What Undetectable.AI does
Undetectable.AI is a private SaaS company founded in 2023 that operates a freemium platform for AI-content detection and humanization, targeting students, bloggers, SEO professionals, and freelance writers who need to verify or disguise AI-generated text. Its core products include a free AI Detector (claiming 99%+ accuracy in a peer-reviewed NCBI-indexed study), an AI Humanizer that rewrites AI text to bypass Turnitin and Originality.ai, the TruthScan AI Image Detector (97.5% on Midjourney, 96.71% on DALL-E per external testing), and a Chrome Extension bundling five AI tools across 50+ websites.
The underlying technology combines linguistic, semantic, and pattern-analysis NLP models trained on outputs from ChatGPT, GPT-4/5, Claude, Gemini, DeepSeek, and Llama, with computer-vision models for image provenance and a recommendation engine (Writing Style Replicator) that profiles user tone and structure. The platform offers 30+ utilities spanning detection, humanization, paraphrasing, essay generation, citation, and plagiarism, supported by a privacy-first architecture that does not retain user text or training data.
The business model is product-led growth: a free no-signup detector drives top-of-funnel acquisition, converting to subscriptions at $5/month annual or $19/month monthly, supplemented by a $5/month Human Typer add-on, custom-priced Business Solutions for teams, and an API in early-adopter testing. Distribution is global via web and Chrome Web Store, with a reported user base of 23M+ and 41,316 new users joining per week. The company is bootstrapped, led by founder and CEO Christian Perry, and headquartered in the United States.

- Copyleaks: Direct competitor in AI content detection and plagiarism, serving both enterprise and education customers. Cited as a comparison point in Undetectable.AI's accuracy benchmark table and competes on similar enterprise detection use cases.
