1. reordering the hunks in a "more relevant" order (instead of alphabetical)
2. adding some "fluff text" to connect the hunks together in a narrative
In practice, the reordering doesn't shorten the review time that much (and extends it greatly when the order is illogical), and the AI "explanations" rarely add value. The second video's Review Guide in TFA is way longer than the diff itself.
I much prefer the strict 2-pane setup with rationale and diff strictly separated, and the "self-review" author comments in the diff provide the context for reviewers.
Other similar attempts at this UI this year:
- by Graphite https://graphite.com/blog/code-tours (April)
- and CodeRabbit https://www.coderabbit.ai/blog/introducing-change-stack-the-... (May)
Is this seriously supposed to replace Pull Requests?
