Hi everyone, I’m Casper, co-founder of First Book ai. After spending more than two years writing my own first book, I realized most business authors struggle not with ideas - but with time. That’s why we built First Book ai: to help anyone turn their expertise into a complete, professional book in hours instead of months. It’s now used by over 2,000 authors to create 10,000+ books for thought leadership, client growth, and teaching. The tool guides you step by step, from concept to a publish-ready draft—no writing background needed. Unlike generic AI tools, it’s built specifically for long-format business books and guided writing. If you’ve been meaning to write a book but never found the time, this is built exactly for that. // Casper
