IO reader vs Parallèle Reader

Read deeper. Think sharper. Depth is becoming rare. The modern screen is built for speed, brevity, and interruption — training us to scan instead of study. IO is built for the opposite: a calm, focused place to read the books that reward attention, with an AI that challenges you to think rather than thinking for you. A NEW WAY TO READ IO strips the page down to a single unit of thought. • Reel — read one paragraph at a time, in a clean vertical flow. • Cards — move through a chapter one sentence at a time, for close, deliberate reading. No wall of text, no progress anxiety — just you and the words in front of you, for as long as they deserve. AN AI THAT ASKS MORE OF YOU Tap any passage and choose a companion. IO's personas don't summarize the book — they make you a sharper reader of it: • Critical Thinker — surfaces hidden assumptions and second-order implications • Interpreter — rewrites a difficult passage to match how you read • Questioner — asks escalating, Socratic questions • Historian · Philosopher · Psychologist · Rhetorician — read for context, ideas, motive, and craft • Vocab Coach · Quiz Master · Note-Taker · Futurist — for retention and study Twelve personas in all, each built to leave you sharper than the page found you. And the Translator carries any passage into ten languages without flattening its meaning.

Heritage and bilingual readers — move freely between both your languages on every page. Anyone after a book that was never translated for sale — read the original with a translation alongside. HOW IT WORKS Open one of the included classics, or import your own EPUB, PDF, or text file. In split screen, the original and a clean translation appear side by side, page by page — on your device with Apple Translate, or through your own DeepL key. Long-press a word or passage to look it up, highlight it, add a note, or save it to your vocabulary. Prefer to test yourself? Hide the translation and reveal it with a tap.
