Introduction

If you're building agentic applications, the hardest question isn't "Can AI do this?" but rather "What should I build first?"

This chapter gives you 50 real-world use cases across six key domains—each with practical details to help you evaluate complexity, estimate build time, and understand the technical requirements.

Why Use Cases Matter for Builders

Most AI content falls into two traps:

1. Too vague: "AI can help with customer support!" (Okay, but how?)
2. Too specific: Hyper-niche examples that don't generalize

These 50 use cases hit the sweet spot: specific enough to be actionable, general enough to apply to your domain.

How to Evaluate Which to Build First

Not all use cases are created equal. Here's a framework for prioritization:

The Complexity/Impact Matrix

High Impact, Low Complexity → BUILD FIRST
- Quick wins that prove value
- Examples: Email classifier, meeting summarizer

High Impact, High Complexity → BUILD LATER
- Worth the effort, but requires infrastructure
- Examples: Multi-agent orchestration, personalized recommendation engines

Low Impact, Low Complexity → BUILD FOR LEARNING
- Great practice projects
- Examples: Simple chatbots, basic content generators

Low Impact, High Complexity → AVOID
- Not worth the investment

Evaluation Criteria

For each use case, consider:

• 🟢 Simple: Basic agent with 1-2 tools, minimal state management (1-3 days)
• 🟡 Moderate: Multiple tools, workflow orchestration, external integrations (1-2 weeks)
• 🔴 Complex: Multi-agent systems, advanced RAG, real-time processing (2-4+ weeks)

Impact factors:

• Time saved per week
• Revenue generated or protected
• User experience improvement
• Scalability potential

Technical factors:

• Available APIs and integrations
• Data quality and access
• Required infrastructure
• Team expertise
