Ascua™ is an AI-native book reader built around long-form DRM-free EPUB books. Read in calm typography, ask questions beside the page with clickable passage citations, and craft bespoke book layouts without altering a single word of the author’s text.
The light across the harbor settled into a single blue circle on the blank page—not an empty margin, Grandfather had written, but a promise to look closely before drawing a line.
The librarian did not ask which book Mara wanted. “Which question brought you here?” she asked. Mara explained the blank page. Together they compared the atlas with a sailor’s notebook. The notebook described a channel that appeared only at low tide.[1]
They kept the two accounts separate. A useful map, the librarian said, should show both what was known and what still needed checking.
When she returned to the reading room, the blue circle had become a drawing of the garden. The atlas had not supplied an answer. It had helped her notice where an answer might begin.
Most AI tools summarize books so you can skip reading them. Ascua is built for the opposite purpose: staying with demanding books longer, with quiet tools that respect the original text.
Start typing a question and Ascua automatically captures the passage in front of you. Every response links back to exact chapters and sections so you can verify interpretations against the author’s words in one tap.
Inconsistent publisher CSS often makes digital books tiring to read. Ascua generates tailored per-book typographic layouts and validates that every word, heading, and reading node remains 100% intact.
Import your own DRM-free EPUB books (with workspace conversion support for MOBI and AZW3 editions) or search and prepare public-domain literature from Project Gutenberg in seconds.
