About

What is NotGPT: AI Detector & Humanize?

NotGPT is a mobile application designed to detect AI-generated text and images, providing probability scores to indicate the likelihood of AI origin. It also features a 'Humanize' tool that rewrites AI-like content to make it sound more natural and authentic, offering three intensity levels: Light, Medium, and Strong. This helps users reduce AI-likeness scores significantly while preserving original intent and tone. The tool supports AI text detection in 12 languages and offers language-agnostic image detection. NotGPT prioritizes user privacy, ensuring that submitted text and images are not stored on servers after analysis, with only anonymized history summaries kept locally on the user's device. It's available on both iOS and Android, catering to students, creators, and teams who need to maintain content authenticity.

FAQs

What is the accuracy of NotGPT's AI detection?

NotGPT benchmarks against mainstream AI models like GPT-4, Claude, Gemini, and Llama, analyzing linguistic patterns. Accuracy improves with longer text (200+ words). It provides probability scores rather than binary verdicts, as no AI detector is 100% certain.

What does the Humanize feature do and how effective is it?

The Humanize feature rewrites AI-generated text to sound more natural, with Light, Medium, and Strong intensity levels. It can reduce AI-likeness scores from typical 60-80% down to under 20% in most cases, while preserving your original intent and tone.

What AI models can NotGPT detect?

NotGPT detects content from major LLMs including OpenAI’s GPT-3.5 and GPT-4, Anthropic’s Claude, Google’s Gemini, and Meta’s Llama. It analyzes common linguistic patterns rather than targeting specific models, ensuring effectiveness as new models emerge.

What languages does NotGPT support for text detection?

NotGPT supports AI text detection in 12 languages: English, French, Spanish, Portuguese, Dutch, German, Polish, Italian, Romanian, Indonesian, Tagalog, and Chinese (Simplified). Image detection is language-agnostic.

Is NotGPT free to use, and what are the paid options?

NotGPT offers a free plan with 2 detections per day for both text and images. Paid plans for unlimited detections, humanize rewrites, full history, and priority support start at $4.99 per week, $9.99 per month, or $79.99 per year.
