Expertise
Index is a not-for-profit investigative NGO based in Paris. We investigate and publish expert reports on alleged acts of violence, violations of fundamental freedoms, and human rights abuses.
Bringing together a network of independent journalists, researchers, visual artists, architects, engineers, and lawyers, Index specializes in open source investigation, audiovisual analysis, and 3D digital reconstruction.
Mission
Index is firmly committed to the pursuit of truth and justice. The purpose of our action is to help establish the facts in cases where their public disclosure is hindered by interests of power.
Our investigations follow multi-year themes that address urgent matters of public interest. Since 2020, we have focused on “Police/Justice,” producing independent counter-investigations into cases of police violence in France. In 2025, we expanded our scope to include themes such as “Border Violence” and “French Overseas Territories.”
Our field of action is public above all. Often published in partnership with other news media, our investigations and reports are regularly used in the legal proceedings on relevant cases.
Through workshops and training programs with NGOs, universities, and citizens’ collectives, we help disseminate the tools and methods of open source investigation across civil society.
Network
Index was created as an autonomous extension of the Forensic Architecture research agency, to which it remains closely linked through its team and its methods.
Along with a dozen other independent investigative organisations around the world, INDEX is a member of the international network Investigative Commons.
Index is also a member of the Syndicat de la Presse Indépendante d’Information en Ligne (SPIIL).
