| Description | Context is an innovative app available for iOS and macOS that makes understanding sentences easier by letting you copy and select words to get explanations via ChatGPT.

It's a useful tool for anyone who frequently encounters unfamiliar words or phrases and needs quick, reliable explanations. Although it comes with a 100-time free trial, continued use requires a subscription, as it relies on cloud computing and ChatGPT services. | OppenheimerGPT is a macOS application designed for using AI models like ChatGPT and Gemini side-by-side, enabling users to input prompts once and receive responses from both models simultaneously. The app offers a Pro version for $4.99 which includes features such as menubar access, unlimited standalone windows, and over-the-air updates, while the Basic version remains free but with limited capabilities. |
