# McKinsey Lilli

McKinsey & Company's proprietary AI assistant / knowledge copilot. According to the source, it is used by **over 72% of McKinsey's workforce** and has **reduced research and synthesis time by ~30%.** Primary evidence for [[claim-ai-improves-speed-and-quality]].

**Enrichment note:** open sources describe firm-wide copilots (Lilli, Sage, etc.) aimed at reducing research/synthesis time and making institutional knowledge instantly searchable, but do not independently confirm the precise internal 72%/30% figures.
