The accessory attaches to a smartphone and provides a low-power, high-contrast display for reading text, notifications, and live transcriptions. Integrated microphones capture voice recordings while [AI software processes audio into text](https://www.trendhunter.com/trends/the-amber-case), allowing users to review both written and spoken notes on the external screen without opening the phone’s native apps. The E-Ink display is sized to cover the back of the phone while remaining viewable in various lighting conditions. Recording controls and playback functions are accessed through a button interface on the case’s edge. Transcriptions generated by the built-in AI can be scrolled and edited directly on the external display or synced with connected devices. Power is supplied through the phone connection or a dedicated battery within the case, with the E-Ink screen designed for minimal energy use during reading and transcription tasks.
