Powering some of the most innovative platforms worldwide

We outperform other solutions in client-led benchmarks

With 10 years of experience in Automated Moderation, we have built proprietary specialized models on the most difficult situations to match human-level accuracy. Advanced customization, fine-grained controls, and feedback loops with continuous improvement.

Sightengine has been key in powering our growth.

After extensively evaluating other solutions, we were extremely pleased by the accuracy of Sightengine's moderation models and the variety of situations they are able to correctly flag. Their models outperform other solutions and are simple and quick to integrate with. Aymeric Roffé

Instant analysis on 30+ criteria to assess nudity and suggestiveness in media

Reality is messy. Nudity is not a simple concept. There are tons of gray-area situations that each platform will need to handle differently. Sightengine helps you make sense of those and implement your own custom rules. To do so, our detection engine analyzes 30+ different concepts: context, clothing, action, poses, framing and more.

Combine concepts to create your own custom rules

Build advanced workflows that take into account the level and type of nudity, the type of image/video, the clothing involved, the action, the context, the framing and more.

Adapt and change your rules at any time. See changes take effect immediately.

Example 1
Flag bare male chests in specific situations. Allow bare chests in beach settings, at swimming pools and on statues.
Example 2
Allow female swimwear only in specific cases. Reject suggestive poses in swimwear, suggestive framings, and reject photos of children in swimwear or women posing at home in their bikini.
if bare chest detected then
if context is swimming pool or sea / lake then accept
else if slightly revealed chest and outdoors then accept
else if sculpture then accept
else reject

Moderate based on context as well as content

Adapt filters to the context and location of the image. Swimwear, bikinis and bare chests might be ok at the beach or near a swimming-pool, but could be a no-no in other settings.

You get to determine if the context should be taken into account with your own custom rules.

Fine-grained limits so you can define exactly what you want to filter

Sightengine gives you fine-grained controls over each concept, allowing you to set custom limits that are adapted to your audience.

Bare male chests and torsos
3 different levels of suggestiveness depending on which parts of the torso are visible: slightly revealing, revealing or very revealing.
Cleavages and necklines
3 different levels of nudity depending on which parts of the neckline and breasts are visible: revealing, very revealing or erotica.

Automatically set stricter limits on content featuring young users

Adapt filters to the subject's estimated age range. Reject suggestive poses or swimwear pics featuring younger users.

Age is estimated based on both body and facial features. This helps achieve better results and makes it possible to filter images even when the subject's face is hidden or invisible.

REACH OUT

Differentiate based on the subject's estimated age

Adult in swimwear

Detected age above 18 yrs

Differentiate between real-life, drawings and art

Nudity can be present in real-life images or videos, in animated ones, or in artistic pieces such as in sculptures or paintings. You might want to handle those situations differently. With Sightengine, you can.
