A value-focused detector with broad integrations, API access, and useful verification tools.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
AI Detectors.io is a web-based content authenticity platform for students, educators, writers, publishers, and editorial teams. It analyzes writing for signals associated with AI-generated content, then presents AI probability scores, confidence ratings, and sentence-level highlighting. Detection covers major models including ChatGPT, Claude, Gemini, and Llama, while additional tools support paraphrasing, humanization, citation verification, plagiarism checking, grammar work, document uploads, and text scanning. It suits users who want detection alongside broader content-review functions.
Pricing is straightforward across two plans. Free provides 10,000 words per month, 500 words per use, a Basic AI Detector, and one free credit added daily. Premium costs $8.33 per month with annual billing and includes 500,000 words per month, 25,000 words per AI Detector scan, an Advanced AI Detector, and unlimited daily credits. The paid tier is therefore aimed at regular reviewers who need higher monthly capacity and larger individual scans, while the free plan fits lighter or occasional checks.
Its platform coverage is a major part of the product’s appeal. AI Detectors.io works on the web, through a Chrome extension, and via a REST API that returns JSON results and model attribution. Integrations include Google Docs, Google Classroom, Gmail, LinkedIn, WordPress, Medium, Canvas, Blackboard, and Moodle, giving educators, publishers, and content teams several ways to bring detection into existing workflows. Choose it if integrations, sentence-level evidence, and multiple verification tools matter. Users handling documents above 25,000 words in one detector scan should look for a workflow designed for larger single-pass analysis.
