IO reader · For journalists
Press kit.
The story in three sentences
Every AI reading product on the market promises to read for you; IO reader is built to refuse. It pairs the public-domain canon with AI personas that challenge the reader — arguing with passages, building interpretations, demanding better translations — inside an interface designed for sustained attention. It is the first product from KHHM, a California lab working on the thesis that as information gets cheaper, the ability to think deeply about it becomes the scarce asset.

- Maker

- An AI that reads with you, not for you — 12 reading personas that argue with passages, ask Socratic questions, and adapt to the reader, and none of which will summarize the book.
- The library
- 70,000+ Project Gutenberg classics and 500+ hand-edited Standard Ebooks editions, plus the reader's own EPUBs and saved web articles.
- The interface
- Reading modes engineered for immersion — a paragraph reel and a sentence-at-a-time card mode — with print-grade typography and no engagement mechanics.
