Spec Coding is a specification-first approach:

• AI uses your specifications to generate code that precisely matches your vision
• Fewer iterations needed because AI understands the full context
• Better architecture and more maintainable code

To use Spec Coding, first complete your project specifications in the AI Co-Founder tab, then switch to Spec mode using the mode toggle in the chat input.

Capacity's natural language interface makes app creation simple:

• Just describe what you want to build in plain English

• The more specific you are, the better the results
