AI Assistant Platform Wars: Google vs OpenAI vs Apple

Apple’s iOS 27-era Siri reportedly adds personal context, onscreen awareness, visual understanding, web answers, writing and dictation improvements, cross-device history, and systemwide actions. Google is broadening Gemini across Android, Windows, Workspace, travel, and home, while OpenAI is expanding ChatGPT toward computer use, coding, persistent context, app integrations, and possible dedicated hardware; Snapchat’s new assistant and Samsung’s One UI 9 show the same capabilities moving into consumer platforms.
