The most important thing about Cursor's new PR Review is not the review...
It's what it connects
Cursor just closed the full development cycle inside the IDE
And to understand it, you need to see the three pieces together:
1/ Build in Parallel: Cursor breaks a plan into independent subtasks and runs them with async subagents, maintaining order when dependencies exist.
2/ Split PRs: Cursor takes a large diff and proposes splitting it into smaller, mergeable PRs - identifying logical slices before creating them.
3/ PR Review: Inline threads, general comments, file tree, reviewer status and quick actions to move forward without leaving the editor.
The old flow looked like this:
Idea, code, massive diff, GitHub, review, comments, back to editor, fixes, GitHub, merge.
Cursor is turning it into:
Plan, parallel execution, logical split, PR, review, fixes, merge.
All inside the same environment.
But the most interesting read isn't the convenience.
It's that Cursor is solving the problem they created.
When agents produce more code, a new problem appears: more diffs, more PRs, more reviews, more risk of mixing responsibilities.
The underlying message is clear:
Cursor doesn't want to be just an AI editor.
It wants to be the operational layer over the full software lifecycle.
Plan, build, split, review and merge without jumping between editor, GitHub and terminal.
That positions them differently from GitHub Copilot, Claude Code or Devin.
A new PR review experience is now available in Cursor 3.
Take PRs from creation to merge, all in one place.
You can see comments, diffs, commits, and review status to understand what changed and next steps. Navigate larger PRs more quickly with the file tree and changes picker.
