Quick actions are a feature of the In-editor AI assistant for Text notes which automatically triggers an LLM suggestion based on a defined prompt. The built-in quick actions come with a predefined prompt, but it is also possible to define your own quick actions.
In the Note Tree:
Afterwards, simply type in the content of the note the desired prompt. The text can be formatted in the same manner as a normal text note and it will be passed to the LLM as Markdown.
The title of the note will become the title of the quick action.
Of note:
Once a quick action is defined, the actoin will appear under the Quick Actions dropdown in a group called Custom.
