FAQ
Does it guarantee passing AI detectors?
No. Results depend on the text, domain, and how detectors change over time. Treat any “detector score” as a signal, not a promise.
What’s the difference between modes like Ninja and Ghost?
They are rewrite styles with different strengths and targets. One may focus on subtle, human-like edits; another may aim for deeper restructuring. Try both on your own samples to see which fits.
Is my data private?
The tool is designed with privacy in mind. For sensitive content, avoid pasting personally identifiable or confidential information, and consider redacting details before processing.
What languages are supported?
English is the primary focus. Other major languages are often supported to varying degrees; always review outputs for nuance and correctness.
Can I use it for academic submissions?
Use it ethically—for clarity and editing—without misrepresenting authorship or violating academic policies.
How long can my input be?
Free tiers usually allow shorter inputs with daily limits; paid plans increase the per-request and monthly volume. If you have very long documents, process them section by section and maintain consistency in tone.
Will it keep my brand voice?
Humanized outputs aim to sound natural, but any strong rewrite can drift. Provide a short style note and do a final manual pass to lock in voice.
