Meet Graphite Agent: The next evolution of AI code review

Graphite announces Graphite Agent, unifying their AI reviewer (Diamond) and Chat features into a single AI code review experience. Unlike traditional AI reviewers that only provide comments, Graphite Agent acts as a collaborative tool that reviews, edits, and helps merge PRs directly within the pull request interface. The company is integrating AI capabilities into all pricing tiers, with new plans starting at free for individuals, $20 for Starter, and $40 for Team (including unlimited AI reviews). All plans include a 30-day free trial without requiring a credit card, and existing customers will transition to new plans after January 8, 2026.
