain equivalents, with no understanding of context. Most pairs are safe in business prose: utilize to use, endeavour to try, sufficient to enough. Some are not. Significant becomes big, which loses a statistical meaning entirely, and approximately becomes about, which is fine in a sentence and wrong in a specification. It is a de-jargoning pass for a first draft, not a rewriting engine, and it will neither restructure a sentence nor repair the grammar around a replaced word.
What does the headline analyzer actually score?
Four things it can count, and nothing it cannot. It checks how many of your words appear on its power-word list (proven, ultimate, instant, hidden), how many appear on its emotional list (shocking, breathtaking, devastating), how many are common filler, and how that balance sits against the total length. It also classifies the headline type and flags a title long enough to be truncated in a search result. What it cannot know is your audience, your subject or whether the claim is true, so a title that scores well can still be wrong for the piece. Lean on the two-candidate comparison, which is the honest use of a word-list score.
How accurate is trigram language detection on short text?
Poorly on a few words, reliably from roughly a sentence upward. The method counts three-character sequences in your text and compares them to stored profiles for fifteen languages, so it needs enough characters for the distribution to stabilise. Closely related pairs are the weak spot: Spanish against Portuguese, or Dutch against German, share enough trigram overlap to swap places on a short sample. Non-Latin scripts are the easy case, because Cyrillic, Hangul, Arabic and kana ranges are unambiguous on their own. A one-word input will produce a guess; do not rely on it.
Will glitch and aesthetic text work everywhere I paste it?
It is genuine Unicode, not an image, so it survives copy and paste into most bios, captions and chat clients. Three caveats. Combining marks stack upward past the line box, so some layouts clip them and some platforms strip them as abuse. Fullwidth and mathematical alphanumeric letters are separate code points from ordinary letters, which means search, autocomplete and sorting will not match them. Screen readers read many of these substitutions character by character or skip them, so avoid the styled forms for anything a reader needs to actually understand.
