Mnemonic is a global nonprofit organization that helps human rights defenders, journalists, researchers, and activists preserve and investigate digital evidence from war crimes, state violence, extremism, and online harm. The organization specializes in open source investigations, large scale video archiving, visual verification, and digital evidence preservation. Mnemonic has become one of the leading organizations in the field of human rights focused OSINT investigations and digital accountability work.
Mnemonic works with investigators and civil society organizations to document atrocities that are often removed from social media platforms or hidden through coordinated disinformation campaigns. Their tools and projects help preserve videos, images, metadata, and online records that may later become evidence in legal proceedings, investigative journalism projects, or public accountability efforts. Their work has been used in investigations connected to conflicts in Syria, Sudan, Ukraine, Gaza, and other global human rights crises.
One of the organization’s most important contributions is its focus on preserving vulnerable digital evidence before platforms delete it or algorithms bury it. For activists, journalists, resistance researchers, and independent investigators, Mnemonic provides valuable resources for understanding how digital evidence collection works in modern investigations. Their educational materials also help teach verification methods, ethical evidence handling, metadata preservation, and open source research practices.
Mnemonic is especially useful for researchers interested in OSINT methods, protest documentation, extremism monitoring, digital archiving, human rights investigations, and evidence preservation. The organization regularly publishes reports, case studies, technical explainers, and collaborative investigative projects that demonstrate how online evidence can be used responsibly and effectively.
