McKinsey’s internal AI tool “Lilli” is transforming consulting work, cutting the need for entry-level analysts and the industry will never be the same.
McKinsey & Company, one of the world’s most influential consulting firms, is making headlines by replacing junior consultant tasks with artificial intelligence. The firm’s proprietary AI assistant, Lilli, has already become an essential tool for over 75% of McKinsey employees and it’s just getting started.
Introduced in 2023 and named after Lillian Dombrowski, McKinsey’s first female hire, Lilli is changing how consultants work. From creating PowerPoint decks to drafting client proposals and researching market trends, this AI assistant is automating tasks traditionally handled by junior consultants.
“Do we need armies of business analysts creating PowerPoints? No, the technology could do that,” said Kate Smaje, McKinsey’s Global Head of Technology and AI.
Here are four important points from the article:
- McKinsey’s AI platform Lilli is now used by over 75% of its 43,000 employees to automate junior-level consulting tasks.
- Lilli helps consultants create presentations, draft proposals, and research industry trends using McKinsey’s internal knowledge base.
- Despite automation, McKinsey claims it won’t reduce junior hires but will shift them to more high-value work.
- AI adoption is accelerating across consulting firms, with Bain and BCG also deploying their own proprietary AI tools.
What Is McKinsey’s Lilli AI Platform?
Lilli is a secure, internal AI platform trained on more than 100,000 proprietary documents spanning nearly 100 years of McKinsey’s intellectual property. It safely handles confidential client data, unlike public tools like ChatGPT.
Consultants use Lilli to:
- Draft slide decks in seconds
- Align tone with the firm’s voice using “Tone of Voice”
- Research industry benchmarks
- Find internal experts
The average McKinsey consultant now queries Lilli 17 times a week, saving 30% of the time usually spent gathering information.
Is AI Replacing Junior Consultant Jobs?
While Lilli eliminates the need for repetitive entry-level work, McKinsey claims it’s not reducing headcount. Instead, the firm says junior analysts will focus on higher-value tasks. But many experts believe this is the beginning of a major shift in hiring.
A report by SignalFire shows that new graduates made up just 7% of big tech hires in 2024, down sharply from 2023 a sign that AI is reducing entry-level opportunities across industries.
McKinsey Isn’t Alone AI in Consulting Is Booming
Other consulting giants are also embracing AI:
- Boston Consulting Group uses Deckster for AI-powered slide editing.
- Bain & Company offers Sage, an OpenAI-based assistant for its teams.
Even outside consulting, AI is replacing traditional roles. IBM recently automated large parts of its HR department, redirecting resources to engineers and sales.
The Future of Consulting: Fewer Grads, Smarter Tools?
As tools like Lilli become smarter, the traditional consulting career path could be upended. Analysts once cut their teeth building slide decks and summarizing research tasks now being handled instantly by AI.
This shift could:
- Make entry into consulting more competitive
- Push firms to seek multi-skilled junior hires
- Lead to fewer entry-level roles and leaner teams
Final Thoughts: Adapt or Be Replaced?
AI is no longer a distant future it’s today’s reality. Whether you’re a student eyeing a consulting career or a firm leader planning future hires, the consulting world is changing fast. Tools like Lilli are not just assistants they’re redefining the role of the consultant.
The future of consulting lies in AI-human collaboration, but it may also mean fewer doors open for newcomers.
