Slop or Not vs Proofademic: AI Detector (2026)

Proofademic gives a sentence-level score built for grading dashboards — useful once a teacher is triaging a stack of essays through a browser tool. For one suspicious essay, Slop or Not skips the 1,000-word free-tier ceiling and the 3-day trial clock entirely: check a full essay on-device with no per-document word cap.

Proofademic is a browser-based AI-text detection platform built for educators, students, and institutions. It offers sentence-level analysis and batch scans; text is processed on a remote server. Slop or Not runs the check directly on your iPhone or Mac, so a student essay never leaves your device.

Where your text & images go

With Proofademic, text or documents you submit (its policy calls this "Content Data") are processed by its AI models, along with account and payment data. Its policy defines submitted text and documents as "Content Data"; check it for how long submissions are stored and whether they are used to improve its models, which its public pages do not summarize clearly. See the Proofademic privacy policy 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

Slop or Not clears Proofademic's 1,000-word free-tier line without blinking — the native app has no per-document word cap at all.

  • 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.

Common Questions

Is Slop or Not a replacement for Proofademic?

No — it replaces the private Apple-device spot-check workflow, not the full browser-based academic platform.

Which one is better for a teacher checking one suspicious essay?

Usually Slop or Not, when privacy and long-document checks matter more than dashboards or sentence-level web reports.

Can students use Slop or Not to check their own work?

Yes — students can run a check on a full draft privately on iPhone or Mac before submitting.

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.
