Justdone Plagiarism Checker
AI-powered plagiarism detection with instant reports and rewrite assistance
Updated August 11, 2026
Justdone Plagiarism Checker Overview
JustDone includes plagiarism checking in a larger AI writing workspace with detection, paraphrasing, citations, grammar, and research tools. Users can upload common document formats, inspect matching passages and sources, and revise flagged sections in the same workspace.
It is aimed at personal writing support rather than institutional case review. Similarity and AI results still need human judgment, especially for academic work.

Pros
Compared with |
Why this product may fit better |
|---|---|
| Quetext | JustDone includes more than 35 tools for research, rewriting, citations and checking. Quetext has a more focused originality workflow, while JustDone can cover more parts of an assignment in one account. |
| Grammarly | JustDone can chat with PDF, DOC and TXT files and includes research tools beside writing help. Grammarly works in more everyday writing locations, but JustDone gives students a broader study workspace. |
| Copyscape | JustDone combines plagiarism checks with AI detection, humanizing and research. Copyscape is better for simple web-copy searches, while JustDone offers more tools around the result. |
Cons
Compared with |
Where this product may fall short |
|---|---|
| Quetext | Quetext has a continuing free plan and a clearly priced checker-only option. JustDone's seven-day offer renews at a higher monthly price, so the billing terms need closer attention. |
| Grammarly | Grammarly has mature browser and document integrations for daily editing. JustDone asks users to work inside a larger study platform, which can feel heavier for simple proofreading. |
| Copyscape | Copyscape uses pay-as-you-go checks and does not require a writing-suite subscription. JustDone may cost more than necessary for someone who only checks copied web text occasionally. |
Reviews
- MPGone review: The review says users often find the interface quick and easy, and several found the plagiarism checker adequate. It also reports inconsistent AI scores and false positives, especially when teachers try to use the result for grading.
- Trustpilot: TrustScore 4.5/5 from 8,908 reviews. Trustpilot's current summary says users often value the easy interface and help with writing tasks, while some report human-writing false positives and confusing output. The profile contains invited reviews, which readers should keep in mind.
- EM360Tech review: The reviewer says the humanizer changes sentence structure and keeps technical terms, but still needs proofreading and sometimes more than one pass. This source evaluates the humanizer rather than the plagiarism checker by itself.
- Reddit r/ask: The thread contains sharply different individual experiences. One commenter liked the humanizer, while others reported very high AI scores on their own writing and suspected the detailed report was part of an upsell. Apify recovered the matching post and exact comments.
