For help that understands your Windows screen, files, or settings, Microsoft Copilot is the most Windows-contextual choice in the available product documentation. For general-purpose drafting, brainstorming, summaries, coding questions, and image analysis, ChatGPT and Gemini are also credible options with dedicated Windows apps. There is no evidence-backed winner for every user: choose according to the tasks you need, account access, app compatibility, and whether you specifically need on-device processing.

Microsoft Copilot, ChatGPT, and Google Gemini each have documented Windows desktop experiences. Their feature lists describe what each product offers, not a head-to-head test of answer quality, reliability, or speed.

Which assistant should you choose?
Choose Copilot for help tied to Windows
Copilot is the natural first option to try when your question depends on what is on screen, a supported file, or a Windows setting. Microsoft documents Vision for browser windows and apps, screenshot sharing, file search, and directions to the relevant Settings page. For example, you can ask practical PC questions such as “What graphics card do I have?” or “What’s my current CPU usage?” Microsoft also documents questions about available space for a large game. These capabilities vary by account and rollout, so check what your app actually offers.

Choose ChatGPT for its desktop companion workflow
ChatGPT’s Windows app offers a quick companion window for asking questions and working with uploaded files or images.

The cited OpenAI page calls the Windows app an early version and cautions that it may not include every web or macOS feature, so confirm current plan eligibility and feature availability before relying on a particular capability.
Choose Gemini if its account access and requirements suit you
Gemini’s Windows app is suited to general tasks such as drafting, summarizing, brainstorming, coding help, and image analysis. Its documented requirements include a stable internet connection; the requirements do not establish that the assistant runs offline. For managed work or school accounts, access depends on administrator enablement.

Do you need a Copilot+ PC to use AI assistants?
No. A Copilot+ PC is not a general requirement for the consumer apps compared here. The NPU requirement applies to particular Windows AI APIs and certain on-device capabilities, not to installing and using Copilot, ChatGPT, or Gemini as consumer assistants.
Microsoft’s developer-oriented Windows AI APIs require a Copilot+ PC with an NPU. Its separate Foundry Local technology is documented for Windows devices with a DirectX 12-capable GPU; after a model is downloaded, inference runs on-device, and cached inference can continue offline. These local developer technologies are not prerequisites for the consumer assistant apps. Microsoft’s FAQ says of Windows AI APIs, “Input data is not sent to Microsoft servers”; that statement describes local API processing, not ordinary cloud-based assistant conversations. See Microsoft’s Windows AI FAQ.

What to consider before sharing your screen or files
Windows context can make an assistant more useful, but it also means you should pay attention to what you choose to share and which feature is active. Microsoft’s PC insights feature is opt-in and experimental, is gradually rolling out, and may provide incomplete or inaccurate responses. Microsoft says it requests permission before accessing relevant system or file data. The company also says personal files and system information are not stored or used for model training, while conversation activity may be used depending on settings. Review the current product and privacy settings for your account in Microsoft’s PC insights support page.
Microsoft described Copilot Vision availability as worldwide in markets where Copilot is offered in an October 2025 company blog. That dated vendor statement is not a guarantee that every Vision capability is available identically to every account today. Microsoft’s October 16, 2025 blog also reported twice as much Copilot engagement when people used voice compared with text; the cited passage does not describe its sample or methodology, and it is not evidence that voice improves productivity or that the result applies to other assistants. Microsoft Windows Experience Blog, October 16, 2025.
