Our verdict on Undetectable AI

Undetectable AI is a web-based platform for assessing whether text is likely AI-generated. It is designed for students, educators, writers, marketers, researchers, and businesses that need to review pasted text, uploaded files, documents, or URLs. Detection covers writing associated with ChatGPT, GPT-4, GPT-5, Claude, Gemini, DeepSeek, and Llama, with multilingual support across 50+ languages. Users can also access detection through a Chrome extension or API.

Pricing follows a freemium model, with a free plan and paid monthly tiers based on word allowance. The 10K words/month plan costs $9.99 per month and includes unlimited AI detecting, API compatibility, and unlimited Human Auto Typer. The 20K words/month plan costs $19 per month, the 35K words/month plan costs $31 per month, and the 50K words/month plan costs $42.5 per month; each lists the same three highlights. The platform supports Google Docs, LinkedIn, Gmail, Microsoft Word Online, Notion, ChatGPT, Claude, Twitter, Facebook, Medium, and WordPress, giving content teams multiple workflow entry points.

Its main strength is breadth: AI model coverage, multilingual detection, file analysis, URL scanning, bulk document processing, AI detection scores, detailed result insights, browser access, and API workflows are combined in one product. The API also supports PDF detection. Teams that need integrations, recurring scans, or automated workflows should consider Undetectable AI, while users seeking only a basic standalone text check may not need its wider feature set.
