The AI-Powered Digital Publishing Platform.
Stop paying for a reader, a separate annotation app, and a third tool for flashcards that don't talk to each other. Aeion Manuscript turns any EPUB into an interactive study companion — an AI tutor that explains, translates, and simplifies text in context, word-timed text-to-speech built for accessibility, and flashcards and study guides generated automatically from what's actually on the page — all natively wired into Aeion OS.
Intelligent Publishing Operations
Text-to-Speech with Word Timestamps
Every word gets its own start/end timestamp, so the narration highlights exactly what's being read as it's read — screen-reader and low-vision users can follow along in real time instead of guessing where the audio is in the page. Runs across OpenAI, ElevenLabs, Azure, or Polly, and a 30-day cache means the same passage never gets regenerated (and re-billed) twice.
AI Text Analysis
Highlight any passage and ask for an explanation, a translation, a simplified version, or a definition — with full book context, so the answer is about _this_ character in _this_ chapter, not a generic dictionary lookup. Conversation history means follow-up questions build on what was already asked.
Flashcard Generation
Turns a chapter into a study deck automatically — front/back cards pulled straight from the text, scheduled with spaced repetition so review happens right before a student would otherwise forget, and quiz mode built in so studying doesn't require a separate app.
Study Guide Creation
Generates key concepts, discussion questions, and important quotes at whatever depth you need — a quick chapter summary or a full unit study guide — and exports straight to PDF for class handouts.
EPUB Import & Processing
Drop in an existing EPUB and Aeion parses chapters, metadata, and table of contents automatically — your existing library becomes interactive without anyone re-typing a single page.
Annotation System
Highlights, bookmarks, notes, and vocabulary lists in one place, color-coded so a student can tell "important quote" from "word I don't know" at a glance — and vocabulary words feed straight into spaced-repetition review.
Book Management
One library view for every title, with reading progress, reading goals, and genre categorization tracked automatically — so a teacher or parent can see who's actually reading, not just who checked a box.
Reading Experience
Font, theme, and layout adjust to how each reader actually reads, with progress synced across devices and reading statistics that show time-on-page, not just "started" or "finished."
Background Processing
EPUB processing, TTS generation, and AI analysis all run in the background, so uploading a 400-page book or requesting a full-book study guide never freezes the reading experience while it works.
Why Readers Switch
Accessibility that actually works
Word-level TTS timestamps let screen-reader and low-vision users follow along in real time, not just hear a passage read aloud.
Higher test scores
Flashcards auto-generated from key passages become part of the study routine, reinforcing material before exams.

Frequently Asked Questions
Authors, publishers, and editorial teams managing book / long-form / serialized content. Handles draft management, version control, editorial workflow (writer → editor → copy-editor → typesetting), royalty tracking, and rights / licensing for adaptations.
Scrivener is a single-user authoring tool. Google Docs is collaborative writing without publishing workflow. Aeion Manuscript is built for the whole pipeline — collaborative writing + structured editorial review + commercial publishing. Royalty calculation against sales reports from Commerce; rights tracking for film / translation deals.
Yes — same source produces EPUB, KPF (Kindle), PDF print-ready, web reader. Style overrides per format; conditional content ("this chapter only appears in the hardcover edition") supported.
State machine — draft → first-pass-edit → revision → copy-edit → final → typeset → proofread → ready-to-publish. Each transition has acceptance criteria; comments + suggestions tracked per paragraph; version history with diff-view across revisions.
Yes — splits defined per work (50/50 between co-authors, 5% to ghostwriter, etc.) with optional ramp-up ("after 10K units, ghostwriter goes to 8%"). Payouts settle via your configured rail at sales-period close — Stripe Connect for split payments, or a manual export from the royalty ledger.
