What's inside
Five features working on every page.
Grammar, explained in the line you're reading
When a sentence hides a construction worth knowing, a quiet Grammar row appears. Open it for a short, plain-language rule tied to that exact line — form, gist, an example from your book, and the one mistake to avoid. No separate grammar course to grind through.
- The construction is highlighted right in the text.
- Form, plain gist, an example from your book, a pitfall.
- Tied to CEFR level — never a separate curriculum.

The construction glows in the text; the “Grammar” row opens the rule behind it.

FAQ
Questions about the Reader
Can I read my own books?
Yes. Upload your own EPUB or FB2 and read it with the same tap-to-translate dictionary and in-context grammar as the built-in library. The sentence-by-sentence parallel translation is only on our library titles, though.
Can I read offline?
Yes. Download any book to your device and keep reading without a connection. Word taps and saved words queue locally and sync the moment you're back online.
Which file formats are supported?
EPUB and FB2 — the two most common open e-book formats. If your book is in another format, convert it to EPUB first with a free tool like Calibre.
Which languages can I read in?
English is the language you're learning. Your native (translation) side can be Russian, German, Spanish, French, Italian, Portuguese, or Chinese — Simplified or Traditional.
What level of English do I need to read books in the original?
You can start earlier than you think. With the tap-to-translate dictionary and the translation beside the text, simple classics work from about A2, and most originals feel comfortable from B1. Every book in the library shows its level (A1–C1), so it's easy to pick one that fits.
How do I choose my first book in English?
Take something short, a bit below your ceiling, and genuinely interesting — fables, children's stories, or short fiction make a great start. In the LangOrbit library every book is labeled by level, and the built-in dictionary keeps unknown words from stopping you.
Is the Reader free?
You can try it for free: the Reader has a free tier with no card and no sign-up required. Beyond that it's paid — the free tier is enough to see whether the Reader is for you.
What happens to the words I tap?
You can save them to your word list. To actually learn them, open the LangOrbit app: your saved words enter a spaced-repetition schedule that brings each one back right before you'd forget it. The Reader itself is built purely for comfortable reading, collecting new vocabulary, and exploring grammar.
