In 2026, Apple plans to launch a completely rebuilt Siri that won’t just answer questions but will anticipate your needs, perform complex tasks across all your devices, and weave itself into the very fabric of iOS, macOS, and beyond. Unlike a standalone chatbot that you summon when you remember it exists, this Siri will live inside every app, every system setting, and every connected device—proactively offering help based on what you’re doing and what it knows about you. For the millions of Windows users watching from the sidelines, the move could redefine expectations for what an operating system’s AI assistant should do, and it puts Microsoft’s Copilot on notice.
This isn’t another chatbot bolted onto a voice interface. According to multiple reports from Bloomberg’s Mark Gurman and supply-chain leaks, Apple has spent years rebuilding Siri from the ground up around generative AI and on-device large language models. The result is a personal assistant that understands not just your words, but your context, your habits, and your entire digital life—securely and privately.
Siri’s 2026 Overhaul: What’s Actually Changing
The new Siri is a radical departure from the current version, which often struggles with multi-step requests and feels disconnected from the rest of the system. Here’s what the 2026 version will bring:
- On-device LLM processing: Most requests won’t need the cloud. Siri’s language model runs directly on your Apple Silicon chips, preserving privacy and enabling instant responses even offline.
- Cross-device continuity: Start a task on your iPhone, and Siri picks it up on your Mac, iPad, Apple Watch, or Vision Pro. Its “memory” of your activity moves with you, thanks to a unified personal context layer.
- App Intents v2: Apple is expanding its developer API to let third-party apps expose deep actions Siri can string together. Imagine telling Siri, “Find the photos from last weekend, turn the best three into a collage, and text it to the family group,” and it just does it—opening apps only when necessary for previews.
- Screen awareness: Siri can see what’s on your screen and act on it. If a friend texts you a restaurant recommendation, you can say, “Add that place to my favorites in Maps and book a table for Friday,” and Siri will pull the address from Messages, create a Maps favorite, and open the reservation app.
- Proactive intelligence: The assistant will surface suggestions before you ask, like reminding you to leave for a calendar appointment based on live traffic, or offering to start your coffee maker when your alarm goes off.
Reports indicate Apple is calling this a "personal intelligence system" rather than a voice assistant. It’s designed to be invisible yet omnipresent, handling routine digital chores so you don’t have to think about them.
What This Means for You
The impact of Apple’s new Siri will vary dramatically depending on which ecosystem you’re in.
If You’re Deep in the Apple Ecosystem
For iPhone, Mac, and iPad users, the 2026 Siri could be transformative. No more tapping through a dozen steps to share a file or set up a complex automation. The assistant will understand your relationships, your preferences, and your daily patterns. For instance, if you always send a weekly email summary to your team, Siri might pre-draft it based on your recent documents and messages. Privacy remains a core promise: on-device processing means Apple doesn’t see your data, and the company is expected to introduce an opt-in “Personal AI Profile” that further personalizes the experience without phoning home.
If You’re a Windows User or IT Pro
Microsoft’s Copilot has made strides, but it remains primarily a conversational overlay and a glorified search bar. The deep system functionality that Apple is promising—screen awareness, cross-app task chaining, offline processing—simply doesn’t exist in Windows today. That could make Windows feel archaic if you’ve also got an iPhone and start expecting your PC to behave as intelligently as your phone.
For IT administrators, the shift carries strategic weight. Employees who use iPhones and Macs may become significantly more productive with a proactive, integrated assistant, potentially accelerating enterprise adoption of Apple hardware. This puts pressure on Microsoft to deliver something similarly seamless in Windows, perhaps through a future Copilot that can actually control settings, files, and apps at a granular level.
For Developers
Apple’s App Intents framework will likely become a critical integration point. Developers who embrace it can make their apps feel native to Siri’s brain, while those who ignore it may find their apps left out of the automation loop. For Windows developers, this is a reminder that deep OS integration—like what Windows once offered with Cortana and its speech APIs—can give an assistant real power, if the platform holder invests heavily.
How We Got Here: Siri’s Long Road to Relevance
Siri was groundbreaking when it launched in 2011, but Apple failed to keep pace. As Alexa and Google Assistant gained conversational abilities and smart-home skills, Siri stagnated. The real earthquake came in late 2022 when ChatGPT demonstrated what a large language model could do, making all voice assistants look instantly obsolete.
Apple was flat-footed. Internal projects like “BlackRock” (a Siri replacement) were accelerated, and the company went on an AI startup acquisition spree. By mid-2024, iOS 18 introduced the first signs of the new Siri: on-screen awareness, personal context understanding (still limited), and the ability to handle more natural language. But it was clearly a stopgap. The real engine, code-named “Ajax,” is said to be the foundation for the 2026 overhaul—a comprehensive, privacy-first AI stack that replaces Siri’s aging architecture.
Microsoft, meanwhile, bet heavily on OpenAI. Copilot in Windows 11 is built on GPT technology, but it’s still mostly a sidebar chatbot that can tweak a few settings. The deep integration that Apple is promising—reading your screen, orchestrating apps, handling your files—has no equivalent on Windows yet. Microsoft has teased a “Windows Copilot Runtime” for later versions, but we haven’t seen the kind of system-wide fabric Apple is reportedly building.
What to Do Now: Actions for Windows Enthusiasts and IT Pros
If you’re a Windows user, you don’t need to switch platforms. But you should be paying attention to what’s coming—and pushing Microsoft to respond.
- Experiment with current Copilot and voice features. The Windows 11 2025 Update (version 25H2) is expected to bring some limited system controls, such as adjusting settings and managing apps. Test these capabilities to understand the baseline.
- Monitor WWDC 2026. Apple will almost certainly unveil the new Siri there. Watch how it handles real-world tasks, and compare its fluidity to what Copilot can manage.
- Give feedback to Microsoft. The Windows Insider program and Feedback Hub are direct lines to the Copilot team. If you see features you want—like cross-app automation, screen reading, or offline processing—request them. The more voices, the better.
- For IT decision-makers: Consider piloting a few Macs or iPad Pros when the new Siri lands, especially for roles that involve heavy multitasking or mobility. Measure whether the productivity gains are real, and feed that data into your hardware planning.
Outlook: The AI Assistant Wars Heat Up
Apple’s move will force a reckoning for every major platform. Google will likely accelerate similar deep integration in Android and ChromeOS. Amazon’s Alexa is already being reimagined with generative AI. But for Microsoft, the challenge is existential: if Windows can’t keep up with the “intelligent OS” vision, it risks losing users who demand more than a chatbot.
We expect Microsoft to respond by evolving Copilot into a true system agent, perhaps leveraging its partnership with OpenAI’s upcoming models that can operate software. The race is on, and the assistant that best combines privacy, utility, and ecosystem depth will win the day. In 2026, for the first time in over a decade, Siri might just be that assistant.
