JustDone presents itself as an all-in-one AI writing platform, with an AI humanizer, an AI detector, a plagiarism checker, and other writing tools. Its humanizer is promoted as rewriting AI-generated text so it reads naturally, with a built-in option to re-check the result using JustDone's own AI detector.
We tested both the AI humanizer and the AI detector against major AI detectors, and reviewed JustDone's pricing and sign-up flow.
Key Findings
- The AI humanizer failed every detector we tested, including JustDone's own detector.
- The AI detector worked well on basic tests, correctly identifying AI and human text.
- There is no free plan. "Try JustDone" leads to a paid 7-day trial that auto-renews at $29.99 per month.
AI Humanizer
We ran a standard ChatGPT-generated sample through JustDone's AI humanizer, then checked the "humanized" output with seven AI detectors.
| Detector | Result |
|---|---|
| GPTZero | ❌ 100% AI |
| ZeroGPT | ❌ 100% AI |
| Copyleaks | ❌ 100% AI |
| Turnitin | ❌ 100% AI |
| QuillBot | ❌ 100% AI |
| Originality AI | ❌ 100% AI |
| JustDone | ❌ 100% AI |
The humanizer failed to bypass every detector. Even JustDone's own detector flagged the rewritten text as 100% AI, after the humanizer had labeled the same text as human.
The quality of the rewritten text also suffered. Sentences lost clarity and consistency, which left the output with awkward phrasing and unnatural structure. Instead of making the text sound more human, the tool made it harder to read.
AI Detector
Earlier versions of JustDone's AI detector produced inconsistent results. It has since improved, and in our tests it performed well on standard detection tasks.
| GPT-5 Text | Human Text | Verva Text |
|---|---|---|
| 100% AI | 0% AI | 0% AI |
- GPT-5 text was correctly flagged as AI-generated.
- Human writing was correctly identified as 0% AI.
- Text humanized with Verva's AI humanizer passed as human.
For quick, basic checks, JustDone's detector is a reasonable option. It doesn't offer much beyond other detectors, and it isn't ideal for academic or high-stakes use.
Pricing and User Experience
JustDone's interface looks modern and well organized, but the sign-up flow is restrictive. Clicking "Try JustDone" takes you straight to a pricing page instead of the tool.
| Plan | Price |
|---|---|
| 7-day Access | $2.00 for 7 days, then auto-renews at $29.99 per month |
| Pro Monthly | $19.99 per month |
| Pro Annual | $119.88 per year ($9.99 per month) |
There is no free plan. The 7-day option is selected by default, and it renews at $29.99 per month, a higher monthly price than the regular Pro Monthly plan. If you only want to try the tool, remember to cancel before the 7 days end.
Scorecard
| Feature | Score | Notes |
|---|---|---|
| AI Humanizer | ⭐☆☆☆☆ (1/5) | Failed every detector and reduced text quality |
| AI Detector | ⭐⭐⭐⭐☆ (4/5) | Accurate for basic detection |
| Pricing & UX | ⭐⭐☆☆☆ (2/5) | No free plan; trial renews at a higher price |
Overall: ⭐⭐☆☆☆ (2/5)
Final Verdict
JustDone's AI detector is decent for quick checks, but its AI humanizer is among the weakest we have tested. It failed to bypass GPTZero, Turnitin, ZeroGPT, Copyleaks, and even JustDone's own detector, and the rewritten text read worse than the original.
With no free plan and a trial that renews at $29.99 per month, it is hard to recommend JustDone for humanizing AI text.
If you need an AI humanizer that bypasses AI detectors, try Verva's humanizer.
