In fairness
where sudowrite is better.
Sudowrite’s own fiction model produces more prose, faster, and it has years of features for generating and expanding text. If you want the machine to draft whole scenes for you, it is the stronger tool. Buildblur’s built-in AI runs on free models and is deliberately smaller.
