We add an intelligence layer to every document a publisher owns — books first, then everything that reads.
Contracts, curricula, journals, archives, novels. If it carries knowledge, it can carry intelligence. Built inside your systems, by a reading systems company with four decades of digital books.
Your systems. Our intelligence. Your name on the door.
No platform migration. No lock-in. We build knowledge-aware systems directly inside the publishing infrastructure you already run.
As the light changes, the book starts thinking.
Folio is an intelligence-first reading system — among the finest in the world. Annotation, conversation, narration, memory. Inside the book itself. Reading systems are the forty-year craft this company is built on; Folio is where the craft shows.
Nine instruments. One hand.
Each built by kaOS. Each operating today. Each installable on its own, inside your systems — and stronger together.
Pick what serves your list. We build it inside your systems.
Everything we build, open on a table.
The kaOS Library is free — a working playground for publishers, readers, students, professors, and knowledge professionals. Every service above, fully integrated, live. What you try here is what we build in your house.
