Master GitHub Copilot Review (2026) with our step-by-step tutorial, detailed feature walkthrough, and expert tips.
Sign up for a GitHub account at github.com (or sign in if you already have one), then visit github.com/features/copilot and select the Free plan to start immediately Install the GitHub Copilot extension in your IDE — search "GitHub Copilot" in the VS Code Extensions marketplace, JetBrains Marketplace, or your preferred editor's plugin store Open any code file and start typing — Copilot will show inline ghost
text suggestions automatically; press Tab to accept or keep typing to ignore Open the Copilot Chat panel (Ctrl+Shift+I in VS Code) to ask questions about your code, request refactors, generate tests, or debug errors conversationally Upgrade to Pro (/month) when you hit the Free tier's 2,000 completion or 50 chat request monthly limits
💡 Quick Start: Follow these 2 steps in order to get up and running with GitHub Copilot Review (2026) quickly.
Explore the key features that make GitHub Copilot Review (2026) powerful for coding agents workflows.
Ghost-text completions appear as you type, suggesting single lines, entire functions, or boilerplate blocks. Trained on billions of lines from public GitHub repositories, suggestions are contextually aware of your current file, imports, and variable names. Accepts via Tab with zero friction.
A conversational AI assistant embedded directly in your IDE sidebar or inline. Understands your workspace context — open files, project structure, terminal output — and can explain code, suggest refactors, generate documentation, write tests, and debug errors without leaving your editor.
An autonomous coding mode where Copilot iterates on multi-step tasks: planning changes across files, running terminal commands, fixing lint errors, and self-correcting until the task is complete. Available in VS Code with GPT-5 mini and other models. Transforms Copilot from a suggestion engine into an active coding partner.
Assigns GitHub issues directly to Copilot, which creates a branch, writes code, runs tests, and opens a pull request autonomously — all in a cloud sandbox. Available on Pro+ and Enterprise. Handles low-to-medium complexity tasks like bug fixes, test additions, and feature scaffolding without developer intervention.
Works natively in VS Code, Visual Studio, JetBrains IDEs (IntelliJ, PyCharm, WebStorm, etc.), Eclipse, Xcode, Neovim, and GitHub Mobile. Unlike competitors that require proprietary editors, Copilot meets developers in whatever environment they already use.
Connects to Model Context Protocol (MCP) servers across all paid plans, enabling Copilot to interact with external tools, databases, APIs, and documentation sources. Extends Copilot's knowledge beyond your local codebase into your entire development ecosystem.
Automated pull request reviews powered by AI that catch bugs, suggest improvements, and flag security vulnerabilities. Copilot Autofix identifies and patches common security issues like SQL injection, XSS, and hardcoded secrets directly in the PR workflow.
Pro+ users can switch between frontier models from OpenAI (GPT-5, o3-pro), Anthropic (Claude Opus 4, Claude Sonnet 4), Google (Gemini 2.5 Pro), and others. Choose the best model for each task — creative coding, precise refactoring, or rapid prototyping.
Pro ($10/month) gives individuals unlimited code completions, access to Copilot Chat, and a baseline allotment of premium model requests. Pro+ ($39/month) raises premium request limits substantially and unlocks the highest-tier models for power users. Business ($19/user/month) adds organization policy controls, SSO, audit logs, and IP indemnification. Enterprise ($39/user/month) layers in knowledge bases grounded on private repositories, fine-grained content exclusions, and custom model integrations.
No. By default GitHub Copilot does not use Business or Enterprise customer code to train foundation models, and individual users can opt out of code snippet collection in their settings. Enterprise plans include contractual guarantees and audit controls covering data handling.
Copilot is officially supported in Visual Studio Code, Visual Studio, the JetBrains family (IntelliJ, PyCharm, GoLand, WebStorm, Rider, etc.), Neovim, Xcode, and Eclipse. It also runs inside the GitHub web editor, the GitHub CLI, and the GitHub Mobile app for chat-style interactions.
Chat answers questions and edits the file you are looking at. Agent mode plans a multi-step task, edits multiple files, runs terminal commands, executes tests, and iterates on errors until the task is complete — all with human checkpoints. The Copilot coding agent goes further by accepting an assigned GitHub issue and producing a draft pull request without an active editor session.
The free tier is a reasonable trial and works for light use, but it caps both code completions and chat messages per month and restricts access to premium models. Developers who use Copilot daily will hit the limits and should expect to upgrade to Pro for unlimited completions.
Now that you know how to use GitHub Copilot Review (2026), it's time to put this knowledge into practice.
