Limits at a glance
- Quota reset: Humanizer and Image generation are on a daily basis, while AI Chat and other quotas do not have a reset period stated on the official website.
- Commercial use: Allowed
- Conditions: Free to use with rewriting, no registration required; some features and higher quotas require account registration; official notes that platform restrictions may vary.
Watch out for this
The free rewriting service only allows 125 characters per use, has only 2 modes, and will be cut off for long texts. Plagiarism detection has no free quota, so do not expect the free version to be able to check reports for plagiarism.
When the free quota is insufficient, how much does it cost to pay for it?
| Plan | pricing | Description |
|---|---|---|
| Premium (Monthly) | US$19.95 / mo | US$19.95/month |
| Premium (semi-annual payment) | US$13.33 / semi-annual | Equivalent to US$13.33/month, billed US$79.95 semiannually |
| Premium (Annual) | US$8.33 / mo (Annual subscription) | The original price is equivalent to US$8.33/month (US$99.95/year). As of the check on 2026-08-28, there is a limited-time promotion of 40% off until 9/6, which reduces the annual payment to US$5.00/month, and the price will revert to the original after the promotion. |
