Paid AI detector for publishers
Best Originality.ai Alternative
Originality.ai is a paid detection platform aimed at publishers, agencies, and SEO teams. It combines AI detection with plagiarism scanning, readability scores, and fact-checking aids, and adds workflow features those buyers need: team seats, a site-scanning tool, a Chrome extension, and an API. There is no ongoing free plan — you buy pay-as-you-go credits or a subscription.
Why switch from Originality.ai?
You get a real free tier: Originality.ai requires purchased credits for essentially everything; aicheckr’s core detector is free every day.
Right-sized for individuals: no team seats, site scans, or credit packs to manage — most students and teachers never need agency workflow features.
Sentence-level results without a paywall: per-sentence probabilities and a confidence band are on the free tier.
Rewrite tools included: an integrated humanizer and paraphraser, which Originality.ai deliberately does not offer.

Our verdict
Originality.ai is the professional publisher’s tool, and at agency volume its pricing makes sense. But if you are an individual who occasionally needs a trustworthy AI check, buying credit packs is paying for infrastructure you will not use. aicheckr covers that individual use case free, with sentence-level evidence — and writers often use it to pre-check work before it hits a client’s Originality.ai scan.
