How this comparison was made

Where Detector24 and Sightengine differ

Sightengine, 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.

  • Edited images: a score, or a model of their own

    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

  • Text and documents

    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

  • An API, or a workflow around it

    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

  • Published monthly plans on both sides

    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 vs Detector24, side by side

Sightengine and Detector24 by Bynn compared on images, deepfakes, video, voice and music, liveness, data location and retention, security and pricing, from Sightengine's public materials read on 17 October 2026 and Bynn's own pages.
SightengineDetector24
What it isAI 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.12Detector24, 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 imagesFlags 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.34Image-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 videoThe 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.56Image deepfake detection and video deepfake detection, among 27 image and 6 video entries in the published catalogue.19
Voice and musicAn 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.78Voice deepfake detection and AI-generated music detection, among the 3 audio entries in the published catalogue.19
Liveness and provenanceA 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.910Face liveness and document liveness are in the Detector24 catalogue; identity verification with liveness is part of ZOREAL Verify.1922
Data location and retentionBy 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.1315Deployment 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 statedSightengine 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.111218ISO/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
PricingFree: 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.1617From $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

Where Detector24 and Sightengine hold the same bar

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.

Choosing between Sightengine and Detector24

Both have real strengths. These are the situations each one's public materials point to.

Sightengine may fit you if

  • You want a self-serve plan with a published monthly price and a permanent free tier
  • You want per-generator scores for images and voice
  • You want passive face liveness on the same API keys as your moderation
  • You want processing pinned to the EU or North America under a French-law contract

Detector24 may fit you if

  • You need AI-edited regions in genuine photos detected by a model of their own
  • You need AI-generated text and fraud text detection in the same catalogue
  • You need document tampering and document liveness models as well as media models
  • Your checks sit inside document fraud or insurance claims workflows
