What each product offers, as listed by its team.

Sightengine 5 features
ShadowGuard 6 features
  • Comprehensive Image Moderation
    Sightengine offers a wide range of image moderation features that can detect nudity, offensive content, and unwanted objects. This makes it suitable for various platforms that require content filtering.
  • Ease of Integration
    The platform provides well-documented APIs and SDKs for easy integration into existing systems, supporting languages like Python, PHP, Ruby, and more.
  • Real-time Processing
    Sightengine is capable of processing images in real time, which is essential for applications requiring quick responses, such as live streaming moderation.
  • Multi-platform Support
    The service can be used across various platforms, including web and mobile applications, allowing flexibility in deployment.
  • High Customizability
    Users can adjust the sensitivity and settings to better fit their specific moderation needs, providing a tailored solution.

Possible disadvantages

  • Limited Free Tier
    The free tier is often not sufficient for larger applications, which may incur higher costs as usage increases.
  • False Positives
    There can be instances of false positives where non-offensive content is flagged, requiring manual review.
  • Privacy Concerns
    As with any content moderation service, there may be privacy considerations, especially regarding image data handling and storage.
  • Dependency on Network Connection
    As a cloud-based service, Sightengine requires a stable internet connection, which might not be ideal for all environments.
  • Learning Curve
    Even though the API documentation is comprehensive, there can still be a learning curve for developers who are not familiar with integrating third-party services.
  • Frame-by-frame video scanning
    Computer-vision analysis of every second of video, flagging nudity/suggestive content, weapons, alcohol, and drug-related visual signals.
  • Timestamped findings
    Each flagged moment comes with its exact timestamp, so you know precisely what to trim instead of guessing.
  • Cross-platform risk signals
    One scan checks separate risk thresholds for TikTok, Instagram Reels, and YouTube Shorts simultaneously.
  • No social account required
    Upload the raw video file directly — no TikTok/Instagram/YouTube login or account connection.
  • Automatic file deletion
    Uploaded videos are auto-deleted within 60 minutes after processing; never used for AI training.
  • Pay-per-scan credits
    No subscription — buy a credit pack and use scans whenever needed; credits never expire.

Questions & Answers

As answered by people managing Sightengine and ShadowGuard.

What makes your product unique?

ShadowGuard's answer:

Most competitors either require connecting your social media account to run a check, or give a vague verdict with no real computer vision behind it. ShadowGuard does neither — it's an independent, no-login pre-publish scan that flags the exact timestamped moment carrying risk, scored against TikTok, Instagram Reels, and YouTube Shorts thresholds at once.

Why should a person choose your product over its competitors?

ShadowGuard's answer:

Generic moderation APIs like Sightengine or Amazon Rekognition are built for developers to integrate into their own platforms — you need an API key and code. ShadowGuard is built for the individual creator: drag, drop, and get a plain-language, timestamped report in under a minute, no integration required.

How would you describe the primary audience of your product?

ShadowGuard's answer:

Individual content creators, agencies, and small teams posting short-form video to TikTok, Instagram Reels, or YouTube Shorts who want a quick sanity check before publishing.

Which are the primary technologies used for building your product?

ShadowGuard's answer:

React 19, Vite, Supabase (PostgreSQL, Auth, Edge Functions), and Sightengine's computer-vision API for frame analysis.

What's the story behind your product?

ShadowGuard's answer:

ShadowGuard started from a simple observation: social media moderation is no longer human. Today, it’s driven by ruthless, automated AI systems scanning every frame, OCR text, and audio track.

We saw creators and brands constantly playing a guessing game. They were getting their accounts restricted over false positives or minor policy triggers, completely flying blind. Relying on post-publish analytics felt like checking your parachute after you've already hit the ground.

We built ShadowGuard to level the playing field. It acts as an independent pre-publish diagnostic tool. By using advanced AI to scan video frames and visual signals, we allow creators to see what the algorithms see. We intentionally designed it without OAuth or account linking to ensure complete privacy. ShadowGuard is the tool we wished existed before hitting 'Publish'.
