Slop or Not vs Originality.ai: AI Detector (2026)
Originality.ai is built for agencies burning through hundreds of articles a week — pay-as-you-go credits, sentence-level highlights, a full scan history. A teacher or writer checking one essay doesn't need a credit meter running: Slop or Not runs the same kind of check on iPhone or Mac free, with no credits to buy.
Originality.ai is a content QA platform for publishers and agencies that need AI text detection at volume. It uses pay-as-you-go credits at roughly 100 words each, with no free tier. The platform handles text only and routes all scans through its servers; Slop or Not checks AI-generated text and images on your iPhone or Mac without an account.

Where your text & images go
With Originality.ai, your submitted content is scanned and saved to your scan history, and it separately collects account data such as your name, email, and password. You can delete your scan history at any time, and an anonymized copy is only kept for testing and model training if you opt in. See the Originality.ai content-handling notes for details. Slop or Not keeps native checks on your iPhone or Mac, and online checks run on Numen's own Apple hardware and are deleted after processing.
Where Slop or Not Fits
Skip the credit purchase: Slop or Not checks the same essay on iPhone or Mac at no cost per scan, with nothing metering the word count.
- Slop or Not runs its own detection models, so no third-party AI provider sees your text or images. Native checks run on the Apple Neural Engine; online checks run on Numen's self-hosted Apple hardware, and submissions are deleted after processing.
- Free daily checks in the iPhone and Mac app and in the free online checker. Pro removes the daily cap, and native checks have no per-document word cap.

More From Numen
AI can now fake a profile photo or wrap a scam in a link that looks safe to tap. Numen builds the apps that put you back in charge: spot AI-generated text and images with Slop or Not, run the best open-source models uncensored and private with Private LLM, and strip trackers from links and QR codes before they follow you with Clean Links.
One belief runs through all three: your data belongs to you, and no one else.
