When to Use AI in Your Product (And When Not To)

AI isn't always the answer. Here's a framework for deciding when AI adds value and when simpler solutions work better.

The AI Hype Problem


Every product roadmap now includes "add AI" somewhere. But AI is a tool, not a strategy. Using it wrong wastes money and creates technical debt.


Here's how we evaluate whether AI is right for a feature.


The Decision Framework


Use AI When:


1. The problem is fuzzy

AI excels when inputs vary unpredictably. Good examples:

  • Natural language understanding
  • Image classification with many categories
  • Recommendation systems

  • 2. Rules would be endless

    If you'd need thousands of if-statements, AI might be simpler:

  • Spam detection
  • Fraud detection
  • Content moderation

  • 3. You have quality data

    AI needs data to learn. No data = no AI. Questions to ask:

  • Do you have 10,000+ examples?
  • Is the data labeled correctly?
  • Does it represent real-world distribution?

  • Don't Use AI When:


    1. Deterministic logic works

    If you can write the rules, do it:

  • Price calculations
  • Form validation
  • Workflow routing with clear criteria

  • 2. Explainability is required

    AI decisions are often black boxes. Avoid AI when:

  • Regulatory audits require explanations
  • Users need to understand why
  • Legal liability depends on reasoning

  • 3. You can't tolerate errors

    AI makes mistakes. All AI makes mistakes. If 95% accuracy isn't acceptable:

  • Financial calculations
  • Safety-critical systems
  • Compliance decisions

  • Real Examples


    Good AI Use Case: Document Classification


    A client had 50+ document types to route. Rules-based approach required constant maintenance as document formats changed. AI classifier achieved 98% accuracy and handles new variations automatically.


    Bad AI Use Case: Lead Scoring


    Another client wanted AI for lead scoring. But they only had 500 leads with outcomes. We built a simple rules-based scoring system instead. It works, it's explainable, and it can be tuned by sales without engineers.


    Implementation Principles


  • Start without AI: Build the feature with rules first
  • Measure the gap: Quantify where rules fail
  • Prototype quickly: Test AI on a subset before committing
  • Plan for errors: How will wrong predictions be handled?
  • Monitor forever: AI models degrade over time

  • The Bottom Line


    AI is powerful but not magic. Use it when the problem genuinely requires learning from data. Use rules when logic is clear. The best systems often combine both.
