Questions & Answers

As answered by people managing Open Library and Capitula.

Who are some of the biggest customers of your product?

Capitula's answer:

  • Individual readers and students
  • Book clubs and reading groups
  • Lifelong learners who listen with captions

What makes your product unique?

Capitula's answer:

Capitula keeps the argument of a classic instead of flattening it into bullet points. Every chapter is a short animated explainer with narration and word-by-word captions. The first chapter of every book is free, so you can judge the method before paying.

Why should a person choose your product over its competitors?

Capitula's answer:

Most summary apps compress contemporary bestsellers into 10-minute text. Capitula does the opposite: public-domain classics, one chapter at a time, as short animated videos you can read or listen to. No ads, no feed, no gamification.

How would you describe the primary audience of your product?

Capitula's answer:

Readers who want to understand classics but keep bouncing off them: students, book-club members, lifelong learners, and people who prefer listening with captions.

What's the story behind your product?

Capitula's answer:

Built by an independent developer in Hong Kong who kept quitting classics at chapter three. Capitula turns each chapter into a few-minute explainer so the argument lands before attention runs out. All texts are public domain; animation, narration and captions are original.

Which are the primary technologies used for building your product?

Capitula's answer:

React Native / Expo for the iPhone app; a Next.js web reader; TypeScript across the stack; an in-house animation and word-by-word caption pipeline.
