Microsoft is continuing to shovel AI functionality into its Notepad application, with Windows Insiders the first test subjects. The latest update makes AI features like Summarize, Write, and Rewrite available on Copilot+ PCs without requiring a subscription. Since the update, users with Copilot+ PCs will be able to dispense with the subscription requirement and choose to run local models rather than cloud-based ones. Those with non-Copilot+ PCs that want a piece of the AI action, accessed via a right-click in Notepad, will need to subscribe.
