Ultra-lightweight, hardware-accelerated teleprompter built with Rust & Tauri.
Note : The next major update (v2) will take a little longer than usual as I modularize the codebase and finalize the Pro/Free tier split. Once v2 drops, I'll be right back to the regular 1-2 weekly update schedule!

Caution
If you are encountering scaling issues please download the latest version (1.9.0). If flow doesn't start scrolling on voice tracking mode, please check the microphone permission settings for the app and make sure the correct input device is selected in settings.
Important
Distribution note: the Microsoft Store edition is planned to become a Pro version. Its price is expected to increase to 5-10 USD (Not decided yet) to help compensate for server rental, and hosted services will be turned on once the Pro release reaches the required user threshold. The GitHub version will remain the free open-source build and will continue receiving major features and updates.
