# Writing Tools

Add support for Writing Tools to your app’s text views.

## Discussion

Writing Tools provides a simple way for people to improve what
they write using your app. Text views that support Writing Tools
gain the ability to proofread, rewrite, summarize, or compose
content with the help of system-provided large language models
(LLMs) and Apple Intelligence.

Writing Tools supports both the standard system views and custom text
views you create. The [`NSTextView`](/documentation/AppKit/NSTextView) and [`NSTextField`](/documentation/AppKit/NSTextField) classes
automatically support Writing Tools, but you can customize that support
to suit your app’s requirements. You can also add Writing Tools support
to any [`NSView`](/documentation/AppKit/NSView) in your app that contains text.
