If you need to screen a draft for likely AI-written text, ZeroGPT gives you a fast score and highlighted passages.
ZeroGPT is worth using free, but paying only makes sense at $9.99 a month for frequent long checks; it is cheaper than GPTZero, with less confidence for high-stakes calls.
Who it's for
ZeroGPT suits you if you need a quick first pass on raw AI-assisted drafts. You will be disappointed if you need evidence to challenge a writer, student, or contractor.
Buy it if
- You screen raw blog drafts before publishing client work.
- You already use ChatGPT for first drafts and want a quick warning before editing.
- You need to review uploaded documents before a short deadline.
Skip it if
- You must make an academic, hiring, or disciplinary decision from the result.
- You edit mixed human-and-AI drafts and cannot tolerate inconsistent scores.
- You need authorship evidence rather than a probability-based text scan.
Your first hour
You can run a basic scan without an account or card. There is no documented trial for paid tiers, and a first result usually appears within a few seconds.
- Paste a draft The free detector accepts up to 15,000 characters in one check.
- Read the score Independent reports place a typical scan at about 2–3 seconds.
- Try file batches The free option allows up to 5 batch files for detection.
- Save a report PDF detection reports are included with paid subscriptions.
The learning curve is close to zero: paste text, read the result, then decide whether it needs human review.
What you actually get per plan
ZeroGPT has a free option, three paid subscriptions, and a quote-based enterprise option. Most solo users who pay will land on Pro for its 100,000-character checks, though Plus is the first tier with recurring plagiarism words.
| Plan | Price | What’s inside | Catch |
|---|---|---|---|
| Free | Free | 15,000 characters per detection; 5 batch files; 1,000 ZeroCHAT-4 prompts | Ads and upsell prompts |
| Pro | $9.99/month | 100,000 characters per detection; 50 batch files; 2,000 ZeroCHAT-4 prompts | $7.99 monthly rate requires annual billing; plagiarism allowance is 750 words once |
| Plus | $19.99/month | 100,000 characters per detection; 60 batch files; 25,000 plagiarism words per month | $14.99 monthly rate requires annual billing |
| Max | $26.99/month | 150,000 characters per detection; 75 batch files; 40,000 plagiarism words per month | $18.99 monthly rate requires annual billing |
| Enterprise | Quote | Custom solutions; API integration; enterprise data controls | Quote required |
The free plan caps each detection at 15,000 characters, which is enough for a short article but not a long manuscript.
Three real situations
These are the cases where the subscription either earns its place or does not.
A freelance writer with three retainer clients
They can run a short client post through the free 15,000-character check before delivery. Pro costs $9.99 monthly when longer drafts and batch uploads become routine.
A creator with a weekly newsletter
ZeroGPT can flag an unedited AI draft quickly, but edited copy may receive inconsistent scores. It does not replace the creator’s own editorial judgment.
A two-person online store checking product copy
A paid plan is not the right buy for occasional checks. The $0 detector and its 15,000-character limit are the simpler route for two people reviewing drafts themselves.
Where it falls short
Reviewers report high false positives, especially for non-native English prose and heavily edited human work. They also report inconsistent scores on identical documents and weaker results on mixed human-AI text. GPTZero is the more cautious choice for high-stakes review because its results are generally more stable.
The annual discount requires paying upfront, while refunds have very short windows. Reviewers also report unresponsive support. Privacy-conscious teams should note that ZeroGPT says scan text is discarded and not used for model training, but it collects technical data for security and analytics.
Watch out: Monthly refund requests must be sent by email within 6 hours of purchase. The FAQ gives yearly buyers 10 hours, while the terms mention 12 hours for a mistaken yearly subscription.
Common questions
Is there a free ZeroGPT plan?
Yes. The free detector allows up to 15,000 characters per check and does not require an account for a basic scan.
Can I cancel ZeroGPT any time?
You can cancel to stop future renewals. After the refund window passes, ZeroGPT says it does not issue a partial refund for the current billing period.
Does ZeroGPT train on my text?
ZeroGPT says submitted text is processed for the result, then discarded. It says the text is not shared, published, or used to train its detection model.
What is the cheapest way to try ZeroGPT?
Use the free detector first. The vendor does not offer a documented free trial of paid subscriptions.
What is the closest ZeroGPT alternative?
GPTZero is the best-known comparison. Choose GPTZero instead when a false positive could harm a client, student, applicant, or employee.
Bottom line
Use ZeroGPT free for quick checks on raw drafts. Buy Pro at $9.99 monthly only if you need larger checks often; skip it for accusations, academic decisions, or any work where a false positive has consequences.
