We launched the nonprofit project Dosimeter. A dosimeter is a device that measures radiation; it became famous after the Chernobyl disaster

Dosimeter is a team of three people, based in Berlin. We monitor disinformation in AI assistants.

AI Disinformation Benchmark, updated 16 October 2026: the share of responses that cited Kremlin-linked sources or repeated pro-Kremlin false claims. DeepSeek 29.2%, Perplexity 20.7%, Grok 19.1%, Meta AI 16.8%, Microsoft Copilot 14.2%, Claude 12.0%, Mistral Vibe 8.7%, Gemini 6.2%, Google AI Overviews 3.0%, ChatGPT 2.5%

The benchmark includes 15 datasets, 20,908 processed sources in total (manually verified)1.

Most of the data comes from our own measurements; the rest comes from respected colleagues: Harvard Kennedy School Misinformation Review2, the Institute for Strategic Dialogue (ISD)3, NewsGuard4, Detector Media from Ukraine5 and others.

Save the link to the benchmark: dosimeteraudit.org/benchmark - it will come in handy as evidence in a debate.
