Writing tools
A free alternative to the paid writing assistants, built for essays, reports and assignments. No account, no word limit, no trial that expires — and your work never leaves your browser.
6 free tools · no sign-up · nothing uploaded
Catch spelling, grammar, punctuation and wordiness as you type.
Tighten wordy writing with every edit shown and reversible.
Flesch, Gunning Fog, SMOG and three more, with sentence rhythm.
APA, MLA, Harvard, Chicago, IEEE and Vancouver references.
Compare two documents and see exactly which passages overlap.
See whether your writing reads formal, confident or critical.
Why these are free, and what the catch is
The paid writing assistants charge because they run trained language models on their own servers, and that costs real money per document. These tools do something different: they ship a rule engine to your browser and run it there. Serving a rule engine costs the same whether ten people use it or ten thousand, which is why there is nothing to charge for and no word limit to enforce.
The honest trade-off is coverage. A rule-based checker finds mistakes that follow recognisable patterns — misspellings, punctuation, agreement, wordy phrasing, passive voice. It cannot parse a sentence or understand what you meant, so it will miss errors that need context and it will occasionally flag something correct. Every tool here says which of those it is doing, and every suggestion can be ignored.
What each tool actually does
Grammar & Spelling Checker: underlines mistakes in place as you type, explains each one, and fixes the unambiguous ones in a click. Spelling includes the inflected forms, so “recieved” is caught as well as “recieve”.
Paraphrasing Tool: four rewriting modes, with every edit listed and reversible. It substitutes wording — “due to the fact that” becomes “because” — rather than restating ideas, and it says so.
Citation Generator: APA 7, MLA 9, Harvard, Chicago, IEEE and Vancouver, each implemented against its own published rules. Italics survive the copy, so references paste into Word already formatted.
Readability Checker: six published formulas plus the sentence rhythm none of them report.
Text Similarity Checker: compares two documents you supply and highlights every overlapping passage.
Tone Checker: estimates register, certainty and outlook from word choice, and tells you when it does not have enough signal to be confident.
On plagiarism, and what we will not pretend to do
A real plagiarism checker compares your work against a crawled index of the web and a database of submitted student papers. Building and running that index costs a great deal of money, which is why the services that offer it charge for it. Any free tool claiming to scan “billions of web pages” is either not doing that or is funded by something it is not telling you about.
So this site does not offer one. What it offers instead is the part that genuinely works in a browser: a similarity checker that compares your draft against sources you already have, so you can confirm that what you borrowed is quoted and cited properly. Paired with the citation generator, that covers what most students actually need before they submit.
For the same reason there is no “AI humaniser” here. Tools that promise to make written work undetectable are selling something they cannot deliver, and the thing they are selling is a way to misrepresent authorship. Improving writing so it reads clearly is a different job, and that is what these tools do.
Frequently asked questions
Do I need an account?
No. There is no sign-up, no email capture and no trial. Open a tool and use it.
Is there a word limit?
No. The checks run on your own device, so the only limit is your computer's memory. A full dissertation chapter is fine.
Is my writing uploaded or stored?
No. These tools have no upload endpoint — the analysis happens in JavaScript in the page. You can verify it by opening your browser's network tab while you type. The citation generator saves your reference list in your browser's local storage on that device only.
How does this compare to Grammarly or QuillBot?
It catches less than they do, and it costs nothing rather than a monthly fee. They run trained language models that understand sentence structure; these run pattern rules. For spelling, punctuation, wordiness, citations and readability the gap is small. For subtle grammar that depends on meaning, the gap is real, and it is better to know that than to be told otherwise.
Do the tools work offline?
Yes. Once the page has loaded, its code is cached and everything keeps working with no connection.
Can I use these for coursework?
Checking your own writing for spelling, grammar, clarity and references is ordinary proofreading and is accepted everywhere. What is not acceptable is submitting work whose ideas or wording are not yours, whatever tool produced it. Nothing here changes that, and the paraphraser says so on its own page.
