Questions & Answers

As answered by people managing Codility and BuiltWritten.

What makes your product unique?

BuiltWritten's answer:

Voice DNA — the AI learns your personal writing style from samples you provide. Unlike generic AI writers, every chapter sounds like you. Plus it's the only tool that covers the entire pipeline from notes to KDP-ready export in one editor: writing, formatting, cover design, and export.

Why should a person choose your product over its competitors?

BuiltWritten's answer:

Sudowrite and Squibler generate text but don't format for KDP or design covers. Atticus and Vellum handle formatting but have zero AI writing. With Built&Written you don't need to stitch five tools together — one editor handles outline, AI co-writing, formatting, cover design, and PDF/EPUB export.

How would you describe the primary audience of your product?

BuiltWritten's answer:

Entrepreneurs, coaches, and consultants who want to publish a non-fiction book to build authority and generate leads — but don't have months to spend on the traditional writing and publishing process.

What's the story behind your product?

BuiltWritten's answer:

We kept seeing the same pattern: entrepreneurs had the expertise for a great book but got stuck in the production pipeline — bouncing between ChatGPT, Google Docs, Canva, and Kindle Create. Most quit before publishing. So we built one editor that handles everything from raw notes to a KDP-ready book.

Which are the primary technologies used for building your product?

BuiltWritten's answer:

Next.js, TypeScript, Supabase, PostgreSQL, and Vercel. The AI layer uses large language models for content generation and style matching.
