INTRODUCING VOCALYZE 4.0 — DESIGNED FOR FOLDABLE IPHONE DUO
Vocalize AI is now built from the ground up for Apple's foldable form factor, transforming physical hardware postures into productivity superpowers while continuing to run 100% on-device.
TABLETOP POSTURE: HANDS-FREE RECORDING & LIVE NOTES
- Rest your phone on any table or desk in tabletop posture (90°–115°).
- Upright Top Screen: displays high-definition real-time audio waveforms, elapsed time, live speech-to-text transcription, and privacy indicators ("No Audio Stored" in Live Notes).
- Base Bottom Screen: generous tactile controls for Pause, Stop, timestamped Bookmarks, action notes, and text entry.
- Intelligent Audio Tuning: automatically beamforms microphone capture to the top facing array and suppresses mechanical haptics during recording.
BOOK POSTURE: AI STUDY COMPANION
- Angle the device like a book (110°–150°) to unlock a dual-pane study workspace.
- Left Pane: distraction-free document reader with synchronized word-by-word read-aloud.
- Right Pane: docks your AI Study Companion sidecar—instantly view AI Summaries, generate interactive Quizzes and Flashcards, converse with "Ask Document", or configure Audio Overviews without interrupting your reading flow with modal sheets.
DUAL-DECK AUDIO SUITE
- In Tabletop posture, the Audio Editor cleanly separates into an upper visualizer deck (master waveform & spectral FFT) and a lower control deck (precision jog-wheel scrubber, trim & split markers, and AI Voice Separation sliders).
SEAMLESS HARDWARE CONTINUITY
- Move between Cover Screen, Book Posture, Tabletop, and Unfolded Flat without audio playback stuttering or recordings dropping frames.
- Crease Safe-Area: typography, buttons, and reading text automatically adapt to avoid straddling the physical hinge.
All transcription, document processing, and AI features remain strictly private and on-device.

SEARCHABLE DOCUMENTS, SMALLER FILES
- Scan Paper, Take Photo, Photos, and Files imports now share the same searchable-PDF optimization pipeline.
- Searchable PDFs use bounded 200-DPI JPEG page images, reducing storage while preserving fine print, highlighting, handwriting, receipt detail, OCR text, and read-aloud behavior.
- Existing native searchable PDFs remain unchanged by default.
RELIABILITY AND LIBRARY IMPROVEMENTS
- More reliable Spotlight indexing, title updates, and library backfill.
- Improved audio playback speed display, calendar/reminder actions, microphone restoration, and inline Audio Overview navigation.
