Free ChatGPT Detector

Proofademic analyzes writing for patterns associated with ChatGPT and other language models, then provides document-level and sentence-level estimates. No detector is infallible, so results should support a broader human review.

Human writing can share predictable or formulaic patterns with generated text, especially in short, highly structured or heavily edited passages. This is why a detection result should be reviewed with the writing context and never treated as proof by itself.

Detectors use different training data, models and decision thresholds, so their estimates can differ. The result is a probability based on writing patterns, not a direct record of how the text was created.

Not reliably. A detector can estimate whether writing resembles patterns associated with ChatGPT or other language-model output, but it cannot establish the exact model or authorship from the text alone.

Paste the essay into the detector or upload the supported document. Review the overall estimate, then inspect individual sentence signals and compare the result with sources, drafts and writing history.

Schools can use individual scans for close review and Batch Scan for larger sets of submissions. Results should be interpreted under a clear institutional policy and should not be the sole basis for a misconduct decision.

Teachers need tools that provide more than a single percentage. Proofademic is designed for academic writing and includes sentence-level review, multilingual detection, Batch Scan and shareable or exportable reports.

Paraphrase Shield is included across plans and is designed to identify AI-generated text that has been rewritten. There is no separate public benchmark for this feature, so it should be treated as another review signal rather than proof.

Proofademic detects AI-written patterns from major model families, including ChatGPT and GPT-family outputs. Product coverage evolves as models change, and the current detector should always be interpreted probabilistically.

The free offer is a one-time allowance of 1,000 words with no credit card required. Paid plans provide larger monthly allowances and per-request limits.
