# E Teleprompter

> Free, professional, privacy-first online teleprompter studio with AI voice tracking flow, 70/30 beam-splitter glass mirroring, touchless gesture vision, and offline PWA capability.

E Teleprompter is a modern client-side web application engineered for video creators, keynote speakers, journalists, educators, and live broadcast studios. It operates 100% locally in the browser with zero server data retention, zero logins, and zero software installation.

## Core Capabilities

- **AI Voice Tracking Flow**: Automatic speech-synchronized scrolling that tracks speaking speed word-by-word with dual-channel Unicode & phonetic fuzzy matching (supporting English, Devanagari Hindi, and multilingual scripts).
- **2-Step Sequential Jump Verification**: Intelligent acoustic jump filter that confirms deliberate re-reading or jumping ahead only upon detecting 2 consecutive words, preventing accidental single-word homophone jumps.
- **4 Vocal Energy Modes**:
  - *Continuous Flow*: Smooth natural tracking with instant auto-pause on silence.
  - *Dynamic Speed*: Scrolling velocity scales dynamically with vocal projection (0.65x–2.2x).
  - *Vocal Push*: Advances forward in discrete line bursts per spoken sentence.
  - *Strict Gate*: Studio-grade 180ms cutoff binary gate for noisy studio environments.
- **Ultrasonic Acoustic Remote Controller**: Near-ultrasonic frequency modulation (16.6–18.6 kHz) allowing any smartphone to act as an instant wireless presentation remote controller over the air without Bluetooth, Wi-Fi, or software downloads.
- **MediaPipe AI Hand Gesture Vision**: 100% client-side camera landmark vision for touchless studio control (✌️ Pause, 🤟 Resume, 👆/👇 Scroll, 👍 Camera Off).
- **Reading Eye-Contact Guide & Focus Margins**: Customizable horizontal eye horizon line and adjustable column focus margins (100%, 75%, 60%, 50%) to maintain direct camera lens eye contact.
- **Formatting Cues & [PAUSE 3s] Markers**: Rich-text presenter cues (bold, italic, highlight, text scaling) and automated countdown timing markers (`[PAUSE 3s]`) that pause scrolling automatically.
- **100% Local Privacy & Offline Capability**: Progressive Web App (PWA) with IndexedDB local script storage and Service Worker caching. Audio and video streams never leave the user's device.
