If you're seeking a different Otto alternative, Storly.ai is worth a look. Storly.ai uses AI to generate questions for an interview that will then construct your life story in 5 minutes or less. It's got a talk-to-text interface so you can record personal or professional stories. It's designed for authors, businesspeople, and others, and it lets you control privacy so you can keep your stories private or share them.
Another option is Life Story. This AI-powered service, led by Lisa, will turn your answers to its questions into a personalized biography in a 250-page softcover book. You respond to questions by email, and the service transcribes and edits your answers into a single narrative. Life Story lets you customize the book with different covers and photos, and it promises to keep your data private, storing it securely. It offers a 45-day money-back guarantee and a pretty reasonable pricing structure.
