Originality.ai
Collingwood, Ontario, Canada
What it is
Originality.ai offers tools for checking AI-generated text, plagiarism, facts, readability, grammar, spelling, and content quality. Its free Basic plan provides three AI scans per day, with up to 2,000 words per scan. The AI detector has configurable allowances of 0%, 5%, 15%, 25%, or 40%. A website scanner can crawl a site, identify pages likely to contain AI-generated content, and run scheduled scans. The browser extension scans Google Docs, web pages, or selected text, and includes writing replay, typing behavior insights, and shareable reports. A REST-based API can submit text for AI and plagiarism scans and return detailed results; the maker says AI detection supports 30 languages. API AI scans require at least 50 words, and the help page says accuracy decreases below 100 words. Originality.ai describes detection results as probabilistic estimates that may produce false positives or false negatives, not conclusive proof. Pro costs $12.95 a month billed yearly at $155.4, with a monthly billing option at $14.95/month. The product is available through web, API, and extension.
