Impressive! Really well done, Andrew.

One piece of feedback. I used the sample text and it gave me a sentence about a gold fish's memory and when I checked it, it had three errors. I had to update each error individually and over a longer sentence/thought/paragraph that might get cumbersome. It would be nice if there was a way to see a fully corrected sentence and point out the changes so I can do a one click change for a single sentence.
