A few practical questions

What makes Colexi different from a normal reader app?

Colexi combines level-friendly reading, translations, narration, grammar support, flashcards, writing, and speaking practice around the same source material.

Can I try books before subscribing?

Yes. Guests can preview part of public books, and free accounts can start with a limited allowance before choosing a paid plan.

Does Colexi only work with books?

No. Books are the clearest reading experience, but you can also study YouTube videos, daily news, imported articles, class lessons, diary writing, flashcards, and speaking practice.

Can I read and listen at the same time?

Yes. The book reader supports narration by section, so you can listen while following the text and move between reading levels when you need more support.

Why not just use a chatbot?

Colexi keeps your study work organized around the source: the book page, article, transcript, or lesson you are learning from. That makes the explanations, flashcards, writing, and speaking practice easier to revisit.

One app. Every language.

Start with a book page, a news article, or a video. Let Colexi turn it into reading, listening, and practice.
