Features
Reading Companion
Not a chatbot. A reading partner with configurable personality — like TARS from Interstellar. Adjust proactivity, style, depth, and warmth. It can be a silent assistant, a Socratic mentor, or a friend reading alongside you.
Personality presets: Silent Helper, Reading Buddy, Academic Mentor. Fine-tune with sliders in advanced mode.
Ambient Intelligence
AI is woven into every surface. Turn to a new chapter — a context bar fades in with a recap. Select a word — a definition appears. AI surfaces cross-book connections in the margin. You never press an AI button.
4-layer reader AI: Context Bar (auto) → Inline Glossary (auto) → Margin Notes (auto, max 3/chapter) → Companion Panel (manual).
Insight, Not Statistics
No bar charts or heatmaps. AI narrates your reading journey: what domains you explored, which books connect to each other, how your interests are evolving. Notes organized by concept across all books, not scattered highlights.
Three layers: Reading Narrative (AI story) → Knowledge Network (concept graph) → Cross-Book Connections (thematic relationships).
TTS Audiobooks
Turn any ebook into a high-quality audiobook. Your companion reads to you in their configured voice. Server-side processing so your phone stays cool.
Backed by Kokoro / Edge TTS (server sidecar) + sherpa-onnx (on-device). Multiple voices, adjustable speed.
Smart Library
Import a book, it’s ready. AI auto-generates tags, summaries, difficulty level, and reading time estimates. Books group by topic, not filename. Search by meaning: “the book about procrastination” works.
Two-phase import: instant metadata parsing, then background AI enrichment. Batch import of 50 books handled gracefully.
Privacy as Freedom
A completely isolated hidden library with biometric access. Zero trace in the main interface. Full reading experience and AI inside. Privacy protects against others’ eyes, not your own reading experience.
Encrypted storage with platform keystore. Quick lock on app switch. Optional encrypted backup to separate WebDAV path.
Your personal librarian is waiting.
