Every book is a kingdom.
Walk it to the end.
Upload any book you already own. Readii turns it into a journey — three-minute passages, a map that fills in as you walk it, and Reggie, the robin who's read every book there is, keeping you company along the way. Get stuck on a word? Tap it for a quick gloss, whatever language you're reading in. You just read.

The book you already own
Upload an EPUB or TXT and start in a few minutes. Nobody has to turn it into a course first, and there's no word list to get through before you begin.
Three minutes at a time
A whole chapter is long, and long is where you put it down. Readii cuts each chapter into short pieces, about three minutes each. Finish one and today counts.
Look a word up without leaving the page
Tap any word in the text and its meaning appears. Keep it if you want, and it comes back to find you a few chapters later. Don't keep it, that's fine too.
Looking things up costs you nothingCome back next week, still pick it up
Forgotten where you were, or who's who? Reggie catches you up first. Character cards open one at a time as you reach them, and never spoil what's ahead.
Skip what you can't get through
Skipping takes nothing away and changes nothing. Come back for it whenever you feel like it. If a passage is hard, the passage is hard. It isn't you.
Skipping is freeWhich one can you read right now?
