Software start-up Graphite has introduced “Graphite Chat,” an artificial-intelligence agent that sits inside pull-request workflows and conducts real-time code reviews. Rolled out on 19 August, the tool lets developers highlight code, ask natural-language questions and receive explanations, security assessments and recommended fixes within the same interface. Graphite says the agent can identify bugs, resolve errors and automatically apply approved changes, turning the review stage into an interactive development step rather than a bottleneck. Early users who were given preview access report that the system can update pull requests with a single click and provide context-aware breakdowns comparable with dedicated AI coding assistants. The launch underscores the accelerating push to embed generative AI deeper into software-engineering pipelines, as vendors from start-ups to established platforms race to shorten development cycles and improve code quality with automated assistants.
