The first step is to place the cursor from where you want the AI to start generating content. In the adjacent image, the cursor is placed at the end of the second paragraph.
Once you place the cursor, click on the Write More feature to generate content, as shown in the image.
AI generates content based on the context (around 100 words before the cursor). This feature is a supercharger, and you can keep using the feature on and on and on.
If you're using the Write More feature, adding some content in between to help avoid the AI from losing the context is helpful.
If you wish to operate hands-free, use the keyboard shortcut, 'Control + Q', to use the Write More feature.
