JustDone is an AI writing and study app with a humanizer at its core, and it suits students who would use several of its 35+ tools in one subscription. The humanizer has an Academic style and a built-in AI detector check.

A JustDone AI humanizer review is partly a review of the bundle around it, since every plan includes all 35+ tools. Whether it's good value depends on how many of those tools you'd open in a typical week.

What is JustDone?

JustDone is a subscription platform from GM Appdev Limited, a company based in Limassol, Cyprus. Its tools cover writing, research and study, and the AI humanizer is listed next to an AI detector, a plagiarism checker and a paraphraser on the main menu. JustDone says students from more than 3,000 universities and institutions use it.

JustDone names four groups it built the humanizer for: students, non-native English writers, content creators and marketers, and professionals writing reports, proposals and emails. Students are the main audience, and most of the bundle is built around coursework.

The humanizer rewrites AI-generated text so it sounds natural while keeping the original meaning. You paste text, load a sample or upload a file, choose a style and click Humanize. JustDone says it changes sentence rhythm, tone and predictability, beyond swapping words for synonyms.

How JustDone's humanize, detect and refine loop works

JustDone builds its humanizer around three steps: humanize the draft, check it with the detector, then refine the flagged parts in your own words. The steps run in one place, so you don't copy text between sites.

Three styles

You pick a style before you humanize. Academic is formal and well structured, Formal & Professional is polished for an audience, and Neutral & Conversational is easy to read.

You can switch styles during a session, so one document can use a different style in each section. A lab report could keep Academic for the method and results and use Neutral & Conversational for a plain-language summary.

Sentence-level detection

JustDone's AI detector gives an AI-likelihood score broken down by sentence. After you humanize, the detector shows which sentences still sound machine-written, and you can rework only those.

In practice, start with the sentences the detector marks most strongly and rewrite them yourself, with a detail or example only you would add. Then run the check again, since every edit changes the score of the sentences around it.

JustDone calls the score "a signal, not a verdict", and says it's less reliable on short texts. That's a fair description of any detector. If your own writing is ever flagged, our student and researcher playbook for appealing a false AI-detection flag covers what to do next.

Refining in your own words

The last step is yours. JustDone suggests reading the result aloud, editing anything that doesn't sound like you and adding a specific example or detail of your own. It also suggests starting from your own outline, so the ideas in the draft are yours before any AI is involved.

Those habits matter more than any setting. A rewrite that keeps your argument and adds your own examples is closer to your work, and easier to defend if anyone asks how you wrote it.

The 35+ tools in a JustDone subscription

Every JustDone plan includes the full set of 35+ tools, so the subscription price buys the whole bundle. JustDone groups the main ones into writing, learning and research, and productivity.

Writing checks

The writing group has the humanizer, the AI detector, a grammar checker, a plagiarism checker and a paraphraser. JustDone separates the jobs clearly. Rewriting recreates sentences from scratch, paraphrasing puts existing text into new words with smaller changes, and humanizing keeps the text largely intact while adjusting rhythm, structure and word choice. The plagiarism checker compares your text with billions of sources and gives a sentence-level similarity report, and the paraphraser lets you choose a tone and the strength of the rewrite.

A similarity report takes some practice to read, since quotes and references can count as matches. Our guide to reading a Turnitin similarity report explains which matches matter and which don't. For a quick grammar pass without a subscription, our free grammar checker works in the browser.

Research and study tools

The learning and research group has an AI Researcher, a Topic Explainer and an AI chatbot. Productivity tools include a summarizer, a citations tool, a note organizer and an AI study planner, and the menus also list a fact checker and a quiz generator.

If you only need one of these occasionally, a free tool may cover it. Our free AI summarizer condenses articles and chapters, and our citation generator builds references in the main academic styles.

Chrome extension

JustDone's Chrome extension brings its tools into other sites, so you can work on text where you write it. It's included in every plan with the rest of the bundle. That helps if you write in an online editor and want to check or rewrite a paragraph without switching tabs.

JustDone pricing and the US$2 seven-day access

JustDone costs US$19.99 a month, or US$9.99 a month on the annual plan, and every plan includes all 35+ tools. There's also a seven-day access for US$2. JustDone showed these prices on 4 October 2026:

PlanPriceWhat happens next
7-day AccessUS$2Renews at US$29.99 a month unless you cancel at least 24 hours before the seven days end
Unlimited MonthlyUS$19.99 a monthRenews each month until you cancel
Unlimited AnnualUS$9.99 a monthAnnual plan, the lowest monthly price

JustDone says there are no extra costs or fees beyond the plan price, and all prices are in US dollars. It accepts credit and debit cards, PayPal and Apple Pay.

Renewal timing

For one essay due within the week, the seven-day access covers the whole job for US$2. Cancel once you've finished, and well before the 24-hour cutoff.

The seven-day access renews at US$29.99 a month, which is more than the Unlimited Monthly plan at US$19.99. If you decide to keep JustDone after the trial week, switching to a regular plan before day seven costs less.

To stop the renewal, cancel at least 24 hours before the seven days end, in your account settings or by emailing support. JustDone's subscription terms set out the trial, renewal, cancellation and refund rules, and it suggests keeping a screenshot of them.

Monthly or annual

For a single project, the seven-day access or one month of Unlimited Monthly is enough. For regular use across a semester or a year, the annual plan at US$9.99 a month costs half as much per month as monthly billing.

JustDone's plans have unlimited words, so the choice depends on how long you'll use it. That makes the annual plan good value for students who write every week. It suits a full academic year of coursework better than a string of monthly renewals.

A Humanizer for Papers With Citations to Keep

ProofreaderPro.ai's humanizer is designed to lower AI scores while APA, MLA, Chicago, IEEE and Turabian citations stay in format, with frozen terms and tracked-changes export on Academic Plus. Plans start at US$19 a month.

Who gets the most from JustDone

JustDone suits students who would use the humanizer alongside the detector, the plagiarism checker and the study tools. It suits academic writers with cited papers less well, since its styles don't include citation or terminology settings.

What JustDone says about responsible use

JustDone's humanizer page has a section on academic integrity with three commitments, which it calls clarity, honesty about limits and transparency about AI. It says a lower detection score isn't the same as original authorship, and that presenting a chatbot's words as your own can be a form of plagiarism, even after rewording.

That's useful framing for any humanizer. The tool can make a draft clearer, and the ideas and the disclosure stay your responsibility.

Students who use several tools

If you'd check plagiarism, summarize readings and plan your study time in the same week, the bundle saves you several separate subscriptions. The humanizer and detector loop also helps you learn which of your sentences sound generic.

JustDone asks students to follow their institution's rules and cite AI help where those rules require it. Our guidance on AI use and disclosure covers what to say and where to say it.

Non-native English writers

JustDone suggests its humanizer for turning machine-translated phrasing into natural English. For a draft written in your second language, the Neutral & Conversational style can make stiff sentences easier to follow.

Your own meaning still comes first, so compare each rewrite with what you intended to say. Our guide to native-level English for ESL researchers covers what to check in a paper written in a second language.

Researchers with cited papers

A journal paper or thesis has to keep its reference style, its defined terms and every figure unchanged. JustDone's styles adjust register, and its citations tool is a separate step, so check every in-text citation after a rewrite.

JustDone AI Humanizer vs. ProofreaderPro Humanizer

JustDone is a study bundle with a general-purpose humanizer, while ProofreaderPro.ai's humanizer is made for academic papers with citations and technical terms. JustDone's annual plan costs less per month, and ProofreaderPro.ai keeps citation formats in place.

For a student who wants a humanizer, detector, plagiarism checker and study tools in one place, JustDone covers more ground for the price. Its annual plan at US$9.99 a month is cheaper per month than ProofreaderPro.ai's Academic plan.

For a thesis chapter or a journal paper, ProofreaderPro.ai fits better. Academic Plus keeps citations in their original style, freezes the technical terms you choose and records every change in a file your supervisor can open in Word. Our piece on tracked changes as proof of process explains why that record helps when someone asks how a text was revised.

JustDone AI Humanizer Alternatives

The right alternative depends on which part of JustDone you'd use most. Some students want a lighter study suite, some want a free humanizer, and researchers need citation handling. For a broader view, see our AI humanizer ranking for academic writing in 2026.
