Originality.ai

Content review toolkit with AI-detection estimates, plagiarism checks, readability, grammar, and editorial quality tools.

Scan content, inspect the report, and corroborate concerns rather than treating an AI-detection score as proof of authorship.

Access and pricing: Basic is free for AI detection: three scans/day, up to 2,000 words/scan. Paid plans add credit-based checks; detection results can be wrong.

What it does well

Originality.ai combines AI detection with plagiarism, readability and grammar checks in one workflow. The free Basic plan covers AI detection only, supports file upload (docx, pdf, doc) and allows 3 scans a day at up to 2,000 words each. Paid plans add full site scans, team management, tags and a Chrome extension.

Who gets the most from it

Pro costs $12.95 a month billed yearly or $14.95 billed monthly and includes 2,000 credits a month. Enterprise adds 15,000 credits, 365 days of scan history, a dedicated customer success manager and API access.

Limits to check before you commit

Credits cover 100 words each: an AI check uses 1 credit per 100 words and an AI plus plagiarism check uses 2. Pro and Enterprise credits expire at the end of each month, while pay-as-you-go credits expire two years after purchase. API access is listed under Enterprise, and the page was unclear about Pro. Detection scores are estimates, so use them as one input and corroborate before drawing conclusions about authorship.
