Executive summary
As internal audit functions try to keep up with growing demands, many have turned to GenAI. High-performing teams are even going beyond prompts to create AI agents that help them automate reviews and other tasks, combining human expertise with the speed and power of AI. Our 16 AI agents are practical examples of how internal auditors can embed agents into their audit lifecycle to reduce manual effort, improve workpaper quality and elevate insights for stakeholders.
The efficiency equation
Internal Auditors are consistently asked to do more with less.
They face pressure to expand their coverage, deepen their insights and improve stakeholder experiences while working with little or no increase in resources. Now, enterprise AI solutions such as Copilot are helping internal auditors combine human experience with artificial intelligence to improve scope, insight, impact and outcomes. The opportunities are immediate and important.
AI is already being embedded into everyday workflows. The following are 16 practical AI agents that internal audit practitioners can refine and deploy today. Each agent is designed to support both preparation and review, producing an audit-ready first draft that internal auditors can refine and finalize with their professional judgment.
16 AI agents
Note: Make sure that your AI agents have the appropriate governance for development, testing, training, security, data access and other processes. Revise and refine these and other AI agents, initially and over time, to ensure their ongoing effectiveness and compliance (see the tips section that follows this one).

Tips to create your own agents
Start with an agent or create your own. Either way, the key is to refine it until it provides the output you want. Here are some specific tips:
- Start with what you want
Not sure how to write a prompt? Start by entering what you want to accomplish, provide the inputs you have and ask the agent to generate a strong first-draft instruction. Then refine and reuse it. - The differentiator: preparation + review
Most teams use AI to draft. High-performing teams use AI agents to draft and self-review against audit criteria, reducing rework and improving defensibility. - Your output is only as good as your inputs
Before running an agent, assemble a minimal input pack: scope, criteria, process documentation, control descriptions and prior issues. Missing inputs increase rework. - Keep facts and fixes separate
Draft and confirm the observation (facts, evidence and criteria) first; develop recommendations second. This improves alignment and adoption. - Standardize agents like templates
Treat agents as reusable methodology assets: centrally owned, tested, version-controlled, and published for the whole team. Expect to improve or replace them as sophistication increases and technology advances. - Use AI to strengthen professional skepticism
Use the review step to challenge evidence sufficiency, criteria alignment and linkage (conclusion → procedure → evidence). - Start with three quick wins
If starting from zero: (1) PBC generation and validation, (2) RCM and control attributes, (3) observation drafting (facts-first). These show immediate ROI.
Why it matters
AI does not replace internal auditors; it helps them operate more efficiently, consistently and strategically.
Embed practical agents into your audit lifecycle to reduce manual effort, improve workpaper quality and elevate insights for stakeholders. Teams that standardize these agents and apply appropriate governance will be better positioned to meet evolving expectations and deliver greater value across the organization.
