Signboard

Signboard is a simple and efficient Chrome extension designed to display your messages in extremely large letters, utilizing the entire screen area. Whether you need to show billing info to a seller, a pick-up sign at the airport, or request help in an unfamiliar language, Signboard makes your message impossible to miss.

Featuring intuitive controls like single tap to swap colors, double tap for quick exit, and long touch to edit content, it offers ease of use. The extension also supports widget functionality with each widget displaying its own message, and it integrates smoothly with other apps such as Google Translate to quickly share and display translated text. Moreover, Signboard is lightweight, ad-free, requires no permissions, and even supports developer integration through Intent for custom use cases.
