## What is IO 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.

FIVE CENTURIES OF THE CANON
Thousands of free public-domain classics, including hand-edited Standard Ebooks editions — Austen to Aurelius — beautifully typeset and presented like a magazine. A For You feed learns how you read, not just what, and points you to your next book.

BRING YOUR OWN BOOKS
Import your own DRM-free EPUBs — the open format used by Standard Ebooks and most independent publishers. (Books protected with DRM from other stores cannot be opened.) Save web articles to read later, too. Everything you add is yours to keep and read offline.

THE REST OF THE INSTRUMENT
• Cross-device sync — your place, saved passages, and library on every device
• Like the passages that matter, attach notes, and keep them in your Keepsake Box
• Reader-profile personalization that tunes the reading and the AI to you
• Sign in with Apple — delete your account and all your data anytime, in the app
• No ads. No clutter. Just reading.

IO+
Go further with IO+: unlimited AI personas, AI-powered search and recommendations, and sync across all your devices.

• IO+ Monthly or Annual
• Payment is charged to your Apple ID at confirmation of purchase.
• Subscriptions auto-renew unless turned off at least 24 hours before the end of the current period. Manage or cancel anytime in App Store settings.

다운 받아 보세요👍🏼

### 5/5 — GREAT app!

*2026-07-13*

This app has helped me read and understand on a whole new level, and the advanced AI technology has helped me interpret confusing passages as well. I’m now finding myself reading classics in my spare time over doomscrolling.  English is my second language and even though I can speak fluently, I occasionally stumble on big words and the AI translation tool is so accessible and helpful in these cases! I have also been exploring all of the various AI personas, and they create such an immersive reading space.

### 5/5 — New way of reading

*2026-07-12*

I’ve never seen reading app that changes the way of reading like this. The reading mode is clean and keeps me focused. AI doesn’t read on behalf of me but being a companion when I want to think deeper while reading.

### How often is IO reader updated?

The latest version of IO reader is 1.0.4, last updated on July 17, 2026. While specific update frequency isn't detailed, the recent update suggests ongoing development and support for the application.

## Version history (last 5 releases)

### 1.0.14 — 2026-08-25

Reading streaks now sync across your devices, subscription handling is more reliable, and assorted polish throughout.

### 1.0.12 — 2026-08-20

This update is about steadiness. Reels no longer freeze after a long stay in the background, the reader no longer sticks on its loading screen when an open is interrupted, and Listen Mode survives a phone call — it pauses for the call, then picks up where you were.

The app also holds less in memory while you read and listen, which older iPhones will feel. And For You, the daily shelf for IO+ readers, now picks from the whole catalog and says why each book made the cut.

### 1.0.11 — 2026-08-15

Standard Ebooks downloads land reliably now. The server sometimes handed us its "Your Download Has Started!" page instead of the book; we ask for the book directly.

Meanwhile the shelves keep growing: new classics have joined the curated library — more than five hundred books, with the whole of Project Gutenberg and Standard Ebooks a search away.

### 1.0.10 — 2026-08-12

Passages you keep now look the way they do in the book. In your keepsake box, verse breaks into lines instead of running together, italics and small caps survive, and a quotation with two paragraphs stays two paragraphs.

Small caps render in Reels as well — proper nouns in Standard Ebooks editions had been showing as ordinary text.

AI now runs on one model for everyone, so the model chooser is gone from the chat header and from Settings.

### 1.0.9 — 2026-08-09

릴스의 챕터 페이지가 책답게 열립니다. 챕터 제목이 더 큰 글자로 화면 가운데에 자리 잡아, 왼쪽 여백에 붙어 답답하던 문제가 사라졌습니다.

진행 바를 드래그하면 어디에 도착할지 미리 보입니다. 바 아래 표시줄에 해당 위치의 챕터와 정확한 진행률이 함께 표시되고, 위쪽 버튼을 가리지 않습니다.
