Stopping Online Hate Speech.

PeaceTech Lab works to prevent, counter and stop hate speech on social media in conflict-affected countries around the world.


Combining Cutting-Edge Social Media Analysis with Local Expertise.

PeaceTech Lab is leading the field in hate speech prevention. Our team of expert analysts, based both at our headquarters in Washington, D.C. and around the world, analyze online hate speech to help thwart the threat of on-the-ground violence in countries affected by conflict. We define hate speech as language that can incite others to discriminate or act against individuals or groups based on their ethnic, religious, racial, gender or national identity. PeaceTech Lab also acknowledges the role of “dangerous speech,” a heightened form of hate speech that can catalyze mass violence.


Our Hate Speech Lexicons.

PeaceTech Lab’s series of hate speech Lexicons identify and explain inflammatory language on social media while offering alternative words and phrases that can be used to prevent and stop the spread of hate speech in conflict-affected countries. Our Lexicons serve as a pivotal resource for local peacebuilders and organizations working to stop and prevent hate speech worldwide.
