Slop or Not
Use it for people who want native Apple checks or the free online checker for text, images, and provenance clues.
AI Detector
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.

| Evidence level | Probability verdict plus provenance signals, with internal-test caveats instead of 99.9% certainty claims | Sentence-level scoring is described |
| Browser checker | Free online checker runs in any browser on Numen's private Mac server; submissions are deleted after processing | Web AI text detector |
| Native Apple app | Native iPhone and Mac app for on-device checks; browser users can use the free online checker | No |

| Privacy | Native checks stay on the iPhone or Mac and never send submitted text or images to a third-party AI provider. Online checks run on Numen's own Apple hardware, and submissions are deleted after processing. | Its policy defines text or documents submitted for AI processing as "Content Data"; retention and training terms are set out in that policy |
| Main limitation | On-device privacy requires iPhone or Mac; browser checks run on Numen's private Mac server, not on-device | Free tier starts at 1,000 words; larger use moves to paid word plans |

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.
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 is not the right answer for every workflow — pick the tool whose strongest workflow matches the check you need to run.
Use it for people who want native Apple checks or the free online checker for text, images, and provenance clues.
Use it for students and educators checking essays before submission.
No — it replaces the private Apple-device spot-check workflow, not the full browser-based academic platform.
Usually Slop or Not, when privacy and long-document checks matter more than dashboards or sentence-level web reports.
Yes — students can run a check on a full draft privately on iPhone or Mac before submitting.
Keep comparing adjacent tools before you pick a workflow.
GPTZero lives in Canvas and Google Docs and never leaves the browser — and it never checks an image, despite the 'AI Vision' name.
ZeroGPT needs no account and returns a verdict in seconds, but paste in more than 15,000 characters and it stops reading.
Originality.ai tracks every scan in a dashboard built for agencies, but there's no free tier — every check burns a credit at roughly 100 words apiece.
Copyleaks plugs into seven different LMS platforms and even flags deepfake video, but the sentence-level detail and full reporting sit behind an enterprise account.
Winston AI bundles plagiarism checks and writing feedback with its AI verdict, but the free lite checker stops at 2,000 characters and the real trial runs out in 14 days.
Turnitin's AI-writing indicator is built into a workflow schools already trust, but there's no public version — access runs through a school subscription or not at all.
Privacy tools from the same team
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.
