Slop or Not
Use it for people who want native Apple checks or the free online checker for text, images, and provenance clues.
AI Image Detector
AI or Not opens its API to a single developer with no payment method required to start, useful for a side project or an early prototype. Hive Moderation asks for a card on file before the free credits unlock, a fair trade once the workload looks like a real moderation pipeline instead of a test.
AI or Not and Hive Moderation are both API-first multimodal detectors covering images, video, and text, but they aim at different scales. AI or Not is accessible to individual developers: the free plan includes starter credits and a capped number of AI image checks per month with no payment required to start. Hive Moderation is built for enterprise trust-and-safety pipelines; free credits require adding a payment method. For a personal check without an API key, Slop or Not runs text and image detection on iPhone and Mac on-device.

| Feature | |||
|---|---|---|---|
| Best fit | On-device iPhone and Mac checks or free browser checks for text and images | Developers who need API detection for several media types | AI-generated and deepfake content detection for moderation pipelines |
| Text detection | Checks writing in the native app and online checker | Text detection is listed with image, music, video, and deepfake checks | Documentation describes AI-generated detection for image, video, text, and audio |
| Image detection | Checks photos, synthetic images, and provenance clues in the app or online checker | Image detection is listed and the upload demo supports image formats | Image and video AI-generated detection is listed |
| Deepfake detection | Covers deepfake and synthetic-image checks as image detection | Deepfake detection is listed for API and product pages | Deepfake detection is listed for image, video, and audio workflows |
| Metadata and provenance signals | Reads SynthID, C2PA, and IPTC signals in native and online image checks when a file carries them | Not publicly clear | Not publicly clear |
| Manual forensic tools | Reports detector and provenance evidence in native and online checks; not a manual forensic editor | No | No |
| Evidence level | Probability verdict plus provenance signals, with internal-test caveats instead of 99.9% certainty claims | Demo shows AI and deepfake percentage outputs and data breakdown | APIs return confidence scores |
| Browser checker | Free online checker runs in any browser on Numen's private Mac server; submissions are deleted after processing | Web upload demo is shown | Free AI detector Chrome extension is listed |
| Native Apple app | Native iPhone and Mac app for on-device checks; browser users can use the free online checker | No | No |
| API workflow | Pro Mac app includes a local CLI and MCP server; no public hosted API | API key is included on the free plan | AI-generated and deepfake content detection APIs are documented |
| Classroom workflow | Useful for checking student writing on-device in the app or through deleted-after-processing online checks | Not publicly clear | Not publicly clear |
| Free tier & limits | Free daily checks in the iPhone and Mac app and a free online checker in any browser. Pro removes the native daily cap; the native app has no per-document word cap. | Free credits to start, 1M words/month of text detection, and a capped number of free image checks per month. | Pricing page lists free credits after adding a payment method |
| 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 public privacy policy covers account, contact, and payment data; it does not specifically describe how images or text submitted for detection are collected or retained | Its public privacy policy covers account, billing, and analytics data; it does not specifically describe how content submitted to its detection APIs is collected or retained |
| Main limitation | On-device privacy requires iPhone or Mac; browser checks run on Numen's private Mac server, not on-device | Credit model for multimodal API use; free image checks are capped | Enterprise/API-first workflow for high volume processing |

Hive holds its free credits until a payment method is on file, and AI or Not still meters image checks past its starter tier. Slop or Not needs neither a card nor a key: open the app, check the file, done.
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 developers who need multimodal AI detection behind an API key.
Use it for platform teams that need AI-generated media detection in moderation pipelines.
Keep comparing adjacent tools before you pick a workflow.
AI or Not covers text, images, audio, video, and deepfakes behind one key, but every check outside the free credits draws down a balance a developer has to track.
Hive Moderation covers image, video, text, and audio detection for trust-and-safety pipelines, but the free credits don't unlock until a payment method is on file.
AI or Not covers five media types behind one key; Sightengine stays image-only but keeps a permanent free tier.
Hive Moderation screens everything at platform scale; Reality Defender specializes in deepfakes for security teams.
Sightengine offers a card-free permanent free tier; Hive Moderation gates its credits behind a payment method.
Sightengine reads C2PA and EXIF metadata alongside its AI-image and deepfake detection, but it's API-only, capped at 2,000 free operations a month, and it never checks text.
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.
