How this comparison was madeSightengine, operated by Kozelo SAS in Paris, sells AI image, video, voice and music detection, deepfake detection and face liveness through the same API as its content moderation models, with Free, Starter and Pro plans published. Detector24 by Bynn brings specialist detection models to images, video, audio and text, answering generation and editing as separate questions. This page sets the detection side of Sightengine beside Detector24.
Sightengine says its AI image model covers fully AI-generated and AI-edited images, scored at image level; localisation of edited regions is not stated. Detector24 treats a fully generated image (Trinity) and an AI-edited region in a genuine photo as separate questions, with separate models.419
AI-generated text detection is not stated in Sightengine's public materials we reviewed, and fake IDs appear as a use case rather than a dedicated document model. Detector24's catalogue includes AI-generated text, fraud text, document tampering and document liveness.319
Sightengine is a hosted API with a web interface. Detector24's signals also sit inside Bynn's document fraud and insurance claims workflows, beside document forensics in ZOREAL Verify and agentic fraud reasoning.1922
Sightengine publishes a free tier and monthly Starter and Pro plans, with AI image and deepfake detection counted as 5 operations per image. Detector24 publishes its prices on detector24.ai: from $99 a month, monthly minimum commitment (Core plan), with a free tier.161719
| Sightengine | Detector24 | |
|---|---|---|
| What it is | AI content detection, deepfake detection and content moderation APIs, owned and operated by Kozelo SAS, a French company headquartered in Paris; its terms are governed by French law.12 | Detector24, Bynn's specialist detection models for images, video, audio and text: AI-generated images, image forgery, deepfakes and moderation, one question per model.19 |
| AI images | Flags AI-generated images, deepfakes and AI manipulations; covers fully generated and AI-edited images at image level, with a global AI probability and a score per supported generator; uses pixel content only, ignoring metadata, C2PA and watermarks. New generators are typically added within a few weeks, with lower accuracy in that window.34 | Image-authenticity models treat generation and editing as separate questions: fully AI-generated images detected from the pixels without relying on watermarks, localized edits within a genuine photo, face swaps in images and video, and synthesized voices in audio.21 |
| Deepfakes and video | The deepfake model scores the two most prominent faces and is optimised for identity-level manipulations such as face swaps; AI video detection returns frame-level scores at a configurable interval.56 | Image deepfake detection and video deepfake detection, among 27 image and 6 video entries in the published catalogue.19 |
| Voice and music | An AI voice detector covering 55 generators, including ElevenLabs, OpenAI, PlayHT and Resemble, scoring AI generation and AI processing as separate signals; AI-generated music detection based on the audio.78 | Voice deepfake detection and AI-generated music detection, among the 3 audio entries in the published catalogue.19 |
| Liveness and provenance | A passive face liveness check from a single selfie with no user challenge; a C2PA checker that reads an image's Content Credentials in the browser.910 | Face liveness and document liveness are in the Detector24 catalogue; identity verification with liveness is part of ZOREAL Verify.1922 |
| Data location and retention | By default requests may be processed in the EU, Canada or the US; Enterprise plans can keep data in one region, EU or North America. Images, video and audio are deleted after processing by default, with listed exceptions; the DPA includes Standard Contractual Clauses.1315 | Deployment environments are agreed for each engagement, around your requirements for data location, security and scale. Under Bynn's Data Processing Addendum, customer personal data is encrypted in transit over public networks and at rest, kept for the period you set or the order form provides, then deleted.2024 |
| Security stated | Sightengine states its data-centre partners are ISO 27001, SOC 2 and PCI DSS compliant; a certification held by Sightengine itself is not stated. SAML single sign-on and SLAs on Enterprise plans.111218 | ISO/IEC 27001:2022 certified by an accredited certification body, and a SOC 2 report from an independent auditor, monitored continuously, per Bynn's Trust Center and Data Processing Addendum. Controls are mapped to ISO/IEC 42001:2023: compliant, not certified.2324 |
| Pricing | Free: 2,000 operations a month, max 500 a day, no time limit. Starter: $29 a month for 10,000 operations, plus $0.002 per additional operation. Pro: $99 a month for 40,000 operations, plus $0.002 per additional operation. AI-generated media and deepfake detection count as 5 operations per image (times frames for video); speech and music as 1 operation per 10-second chunk.1617 | From $99 a month, monthly minimum commitment (Core plan), as detector24.ai publishes it, with a free tier; larger volumes are priced with the Detector24 team.19 |
Both detect AI-generated images, face-swap deepfakes, AI-generated video, synthetic voice and AI-generated music from the media itself, without relying on watermarks or metadata.
Both offer content moderation models from the same vendor as detection, and both name fraud uses, such as fake identity documents in onboarding, next to trust and safety.
Both return confidence scores per class through an API, for a reviewer or a system to act on.
Both have real strengths. These are the situations each one's public materials point to.
