Overview

About Originality.AI

Originality.AI scans submitted text for signs of machine generation and for copied passages, returning a per-sentence score and a shareable report. Around that core it adds team workflow: per-writer scan history, site-wide crawling, and a Google Docs replay that reconstructs the typing process from revision history. Scanning is billed in credits where one credit covers 100 words, and API access sits on the higher tier.

How we collect these records

Editorial verdict

Pros & cons of Originality.AI

high confidence

The detector to pick if you are a publisher or agency policing freelance output at volume, because the team history and writing replay matter more than the raw score. A free Basic tier (three AI-only scans a day, 2,000 words each) now lets you test it before paying. Do not use it to accuse a student; no detector is accurate enough to carry that weight.

Pros

Credit model is legible: 100 words per credit, no hidden weighting
API on the higher tier makes batch pipelines possible
Chrome extension works inside Google Docs, where the writing actually happens
Writing replay from revision history is process evidence, not just a score
Free Basic tier allows three AI-only scans a day with file upload, no subscription needed

Cons

Monthly subscription credits expire, so a light month is wasted spend
The jump from $14.95 to $179 a month is a steep single step
False positives on heavily edited or non-native English writing are a documented hazard across every detector
Accuracy benchmarks are largely vendor-run

Best for

Content agencies auditing freelance submissions before they pay for them
Publishers sweeping large archives for machine-written pages
SEO teams screening acquired, syndicated or outsourced content

Not for

Academic misconduct decisions about an individual student
Non-English text, where detector accuracy drops sharply
Anyone expecting a definitive yes or no rather than a probability

Watch out: Scores are probabilistic, and treating a high AI reading as proof has already produced real disputes, so pair it with process evidence rather than acting on the number alone.
