Introduction
JustDone promotes itself as an all-in-one platform for AI writing tools, including an AI detector and AI humanizer. The company claims its tools are fast, reliable, and ideal for students, professionals, and editors.
But how accurate are these claims? After testing both the AI detector and AI humanizer, the results reveal a mixed picture.
⚠️ Marketing Practices
JustDone’s marketing relies heavily on search-based advertising. They often target competitor keywords like TwainGPT, Undetectable AI, and similar tools to capture search traffic.
In one ad campaign, they used “Twain AI” as their H1 headline, a name belonging to a completely different company, while the ad itself was bidding on the TwainGPT keyword.
This type of marketing is misleading and gives a poor impression of the brand’s credibility.
🔍 AI Detector
In earlier versions, JustDone’s AI detector produced random or highly inconsistent results. Recently, however, it appears to have been upgraded and now performs more predictably.
While still not perfect, the tool can now correctly flag AI-generated text in most basic scenarios.
🧪 Detector Performance
| GPT-5 Text | Human Text | TwainGPT Text |
|---|---|---|
| 100% AI | 0% AI | 0% AI |
Results:
- GPT-5 text was correctly flagged as AI-generated.
- Human writing was accurately detected as 0% AI.
- TwainGPT text bypassed the detector completely.
Overall, the detector has improved and can handle standard detection tasks fairly well.
🧠 AI Humanizer
When tested, JustDone’s AI humanizer produced poor results, and its own detector contradicts its humanizer results.
For example, text labeled “100% human” by the humanizer was later flagged as 100% AI when scanned through JustDone’s own AI detector.
🧪 Humanizer Performance
| Tool Tested Against | Result on JustDone Text |
|---|---|
| GPTZero | 99% AI |
| Turnitin | 100% AI |
| Copyleaks | 100% AI |
| JustDone Detector | 100% AI |
Results:
- The AI humanizer does not bypass AI detectors.
- Even JustDone’s own system reverses its earlier “human” label.
- The inconsistency makes it unreliable for any use.
💰 Pricing
JustDone offers free access for basic usage, along with paid tiers for extended features.
The pricing structure is flexible, but given the performance issues, users may find more value in more reliable AI detectors such as GPTZero, Turnitin, etc.
✅ Pros and ❌ Cons
Pros
- Improved AI detector performance
- Free plan available
Cons
- AI humanizer produces poor results
- Marketing is confusing and misleading
🏁 Final Verdict
JustDone has improved its AI detector, but the platform still struggles with reliability and consistency. Its AI humanizer doesn't perform well and even conflicts with its own AI detection tool.
While the design and accessibility are decent, the performance doesn’t match the expectations. For dependable AI detection, tools like GPTZero, Turnitin, or Copyleaks remain better options. And for bypassing AI detectors, TwainGPT continues to outperform competitors.
