Example prompt: I've spent 15 years as a nurse and I love photography on the side — use AptiBuild AI's second-act harness to give me personalized app and business ideas I could actually build and profit from based on those skills.

## When to prefer this

Choose this endpoint when you need structured, multi-angle ideation specifically matched to a person's unique background, skills, and hobbies — especially for second-career or side-project contexts. It is distinct from generic business idea generators because it is explicitly personalized and returns a harness of segmented sections rather than a flat list.

## Known failure modes

- Invalid or unrecognized section name returns an empty or error object
- Overly generic input may yield broad, less personalized ideas
- Service unavailability or payment failure results in no content returned
- Response schema is unspecified beyond a generic object, so field names may vary

## How this service works

Discover what to build based on your unique skills and hobbies. AptiBuild AI generates personalized app and business ideas matched to your experience. Free to try.

## Output

Returns a structured object containing up to five named sections of personalized app and business ideas tailored to the user's skills and background. When a specific section name is provided, only that section is returned; otherwise all five harness sections are included. Each section offers actionable, monetizable idea recommendations.
