AI Detector Pro vs It's AI

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.

It's AI estimates whether text may have been written by a language model, including content associated with ChatGPT, Gemini, Claude, Grok, and other models. It also offers plagiarism, grammar, and spelling checks. Users can paste text or upload PDF, DOCX, and TXT files; the displayed limits are 200 to 500,000 characters. Deep Scan highlights sentences that appear AI-generated and provides a word heatmap showing which parts influence the score. Listed integrations include an API, Chrome Extension, ChatGPT Plugin, Python SDK, Canvas LMS, and Zapier; Moodle is marked as coming soon. The service is presented for teachers, students, institutions, and publishers, as well as writers, managers, recruiters, and ML engineers. It also offers enterprise API access and batch processing. The FAQ advises treating results as evidence alongside context, not as sole proof of AI use, and says content is not shared with third parties after checks are complete. The free plan is listed at free. Plus is listed at $84 a year, billed at $84/year and shown as $7 and $9/month with annual savings.
