Hive Moderation vs Sightengine: AI Image Detector (2026)
Sightengine's free tier never expires: 2,000 operations a month, plus the C2PA and EXIF metadata reads Hive doesn't offer, no card needed to start. Hive Moderation skips the metadata detail and sells volume instead — image, video, text, and audio detection sized for a trust-and-safety team screening real traffic, once a payment method is on file.
Hive Moderation and Sightengine are both API-first image-detection services, but Sightengine is more accessible to individual developers. Sightengine offers a permanent free tier of 2,000 image operations per month; its detection covers AI-generated images, deepfakes, and C2PA metadata. Hive Moderation is pitched at enterprise trust-and-safety teams: free credits require adding a payment method, and the tooling targets high-volume pipeline integration. Slop or Not handles image checks on iPhone and Mac on-device, without an API key.

|---|---|---|---|
| Best fit | On-device iPhone and Mac checks or free browser checks for text and images | AI-generated and deepfake content detection for moderation pipelines | Developers adding AI media detection and moderation through an API |
| Text detection | Checks writing in the native app and online checker | Documentation describes AI-generated detection for image, video, text, and audio | No Sightengine is image-only; it doesn't detect AI-generated text |
| Image detection | Checks photos, synthetic images, and provenance clues in the app or online checker | Image and video AI-generated detection is listed | AI Image Detection is listed for detecting AI-generated images |
| Deepfake detection | Covers deepfake and synthetic-image checks as image detection | Deepfake detection is listed for image, video, and audio workflows | Deepfake Detection is listed for face swaps and AI manipulation |
| Metadata and provenance signals | Reads SynthID, C2PA, and IPTC signals in native and online image checks when a file carries them | Not publicly clear | C2PA Checker and EXIF & Metadata Viewer are listed |
| 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 | APIs return confidence scores | API model capabilities and operation counts are documented |
| Browser checker | Free online checker runs in any browser on Numen's private Mac server; submissions are deleted after processing | Free AI detector Chrome extension is listed | Not publicly clear |
| 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 | AI-generated and deepfake content detection APIs are documented | API documentation and API keys are listed |
| 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. | Pricing page lists free credits after adding a payment method | Free tier lists 2,000 operations per month with a 500 per day maximum |
| 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, billing, and analytics data; it does not specifically describe how content submitted to its detection APIs is collected or retained | Its policy covers subscriber-submitted data sent to the API for analysis, and its security page says Enterprise customers can request immediate deletion after processing; the default retention period on other plans is not stated |
| Main limitation | On-device privacy requires iPhone or Mac; browser checks run on Numen's private Mac server, not on-device | Enterprise/API-first workflow for high volume processing | API-first tool; paid plans meter operations |

Where Slop or Not Fits
Sightengine's permanent free plan never touches text, and Hive's free credits stay locked behind a payment method. Slop or Not checks text and images together, on-device, with no card and nothing to unlock first.
- 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.
