10 Mistakes People Make with AI Builders

9 min readJanuary 12, 2026By Spawned Team

Common pitfalls and how to avoid them. Learn from what trips up most first-time users.

1. Starting Too Complex

The mistake: Trying to build a full product in one prompt.

The fix: Start with the simplest possible version. Add features one at a time.

2. Vague Descriptions

The mistake: "Make it modern and clean"

The fix: "White background, Inter font, subtle gray borders, plenty of whitespace, rounded corners on cards"

3. Ignoring the Preview

The mistake: Writing long prompts without checking results.

The fix: Look at the preview after each change. Course-correct early.

4. Not Testing on Mobile

The mistake: Only looking at desktop view.

The fix: Switch to mobile preview regularly. Half your users are on phones.

5. Forgetting Edge Cases

The mistake: Only testing the happy path.

The fix: Ask "what happens if..." What if the list is empty? What if the name is really long? What if they're not logged in?

6. Over-Specifying Implementation

The mistake: "Use a useState hook with a reducer pattern for the form state"

The fix: Describe the behavior, not the code. "The form should validate on submit and show errors under each field"

7. Not Saving Versions

The mistake: Making changes without being able to go back.

The fix: Export to GitHub regularly. Use Spawned's version history. Before big changes, save a snapshot.

8. Skipping the Basics

The mistake: Adding fancy features before core functionality works.

The fix: Make sure users can complete the primary task before adding dark mode, animations, and extras.

9. Copy-Pasting Generic Content

The mistake: Launching with "Lorem ipsum" placeholder text.

The fix: Write real copy. Or ask the AI to generate realistic content for your specific use case.

10. Building in Isolation

The mistake: Spending weeks building before showing anyone.

The fix: Share early and often. Real user feedback is worth more than your assumptions.
