Chat interface for writing

I use Guided Write a lot. AutoComplete is too likely to go in a different direction than I had in mind. However, the current card-based workflow is inconvenient and breaks the creative flow, because the text appears in a separate place so you cannot immediately see how it fits into the preceding text.

What I would like to have is a separate chat input field below the prose window, where I can enter what happens (i.e. the input to Guided Write). Then the text would appear at the cursor location in the prose window in a slightly different color, just like text inserted from a card currently does, and not yet editable. In the chat input field there would also be forward and backward icons and the version currently being viewed (“< 1/2 >”), which allows you to create a new version for the current generated text and to switch between generated versions, and a length selector similar to current Guided Write. Finally the chat input field would have an Accept button that accepts the generated text, which adds it to the prose (changing color to the normal color of prose, and making it editable).

Below is a quick mock-up to illustrate the concept:
