Context is an iOS/macOS tool designed to aid serious foreign language readers. It enables users to understand sentence meanings by utilizing an AI. Unlike direct AI interaction, Context streamlines the process. Users copy a sentence, and select words, and ChatGPT provides explanations. The tool not only explains sentences but also offers saving, syncing across devices, and data export. A widget enhances convenience. While not free, Context has a 100-word lookup trial before payment. Subscription options are $0.99 or $2.49 monthly due to ChatGPT and cloud service costs. Developed by Chen Guo, Context encourages immersive reading, easy review, and a slower pace, serving language learners and foreign language enthusiasts effectively.
