Cursor Acquires Graphite, Completing the AI Programming Puzzle

Cursor announced its acquisition of Graphite, a fast‑growing modern code‑review platform, marking a significant signal for the AI‑driven programming era and indicating a restructuring of developers’ workflow.

Cursor is widely regarded as the best‑experienced AI code editor that transforms the "write code" inner loop, while Graphite reshapes the "merge code" outer loop with its advanced review capabilities.

"We never expected a tool like Cursor to change the industry so dramatically… our bottleneck shifted from writing code to reviewing and merging it," said Graphite CEO Merrill Lutsky in the official blog post.

The combined product envisions "self‑driving PRs": AI writes code in minutes, splits large features into clear incremental changes, automatically reviews and fixes CI errors, and queues merges without human oversight.

Tech blogger Gergely Orosz described the move as "Cursor is playing chess while others are still playing checkers," and predicted that GitHub will be chasing Graphite’s innovations such as Stacked Diffs by 2026.

What is Graphite?

Graphite’s core mission is to help developers merge code faster, primarily through its Stacked PRs feature.

Traditional GitHub flow

Develop feature A and open a PR.

Wait for peer review and CI to finish.

This is where it stalls. Continuing development on feature B becomes difficult because changes to A break B.

Result: developers waste time switching context or making temporary fixes.

Graphite’s Stacked PR flow

Develop feature A and submit.

Immediately start feature B on top of A, then feature C on top of B.

Graphite manages A → B → C as a stack.

Even if A is still under review, you can keep coding; any changes to A are automatically propagated to B and C with a single command.

Beyond Stacked PRs, Graphite offers a Merge Queue that resolves conflicts when multiple merges occur, keeping the main branch green, and an AI Reviewer that understands change logic and provides suggestions comparable to senior engineers.

Graphite’s team will join Cursor, but the product will remain independently operated, bringing together the best AI for code generation with the best AI for code management.
