ZeroGPT
Free, multilingual AI detector, ideal for a quick initial check
Overview
ZeroGPT is an AI text detector accessible without signup, with an interface available in multiple languages including English. It detects content produced by ChatGPT, GPT-4, Bard, Llama, and other LLMs, displaying an AI percentage and highlighting suspicious passages.
The free version is generous for occasional use. Paid plans (starting at ~$8/month) remove volume limits and provide API access for third-party tool integration.
Our verdict
ZeroGPT works well for a one-off check and is free, especially appealing to SMEs unwilling to subscribe. But its accuracy trails premium tools: false positives are common on technical or highly specialized text. Reserve for informal checks, not disciplinary procedures or legal commitments.
