We’ve always believed that pull requests should be where you build, not where you wait. In the Graphite Chat open beta, developers collaborated with AI right in their pull requests—reviewing, editing, and merging without leaving the PR page. Today, we’re taking the next step. We’re unifying Diamond (our AI reviewer) and Chat into one experience and giving it a new name: Graphite Agent.
This shift represents the next evolution of AI code review. Other AI reviewers stop at comments, but developers need more than just async feedback from a bot; they need a true collaborator that helps them create, edit, and merge AI-generated PRs safely and efficiently. Graphite Agent not only explains and critiques your code, but it also helps you act on that feedback by fixing issues, updating PRs, and merging your code collaboratively. It’s review, conversation, and iteration, all in one flow.
We believe AI is not just an add-on—it’s table stakes for modern tools. That’s why we’re integrating Agent into every Graphite plan, giving all developers, regardless of team size or budget, access to best-in-class AI code review tooling. AI should empower all developers, not just a select few, and today’s change aligns our plans with that core belief.
What’s changing
With this unification, you can expect a few changes to your Graphite experience:
Renaming Diamond + Chat to Graphite Agent
We’re retiring the “Diamond” name and bringing together our AI offerings under the umbrella of Graphite Agent. The name ties together how we think about AI interacting with your code, your questions, and your merges. Specifically, Graphite Agent combines:
AI PR reviews: Get instant feedback, suggestions, and fixes applied directly in your diff.
Chat: Follow up on suggestions, ask clarifying questions, and apply changes conversationally.
This is more than a rename; Graphite Agent is an end-to-end experience that helps you go from feedback to commit in one conversation.
Create, review, and merge, all in one place
Graphite now brings the entire code review workflow into one platform, eliminating the need to context switch between multiple tools:
Create → Stacked PRs: Break big PRs into smaller, more manageable diffs for easier review by you, your teammates, and your AI agents.
Review → Modern PR page, AI reviews, & Chat: Fast, intuitive, and integrated with your full tool stack (GitHub repos, CI pipelines, and more) so nothing slips through the cracks.
Merge → Stack-aware queue: Keeps merges conflict-free and ensures your code moves forward smoothly.
New pricing and packaging
We’re simplifying our plans by consolidating Graphite’s core features and Diamond into different packages. Here’s what that looks like at a high level:
Hobby plan (free): For individuals reviewing agent-generated code in personal repos.
Starter plan ($20): Stacking and limited Agent interactions (reviews + chat) for individuals and small teams.
Team plan ($40, most popular): Unlimited AI reviews and chat with Graphite Agent, stacking, merge queue, and advanced team features. That’s $5 cheaper than Core + Diamond combined today, and the same price as Cursor BugBot.
All plans include a 30-day free trial, which will not require you to put down a credit card. See the full pricing grid here.
Existing customers will remain on their current plans until their first renewal after January 8, 2026, when they’ll automatically move to the new Team plan. You’re free to make changes to your plan at any time before that, though.
Building the future of AI software development
Today, every developer has access to incredibly powerful AI tools that generate code faster than ever. The world’s top engineering orgs are quickly realizing that code review is the new bottleneck, and that to truly unlock the potential of AI software development, they need tools that help them review code just as quickly as they can generate it.
Today’s announcement of Graphite Agent and our new pricing is the next step in our mission to make code review more powerful, more human, and more frictionless. Whether you’re a solo dev or part of a large team, it’s time to experience an AI code reviewer that doesn’t just comment—it collaborates with you. You can start using Graphite Agent completely free for your first 30 days. Get started here.
