Comprehensible input, on tap
Read and listen to real language that sits just above your level, with translation, narration, and explanations the moment something gets hard.
AI-powered reading and listening
Break through the intermediate plateau with real reading, audio, and AI.
Read level-friendly books, listen line by line, and turn every article, video, lesson, or speech into practice that matches your level.
Built for the intermediate plateau
Get over the intermediate hump
Beginners are spoiled for choice. Then progress stalls: real books, articles, and videos feel too hard, beginner apps feel too easy, and most tools quietly stop being useful. Colexi is built for exactly that gap.
You move forward by understanding a lot of language just above your current level. Colexi surrounds you with comprehensible input you can actually follow, then keeps support one tap away so you never have to stop and look elsewhere.
Always just hard enough
Move between reading levels mid-page and pull any book, article, or video toward a level you can actually follow without losing the meaning.
Input that turns into output
The reading and listening you do becomes flashcards, grammar, writing feedback, and speaking practice, so understanding turns into real production.

FAQ
A few practical questions
Who is Colexi for?
Colexi is built for intermediate learners stuck on the plateau between beginner courses and native material. If you can already read and listen a little but real content still feels just out of reach, the level-friendly sources and instant support are designed to pull you across that gap.
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.
Make the jump over the plateau today.
Start with a book, an article, or a video, and turn the content you can understand into the practice that finally moves you forward.
