Questions & Answers

As answered by people managing FBReader and Calice.app.

What makes your product unique?

Calice.app's answer:

It keeps all your books in one place, paper and ebooks, and remembers what you've read and where you stopped. Read on your phone, tablet or computer, set reading goals and streaks, share your shelf with friends if you want, and get recommendations based on what you actually liked. It also has an optional AI assistant that has your whole book in context, not just search snippets: ask it about the plot or a character and it highlights the exact passage it is talking about. Private by default and hosted in the EU.

Why should a person choose your product over its competitors?

Calice.app's answer:

Most book apps only track titles, and most ebook apps only open files. Calice does both: a library, a reader and a reading log in one app, with no ads and with your data kept private. It also has an optional AI assistant that has read the whole book and points to the passage it means. Free for tracking physical books and your first 50 ebooks.

How would you describe the primary audience of your product?

Calice.app's answer:

Anyone who reads and wants one place for it: people moving away from Goodreads, ebook readers who want their books on every device, and anyone who likes setting reading goals. If you use Calibre, you can import your whole library.

Which are the primary technologies used for building your product?

Calice.app's answer:

React, Vite and Tailwind CSS on the frontend, a Flask API with PostgreSQL and Redis on the backend, installable as a PWA.
