The Challenge: Heavy and Inefficient Teleprompters
Most teleprompters on the market suffer from outdated interfaces, expensive subscription models, or poor performance that distracts content creators. The goal was to create a tool that was:
- Lightweight: No unnecessary dependencies.
- Fluid: Consistent 60fps scrolling.
- Functional: With real features needed for pro creators.
Innovation: Notch Mode
One of the main features is Notch Mode. Inspired by modern hardware design, it allows positioning a small, minimalist window just below the webcam, naturally maintaining eye contact with the audience without the need for expensive hardware.
Technical Decisions
- Electron: To ensure native Windows compatibility and fast deployment.
- Vanilla JS: I decided not to use frameworks (React/Vue) to ensure maximum rendering speed for text scrolling, which is critical for a teleprompter.
- Content Protection: Implementation of native APIs to prevent accidental screen captures of confidential scripts.
Key Features
- Notch Mode: For perfect eye contact.
- Smart Scroll: Full control of speed and position.
- Global Shortcuts: Control the prompter without losing focus on your recording app.
- Dynamic Themes: Optimized for high or low light recording environments.
Impact
ProPrompter was born out of a personal need and became a tool used by creators seeking simplicity and power. A testament that “Bare Metal” in JS still has a prime place in high-performance applications.
