OpenAI's latest acquisition adds the team behind Sky, a Mac app that understands your screen, as it races Apple to make AI that actually helps you work.

The deal was announced October 23, 2025, and brings Sky's entire team, led by co-founder and CEO Ari Weinstein, into OpenAI. Sky will be folded into ChatGPT, bringing its deep macOS integration and user-focused design to the popular AI assistant.

Sky is a lightweight AI layer for the Mac that "floats" over the desktop and works within your apps. It can understand what's on your screen and perform actions such as writing, planning, or coding assistance without switching contexts.

A natural language interface assists users in completing tasks in Sky. It integrates smoothly with macOS instead of acting like a separate chatbot.

OpenAI Vice President Nick Turley said the acquisition moves ChatGPT toward becoming an active helper rather than a passive responder. Turley credited Sky's deep Mac integration with accelerating OpenAI's goal of bringing AI directly into the tools people already use every day.

Weinstein, who co-founded Workflow and sold it to Apple in 2017, said Sky was built to make computers more intuitive and personal. He called OpenAI the right partner to expand that idea to a wider audience.

How Sky works

Sky runs as an overlay using macOS accessibility APIs to identify what's on screen. It can summarize text, automate actions, and control apps through natural language.

Early testers compared it to Apple's Shortcuts app fused with ChatGPT's understanding. Instead of asking ChatGPT to "write an email," a user could tell it to send one directly through Apple Mail or Gmail.

Sky's ability to recognize open windows and app states might finally provide ChatGPT with genuine desktop control. OpenAI's plug-ins and custom GPTs have only managed to achieve this partially.

The company hasn't announced when Sky's technology will be in ChatGPT. OpenAI usually introduces new features in its Plus and Team plans before a wider release.

Why it matters

The acquisition fits into OpenAI's growing focus on user-facing products. ChatGPT is available on the web and mobile, but it still feels like a chatbot rather than a built-in assistant.

By adding Sky's contextual awareness, OpenAI aims to make ChatGPT behave more like part of the operating system, seeing what users are doing and acting accordingly.

That ambition mirrors Apple's direction with Apple Intelligence, coming to future updates in macOS Tahoe and iOS 26. Apple's system will let Siri understand on-screen content and perform contextual tasks like replying to emails or editing photos.

The bigger picture

For Mac users, ChatGPT might soon change from a standalone app to a background assistant. The assistant could understand and react to what's happening on the screen.

Power users might appreciate the closer integration into their workflow. However, Apple might view it as competition for Siri's growing role in Apple Intelligence.

Neither company has shared any financial details. OpenAI mentioned that Sky's integration is already in progress. If Sky's context engine works as promised, ChatGPT could become a real desktop companion.
