How to Choose

Not all ideas are equal for your situation. Consider:

Your expertise - Build in domains you understand. AI handles execution, but you need to know what good looks like.

Market size - Niche is good, but ensure enough potential customers exist to sustain a business.

Willingness to pay - B2B and productivity tools monetize easier than consumer apps. People pay to make money or save time.

Competition - Some categories are crowded. Look for underserved niches within broader categories.

Technical feasibility - AI capabilities have limits. Test your core use case with current APIs before committing.

Building with AI

Most of these apps follow a pattern:

  1. Input - User provides data (text, images, files)
  2. Process - AI analyzes, generates, or transforms
  3. Output - Structured results users can act on
  4. Iterate - User feedback improves results

The technical implementation often takes days, not months. The hard part is finding users, understanding their workflows, and building something they’ll pay for.

Pick one idea. Build the smallest version that tests the core value. Ship it. Learn. Iterate.

The best app idea is the one you actually build.
