Chat Moderation Solutions

Healthy Community

Users exposed to unmoderated toxicity are three times more likely to disengage from an online community. But only a small percentage of users are toxic, why treat all their messages the same? The problem isn’t something bad being said once, it's about a user repeatedly engaging in toxic behavior that disrupts a healthy community.

Identify Your Toxic Users

Context is King

Sift has innovated a better way to manage unwanted toxic behavior and to reward positive behavior by evaluating a user's reputation and understanding the risk of a message in proper context. This creates a positive experience for your users by increasing user engagement, ensuring safety, and building trust in your community.

Reward Positive Behaviour

Simple to Install and Use

Sift provides the most advanced functionality in the industry, all wrapped up in a simple HTTPS call. You just send your UGC and Sift filters it through your policies for that page, channel, or user. It will return “true” if the content passes or “false” if it doesn’t. It will then generate any additional parameters you have set, such as whether to h#sh out certain words, display warning messages, and so on. Sift’s backend is loaded with webhooks that can make calls to your server or generate a human review.

Expanded Language Support

Behind Sift are full-time native speakers for each of its growing set of supported languages. In addition, we have developed a means to quickly identify core toxic-language patterns in additional languages to rapidly build a contextual database of problematic communications. Once we do all that work, we then tune it to your environment. Sift uses multiple algorithms in both natural and unnatural language to perform quality control on our list to form an effective defense against toxic users trying to bypass your system.
