AI-powered development tools are changing how engineers write, optimize, and maintain code. Among them, GitHub Copilot and Devin stand out as two leading AI-driven coding solutions.
Copilot enhances real-time coding with smart suggestions, while Devin takes a more autonomous approach, capable of managing full development workflows.
However, generating code is only the first step—ensuring AI-generated code is reliable, secure, and maintainable is just as important. If you're looking for a way to automate code quality checks, Greptile's AI code review platform helps teams catch potential issues, enforce best practices, and streamline the review process.
This comparison breaks down the key differences between these tools to help you decide which one best fits your workflow.
🔍 Feature Comparison
⚡ Code Generation
GitHub Copilot
Copilot offers real-time code completion, providing intelligent suggestions as you type. It understands context within the file and across your project, offering whole-line and full-function completions. Copilot is particularly effective at converting comments into working code, reducing the need for manual syntax lookups and speeding up development.
Devin
Devin operates at a higher level of autonomy, functioning as an AI developer rather than just a coding assistant. Instead of suggesting code, Devin can write, test, and debug entire programs. It handles multi-step development tasks, making it more useful for teams looking to automate software creation rather than just enhance individual productivity.
💬 AI Chat
GitHub Copilot
Copilot’s chat function is available within IDEs and through GitHub.com, offering natural language coding assistance, debugging help, and architecture suggestions. Developers can ask questions, request code explanations, and receive refactoring guidance, making it a valuable coding mentor within the workflow.
Devin
Devin’s chat is designed for project-level discussions rather than just coding assistance. It integrates with Slack and internal tools to facilitate team collaboration, respond to pull request comments, and provide insights on architectural decisions. Instead of answering questions, Devin executes tasks based on chat input, making it feel more like an AI teammate than a coding assistant.
🔍 Context Awareness
GitHub Copilot
Copilot understands the local file and project context, adapting to coding patterns and conventions. It provides useful completions based on previous code, ensuring suggestions remain relevant and stylistically consistent.
Devin
Devin goes further by maintaining long-term memory of projects, storing knowledge across sessions, and analyzing full repositories. It recalls previous decisions, adapts to coding style over time, and integrates with existing development processes, making it useful for large-scale, multi-developer projects.
🔒 Privacy & Security
GitHub Copilot
Copilot processes code suggestions locally and follows GitHub’s enterprise security policies. It does not store personal code and provides telemetry opt-out options. Enterprise users gain additional security features to manage access controls and compliance settings.
Devin
Devin provides enterprise-grade security, including SOC 2 Type II certification, data encryption, and VPC deployment options. It supports granular access controls, secure credential sharing, and custom data retention policies, making it a strong choice for organizations handling sensitive code.
