| If you are… | Get | Why |
|---|---|---|
| Occasional individual scanners | Free | Includes 10,000 words monthly, one advanced scan and five Chrome extension AI highlights. |

04Is GPTZero worth the money?
At $12.99 per month on annual billing, Premium is a relatively accessible entry point. GPTZero describes a broader toolkit that includes AI detection, plagiarism checking, writing feedback and document replay. But the free plan is constrained, and usage caps may matter more than the headline price. We would not treat a detector score as an authorship verdict: GPTZero should be a signal, not proof. Compare the limits with your scanning volume before committing.

The published pricing information does not list a promo code for Premium. It does advertise 45% savings with annual billing: Premium is listed at $12.99 per month annually, compared with $23.99 when billed monthly.
