Proactive AI
Content Moderation

We act before the damage is done

By detecting and reducing online abuse you can ensure users’
safety and positive experience on your platform, which in turn lowers churn while increasing retention and compliance with regulations. Samurai utilizes a proactive approach to user protection and harm prevention, rather than acting reactively after the damage has already been done.

Samurai uses large language models and symbolic reasoning to detect cyberviolence in real-time, achieving even a 10x lower false positive rate than the competition. You can fully automate your moderation or use our AI to complement your current moderation stack, enabling you to stay on top of the constantly evolving landscape of online abuse and regulations.

Developing AI system that meets the goals of the National Strategy for Preventing Veteran Suicide

Suicide rates have been historically high among Veterans, with the estimated risk being 57% higher than that of the general population. In order to investigate the suicidal tendencies among this group, we collected over 41,000 posts from VA Disability Claims Community Forums –

Keeping schools and online learning safe by monitoring spaces and 1:1 chats to detect hostile or inappropriate conversations.

The purpose of Samurai is to detect and prevent violence, making it an essential asset for educational institutions that use platforms such as Webex for remote learning and communication.

Moreover, it has a positive impact on the schools’ reputation. By showcasing a reduced incidence of aggressive behavior, institutions can attract parents; preference and potentially  enhance students’ performance in international educational rankings.

Keeping a top gaming community safe from toxicity and cyberbullying by identifying 30% more cases of community guidelines violations

● Over 130 violations of Community Guidelines were detected by Samurai Guardian each day

● 30% more Community Guideline violations were detected by Samurai Guardian and would be automatically removed when compared to human moderators.

● Less than 3% of Community Guideline violations were removed by moderators without being detected by Samurai Guardian.

Samurai’s Username Moderation detected over 12000 toxic usernames since the launch of a new game title during the game’s first months on the market

Over 3 months we processed over 340,000 usernames coming from Freedom Games. Some of them contained two or more identical usernames. After removing them, circa 270,000 unique usernames remained, out of which circa 12,000 were detected as toxic. It means that 4.27% of all username attempts were blocked because of violating the community standards.

Our data-based analysis shows that we successfully detected 88.8% of all toxic usernames (recall) with a precision of 99.22%.

Conducting counter-speech interventions powered by AI to reduce toxicity and community violations on Reddit

The main objective of our experiment was to test whether the level of cyberviolence on Reddit can be significantly decreased by community-driven, counter-speech interventions conducted by users in partnership with Artificial Intelligence.

Preparing a toxicity analysis of the official Discord communities for two adult games and preparing a bot for autonomous proactive moderation adapted to these adult communities.

Even if your game does not have a huge community focused on Discord, or you have a community that allows a lot of content that is not allowed on other servers – Samurai can help you. Thanks to toxicity verification and automatic moderation, you can effectively increase player retention and satisfaction when playing the game.

Bringing real-time counterspeech to the darkest corners of the web in order to evaluate students after completing the online course

Samurai Labs together with INACH created an exercise for the participants of a counter speech course in which AI delivered cases of hate speech in real-time on 4 chan with a high precision. Thanks to its ability to scan millions of conversations within seconds, the most important needs of the course were addressed and the following value was created:

  • The possibility of evaluating the knowledge of trainees on real cases, straight after completing the course
  • Enabling people to test themselves and make real impact in the digital world with the acquired knowledge
  • The ability to positively model discussions on the web without the need to manually search for hate speech threads, saving time and hussle

AI Monitoring and Preventing Anti-Immigrant Hate on Social Media After Brexit Call

Samurai was engaged to develop AI models and analyze posts on Twitter and YouTube to detect violent speech acts against Poles. At the latter stage of the project Samurai’s data aim to power up HateLab custom dashboard for better measuring violence before and after Brexit, alerting authorities to trends and immediate threats.

Reducing personal attacks and cultivating healthier communities with autonomous counterspeech on Reddit

After analyzing the data, it turned out that without the help of penalties and bans, James reduced the subreddit’s aggression level by 19%. Moreover, the antisocial activity of those who received the interventions decreased in other Reddit groups as well.

There is reason to suspect that the interventions had a positive impact on overall user behavior rather than just motivating the audience to find another place to attack others.

Autonomous removal of offensive content from communities without exposing moderators to this stressful material and creating healthier and more positive communities.

Samurai Labs and Khoros faced the challenge of solving the issue and creating a system that would protect not only community’s users from harmful content, but also take care of the mental health of moderators who are most exposed.

cooperation with us

Overcoming hate speech is one of the greatest challenges in the modern world. However, the knowledge of psychologists and sociologists is not sufficient to effectively confront it. We often feel helpless when we see the flood of online hate. The actions of Samurai Labs restore hope that we can do something. When we combine scientists’ knowledge of how to change human behavior with sophisticated AI, we can not only interpret reality – but also change it. Change the behavior of specific haters who destroy our public life.

Samurai Labs’ innovative approach has proved to be very accurate
in detecting cyberbullying and internet aggression. The technology that they are developing will form an important part of our Online Dashboard.

Matthew Williams

Director, HateLab

Samurai Labs developed an AI driven platform for us that gives the basis of the final exercise our trainees need to finish to receive their certificates. This platform links our trainees completely anonymously to real life instances of cyber hate where they can directly practice what they have just learnt in a safe and practical manner.

Samurai’s Unique Approach:
LLMs + Symbolic Reasoning

In contrast to bare deep learning or bare symbolic systems, we harness a neuro-symbolic approach to AI, which takes the best from both worlds. Combining large language models (LLMs) and symbolic reasoning imbued with the knowledge of domain experts allows us to achieve exceptional precision enabling proactive moderation, and allows you to follow and understand the specific reasoning behind each decision it makes. 

When cyberviolence is detected, it can act immediately, step in on its own, or even alert moderators before any harm is done. This approach makes a huge difference compared to the old keyword detection methods and it’s much faster and more accurate than manual moderation.

The technology created by Samurai Labs is protected by 6 patents granted by the United States Patent Office.

Samurai saves lives with One Life Project

The goal of the One Life Project is to prevent suicidal behaviors through a network of support for people in crisis, whom we are
reaching using neuro-symbolic algorithms, analyzing millions of online conversations, and utilizing the experience of suicidologists and psychologists. So far, we provided help to over 25,000 users in crisis on Reddit, reaching out to them with supportive intervention.
