Tool Information
GPT Radar provides AI-generated text detection or authenticity analysis according to its service. Users should treat scores as uncertain signals, test false positives across languages and genres, inspect source and writing evidence, protect submitted text, allow explanation and appeal, and never punish someone solely from an automated result.
Begin with authorized, non-sensitive inputs and a limited test. Configure privacy, access, quality, export, disclosure, evaluation, consent, moderation, security, and spending controls; compare results with authoritative sources and real requirements; correct errors; and keep a responsible person in control before publication, deployment, grading, legal work, purchases, automation, or consequential changes.
Paid usage starts from $0.02. Scans, characters, API calls, credits, minimum purchases, expiration, and billing terms vary.
AI output or detection scores may be inaccurate, generic, biased, incomplete, stale, unsafe, or misleading. Review privacy, retention, training, copyright, consent, security, renewals, refunds, and commercial rights, and require qualified human review for legal, government, education, finance, communications, code, or other high-impact work.

Cons

- The site requires at least four hundred words for results it calls reliable
- No detector can prove who authored a passage
- Original human prose can receive a false AI classification
- Edited AI text can evade statistical detection
- Non-native speakers and formulaic professional writing face elevated false-positive risk
- A score must never be the sole basis for discipline; rejection; or accusation
- The service gives no public independent accuracy benchmark
- Detection performance changes as generation models evolve
- Submitted confidential text becomes customer data processed by a third party
- The terms permit analysis of service and customer-derived usage information
- The API is limited to one call per second by default
