Toolglade’s take

Graphite is distinctive because it pairs a genuinely useful stacked-PR workflow with codebase-aware AI review, so it appeals to teams that want both process and feedback improvements. The AI reviewer's whole-repo context is a real advantage over diff-only tools, and setup is refreshingly light. Naming churn (Diamond folding into Graphite Agent) can make docs confusing, and the stacked-diff paradigm has its own learning curve. Best for fast-moving teams on GitHub who are open to changing how they structure PRs.

About Graphite

Graphite combines a stacked pull request workflow with codebase-aware AI code review via Graphite Agent, giving instant, high-signal PR feedback that keeps humans in the loop.

Graphite began as a stacked-diff workflow tool that makes it easier to break large changes into small, reviewable pull requests and manage them as a stack. On top of that workflow, Graphite added AI code review, originally launched as Diamond and now delivered through Graphite Agent, which reviews PRs with an understanding of the entire codebase rather than just the diff. The AI reviewer delivers high-signal comments on bugs, logic errors, style, and security, with the company reporting a low negative-comment rate across hundreds of thousands of reviewed pull requests. It requires little more than connecting a GitHub repository, and the free plan automatically reviews a capped number of PRs per month, so teams can trial it without adopting Graphite's other tools. Graphite raised a $52M Series B tied to its AI review launch and positions itself alongside CodeRabbit and Greptile in the AI code review space, while emphasizing that AI augments rather than replaces human reviewers.

TL;DR

Graphite blends a stacked-PR developer workflow with codebase-aware AI code review, ideal for fast-shipping GitHub teams.
