ZeroGPT review

ZeroGPT is an AI-content detector wrapped in a broader set of writing tools. Its homepage says its DeepAnalyse technology checks text for signs of writing from ChatGPT, GPT-6, Gemini, Grok, Claude, DeepSeek and other models. The detector highlights sentences it considers AI-written and gives an estimated percentage of AI content; that score is an indicator, not proof of who wrote a passage.

The suite also includes an AI humanizer, plagiarism checker, paraphraser, summarizer, grammar checker and translator, along with image and video detectors. ZeroGPT says its plagiarism checker compares text against billions of sources. Other features include batch file uploads, PDF reports for detection results, API access and access through WhatsApp and Telegram. That breadth may suit someone who wants several basic writing utilities in one place, but the detector is the product’s central promise—and the part that deserves the most caution.

The clearest case for ZeroGPT is convenience: the homepage groups detection with rewriting, proofreading and originality tools, rather than offering a detector alone. You can check text, get a sentence-level indication of what the tool flags, and move to a paraphraser or humanizer without changing products. Batch uploads and generated PDF reports are also listed, which may help users handling multiple documents or needing a record of a scan.

There is a free plan to try, though it is tightly capped. According to the published pricing snapshot, it costs $0 and includes:

• 15,000 characters per AI detection scan and 1,250,000 AI-detection words per month.
• 300 plagiarism-checker words, one time.
• No batch files.

The pricing page advertises 40% off annual billing for Personal and Business / EDU plans, but does not publish those plans’ prices in the published information. Enterprise pricing is custom. The API is usage-based, with balances funded from the dashboard; listed API capabilities include batch inference and detection, plagiarism checks and text tools. That gives teams options beyond the free tier, but not a clear cost to compare upfront.

The main limitation is confidence in the detector, not a missing feature. Reddit users describe human-written work receiving high AI scores, including an academic paper excerpt and a passage from The Lord of the Rings. Those are user reports, not controlled accuracy measurements, but they underline why a ZeroGPT percentage should not be treated as evidence of authorship. Another Reddit discussion describes conflicting results across ZeroGPT, GPTZero and Turnitin; a score from one detector cannot guarantee what another will report.

The free tier also has practical ceilings: 15,000 characters per scan, zero batch-file uploads and only 300 plagiarism-checker words once. The larger 1,250,000-word monthly allowance applies to AI detection, not plagiarism checking. Paid Personal and Business / EDU prices are not published on the vendor's site, so buyers cannot compare those tiers on price from this information alone. We would consider ZeroGPT for its free writing utilities, but not rely on its detector score to settle a dispute or certify that text is human-written.

ZeroGPT’s Free plan is listed at $0 forever. It allows 15,000 characters per AI detection scan and 1,250,000 AI detection words per month, but batch uploads are capped at zero files. Plagiarism checking is limited to 300 words, one time.

The paid-plan jump is impossible to price from the published snapshot: Personal and Business / EDU plans are named, but their monthly and annual prices are not published there. The page advertises 40% off annual billing, but without list prices we can’t calculate the savings. Enterprise pricing is custom; API Business Plans are usage-based, with no rate listed. The API balance is funded from the dashboard.

No add-ons are listed in the published pricing data. It also doesn’t give paid-plan limits, so check those before switching from the free tier. The pricing snapshot is marked low confidence; confirm current prices and caps with ZeroGPT before budgeting.

ZeroGPT bundles detection with writing tools, including a humanizer, paraphraser and plagiarism checker. Switching to it may mean replacing several tools, but the published material does not describe imports, account migration or data export. Its PDF reports are generated per detection; that is not evidence of a full history or account export. Keep copies of anything you need before changing tools, and ask ZeroGPT what you can take with you.

If you’re leaving, the key question is whether another detector or writing tool fits your needs—not whether ZeroGPT scores establish misconduct. Our verdict is not to treat its detector score as proof.

We can’t say what makes users leave based on Reddit: no Reddit posts or comments were included in the published material. The paid-plan prices and limits are also unpublished in the published pricing snapshot, so confirm them before moving a team. Test a replacement on your own text before retiring any existing workflow; we have not compared detector accuracy.
