In their own words
AI Detector Pro
AI Detector Pro is a web product for identifying signs of AI in documents and revising or humanizing text. For English documents, it highlights passages likely to trigger AI detectors and shows predicted text and overused AI phrases. Detection is listed for English, Spanish, French, Arabic, German, Korean, and Portuguese writing. AI Eraser suggests English wording changes, with a choice about how much to revise. Other tools include tone analysis, phraseology, and a pinpoint editor. The Free plan includes three AI scans per month and no humanizations. Basic allows 103 scans per month, while Unlimited provides unlimited scans; both list unlimited humanizations, multilingual detection, the editor and tone analysis, as well as Word and Google Docs plugins. API access requires an eligible subscription: report requests cost $0.09 per unit of up to 4,000 characters, and other endpoints are free. The company says user text may be shared with third-party AI models for core functionality. User content is automatically deleted at the beginning of the fourth month after entry, while documents created with the product remain until the user deletes them or the account is deleted. The site cautions that model randomness can lead to incorrect identifications or humanizations.
AI or Not
AI or Not offers detection for AI-generated images, text, video, audio, and deepfakes through its web and iOS service and API. Its image detector examines pixel-level information and can return an AI verdict, generator breakdown, and separate deepfake signal. Listed image sources include Nano Banana, Midjourney, DALL·E / GPT Image, Stable Diffusion, Flux, and Grok / Aurora; the coverage date given is July 2026. The image detection page states a 95th-percentile response time of one second or less. An MCP server supports Claude Code, Claude Desktop, Cursor, Codex, VS Code, and Windsurf for detection and batch scanning, and the service links to a Python SDK and REST API documentation. MCP text analysis rejects inputs shorter than 250 words. AI or Not says checked content is deleted instantly. Its iOS privacy policy says text analysis runs on-device, with no account required and no transmission of text or results. The Free plan includes $5 in credits, 1 million words of AI text detection each month, 20 AI image checks, and an API key. Pro costs $5 USD per month and includes $10 in monthly credits; Enterprise pricing is custom and lists regional cloud hosting and an on-premises option.
