ZeroGPT is one of the most popular AI detectors out there, but it has a reputation for false positives. iLang Detect takes a different approach: it's free, requires no signup, and gives you detailed sentence-level feedback on six dimensions of your writing. So which tool actually helps you improve your text?
ZeroGPT bundles a whole suite of tools, from plagiarism checking to a humanizer, but its detection accuracy is based on internal claims with no published methodology. iLang doesn't just give you a score. It explains what's wrong with each flagged fragment and suggests specific fixes. If you want to understand why your writing looks AI generated, iLang is the better choice.

Where they differ
Free vs. freemium model
ZeroGPT offers a free tier with a 15,000 character limit and a monthly word allowance, but you'll need to pay for higher limits and batch features. iLang is completely free with no signup and no limits. You can use it as much as you want without ever entering a credit card. That simplicity matters for writers who just want to check and fix text quickly.
Score vs. actionable feedback
ZeroGPT highlights sentences and shows an AI percentage gauge, but it doesn't tell you what to change. iLang goes further: every flagged fragment comes with a problem explanation and a fix suggestion. It covers vocabulary, structure, tone, punctuation, logic, and rhythm. You get a clear path to improve your writing, not just a number.
Accuracy claims and transparency
ZeroGPT says it pushes toward 98% accuracy on internal evaluations, but it doesn't publish its methodology. The tool also has known false positives, like labeling the US Constitution as AI generated. iLang doesn't make bold accuracy claims. Instead, it focuses on helping you understand why something might be flagged, so you can decide for yourself.

ZeroGPT gives you a paraphraser, summarizer, grammar checker, humanizer, and even an AI chat bot. If you want one platform to handle AI detection, rewriting, and translation, it's a solid option. The free tier covers up to 15,000 characters per check, which is enough for many students and casual users.
