PwC has successfully scaled generative AI across its enterprise using Microsoft Azure AI, creating a secure architecture for broad adoption and innovation. PwC's approach enables employees to access generative AI tools, enhancing productivity with proprietary solutions. Read this customer story to see how you can build a scalable and secure AI framework on Azure.
What is ChatPwC and how is it built on Microsoft Azure AI?
ChatPwC is PwC’s private Generative AI assistant, designed to help its people handle day‑to‑day work more efficiently while keeping client and firm data protected.
PwC built ChatPwC on Microsoft Azure AI with a few key components:
- **Azure OpenAI Service** – Provides the large language models that power natural language conversations and content generation.
- **Azure AI Document Intelligence** – Delivers text extraction and optical character recognition (OCR), so employees can pull structured insights from complex documents.
- **Azure AI Search with retrieval‑augmented generation (RAG)** – Adds semantic search and ranking so ChatPwC can ground answers in PwC’s own content and domain knowledge.
- **Azure Kubernetes Service (AKS)** – Orchestrates these services as APIs and integrates them with PwC’s proprietary plugin architecture.
From a security standpoint:
- All data ingested into ChatPwC is stored behind **PwC firewalls**.
- Data used in ChatPwC is **not used to train** the underlying large language models.
- PwC’s internal governance organizations provide quality assurance and oversight of how GenAI is deployed.
This combination lets PwC scale GenAI across the firm while keeping control over data, performance, and compliance.
How widely has ChatPwC and GenAI been adopted inside PwC?
PwC has seen broad, structured adoption of ChatPwC and other GenAI tools across its global workforce.
**ChatPwC adoption**

- Now used by **75,000 professionals in the United States** and another **125,000 employees globally**.
- In total, around **200,000 PwC employees** are using ChatPwC.
**Adoption journey**
PwC designed a four‑phase journey to help people build skills and confidence:

2. **See it** – Demonstrate real use cases and outcomes.
3. **Try it** – Encourage experimentation through pilots and guided sessions.
4. **Do it** – Embed GenAI into everyday work.
To support this, PwC:

- **GitHub Copilot** – Adopted by about **70% of relevant engineering staff**.
- **Microsoft Power Platform GenAI features** – Rolled out with targeted enablement.
Through the **My AI** upskilling initiative, PwC ran hands‑on events like “prompting parties,” helping drive **95% engagement** with My AI. During a Microsoft GenAI pilot:
- **88% of users** reported time savings.
