TuitionStudio & Sinhala Prompter Pro
Creator Tools Suite
High-performance browser teleprompter and video lecture production workspace engineered for Sinhala educators and creators.
Overview
A specialized suite of digital creator tools developed to solve unique challenges faced by Sinhala video lecturers, YouTubers, and teleprompter operators.

Design decisions
The choices that shaped the system, and why.
- 1
Why Single-File Zero-Dependency HTML?
Content creators and studio operators often record in locations with zero internet connectivity. Making the teleprompter a standalone self-contained HTML file ensures it runs anywhere on any device (iPad, Mac, PC, Android) with zero server setup.
