OpenAI has recently announced the availability of the ChatGPT app for Mac to all users, following a previous limited rollout to ChatGPT Plus subscribers. Designed to simplify user access to ChatGPT for questions related to email, screenshots, websites, and other content on Mac, the app includes features such as Voice Mode for voice conversations, search capabilities for past conversations, and more. With the latest version, GPT-4o, accessible for free but with a limited number of requests, users can now leverage the app without the need for a subscription plan. Additionally, OpenAI has partnered with Apple, integrating ChatGPT into iOS 18, iPadOS 18, and macOS Sequoia - allowing Siri to utilize ChatGPT for complex queries with user consent. This collaboration aims to enhance user experience and accessibility across Apple's platforms.
