Artificial intelligence (AI) has rapidly transformed the software development landscape, revolutionizing how engineers write, review, and optimize code. AI-powered coding assistants have become an integral part of modern software engineering, with GitHub’s latest survey revealing that the vast majority of developers now rely on AI-assisted coding tools.
Y Combinator partner Jared Friedman highlighted this shift by stating:
"A quarter of YC’s W25 startup batch have 95% of their codebases generated by AI."
This represents a seismic shift in coding practices, where AI is no longer just an assistant but a primary contributor to software development. The emergence of sophisticated AI-powered code review platforms is further accelerating this trend, ensuring that AI-generated code is robust, secure, and optimized.
Among the notable players in this space is Graphite, an AI-powered code review platform that has quickly gained traction among startups and enterprises alike.
Graphite’s Evolution: From Internal Tool to Industry Leader
Origins and Growth
Graphite was founded in 2020 by former engineers from Meta, Airbnb, and Google under the corporate name Screenplay Studios Inc.. The platform initially functioned as an internal tool to streamline code review processes but soon evolved into a full-fledged commercial solution.
Merrill Lutsky, co-founder of Graphite, explained the motivation behind its development:
"Graphite started as an internal tool we built to solve our own pain around code review. We shared what we built with a few ex-Meta engineers, who quickly shared it more broadly, and soon the demand for Graphite became too loud to ignore."
This organic growth was fueled by word-of-mouth adoption within elite engineering circles, particularly among ex-Meta and ex-Google engineers accustomed to sophisticated internal code review systems.

The Future of AI in Code Review
Will AI Replace Human Code Reviewers?
Despite advancements in AI-powered tools, human reviewers remain indispensable in software development.
Aspect | AI Capability | Human Expertise Needed? |
Bug Detection | Can catch syntax and logic errors. | Yes, for context-sensitive issues. |
Security Audits | Detects common vulnerabilities. | Yes, for in-depth threat analysis. |
Code Optimization | Suggests refactoring. | Yes, for architecture decisions. |
Compliance & Ethics | Can flag license violations. | Yes, for legal and ethical reviews. |
As AI matures, its role will shift from a simple assistant to a collaborative partner, allowing developers to focus on higher-level problem-solving while AI handles repetitive tasks.
