Requirements Before Enabling Copilot Code Review
GitHub Copilot automatic code reviews require an active subscription: Copilot Pro ($10/month for individuals) or Enterprise plans for organizations. Repository administrators need permissions to configure rulesets, and organization owners must enable preview features to access code review functionality.
The 2026 update introduced AI review queue prioritization, which helps teams manage review workloads more effectively. GitHub supports both public and private repositories across GitHub Free, Pro, Team, and Enterprise Cloud plans.
How to Turn On GitHub Copilot Code Review
Method 1: Personal Settings for Individual Developers
Start with your personal settings if you want Copilot to review your own pull requests. Click your profile photo in the top-right corner, select “Your Copilot,” then toggle “Automatic code review by Copilot” to Enabled. This setting applies to all your pull requests across repositories where you have access.
This personal configuration gives you automatic Copilot reviews quickly and does not require any administrative permissions. It works well for individual contributors who want consistent AI feedback on every pull request.

Method 2: Repository Rulesets for Project-Level Control
Use repository rulesets when you want automatic reviews for a specific project. Go to Settings > Rules > Rulesets > New branch ruleset. Name your ruleset, such as “Copilot Auto Review,” select target branches, then enable “Automatically request Copilot code review.”
The September 2025 update introduced independent repository rules, which allow automatic reviews without enforcing pull request requirements.
Configure subsettings based on your workflow:
- “Run on each push” reruns reviews when new commits are added.
- “Run on drafts” triggers reviews for draft pull requests.
These options let you decide how often Copilot reviews your changes and whether it should comment on work-in-progress branches.

Method 3: Organization and Enterprise Rulesets at Scale
Organization owners can roll out automatic reviews across many repositories using organization rulesets. Open Organization Settings > Rulesets > New ruleset, then select target repositories and branches and enable the Copilot code review rule.
This method keeps review coverage consistent across multiple repositories while still allowing granular control over which projects receive automatic reviews. It suits larger teams that want a standard review policy across products.

Customizing GitHub Copilot Code Review Instructions
Create a .github/copilot-instructions.md file in your repository to customize review behavior. Example instructions include “Prioritize security vulnerability detection,” “Focus on performance optimizations,” or “Ignore minor style preferences.”
Instructions cannot perform tasks outside code review scope. They cannot block pull request merges or modify product behavior and only guide how Copilot comments on code.

Copilot Code Review Troubleshooting Tips
Most issues come from permission conflicts or misaligned rulesets. Permissions errors often appear when branch protection rules conflict with rulesets, so verify that your ruleset scope matches the target branches.
Confirm that pull requests are in the correct state, and remember that drafts only trigger reviews if you enabled draft support. The independent repository rule update resolved many triggering issues by separating reviews from strict pull request requirements.
Where GitHub Copilot Code Review Falls Short
GitHub Copilot automatic code reviews provide suggestions but do not implement fixes, so developers must apply changes and validate them manually. Benchmark studies show Copilot frequently fails to detect critical vulnerabilities like SQL injection and XSS and often focuses on low-severity style issues.
Only about 30% of AI-suggested code gets accepted, which limits the impact of Copilot reviews on real-world code quality. The system also becomes unreliable on large pull requests with 1,000 or more files, where coverage and accuracy drop.
| Capability | Copilot | Competitors | Gitar |
|---|---|---|---|
| Auto-fixes | No | No | Yes (free trial) |
| CI Integration | No | Limited | Full validation |
| Pricing | $10-30/mo | $15-30/mo | Free review |
| Large PR Support | Unreliable | Limited | Enterprise scale |
Why Upgrade to Gitar for AI Code Review
Gitar moves beyond suggestions and automatically fixes CI failures, implements review feedback, and validates changes against your build system. The platform offers unlimited free code review with a 14-day auto-fix trial and supports teams from startups to enterprises processing more than 50 million lines of code daily.
Setup takes about 30 seconds. Visit https://gitar.ai/ and install the GitHub App. Gitar consolidates all findings into a single, updating dashboard comment, which reduces notification noise while still providing comprehensive analysis.
Unlike suggestion-only tools, Gitar’s healing engine validates that fixes work before committing them. This approach prevents broken builds from reaching main branches and saves developers from repeated fix-and-retry cycles.
For a 20-developer team, manual CI and review issues cost roughly $1M annually in lost productivity. Gitar’s auto-fix capabilities reduce this burden by automatically resolving lint errors, test failures, and build breaks, often before developers even notice the issues.
Companies like Pinterest trust Gitar with enterprise-scale repositories, and teams report that Gitar’s pull request summaries are “more concise than Greptile/Bugbot” because of the single-comment approach. The platform integrates with existing workflows through natural language rules and avoids complex YAML configuration files.

Enterprise plans add features like organization-wide policies and advanced security controls, while Pro covers the core automatic review functionality.
Can I use GitHub Copilot code review in VSCode?
GitHub Copilot code review runs at the pull request level on GitHub.com, not inside IDEs like VSCode. The feature analyzes entire pull request diffs and posts feedback through the GitHub web interface.
IDE-based Copilot features still handle code completion and inline suggestions separately from pull request reviews.
How do I enable automatic reviews for all pull requests?
Use repository rulesets in Settings > Rules > Rulesets to trigger Copilot reviews on all matching pull requests. Configure the ruleset scope to target specific branches and enable the “Automatically request Copilot code review” option.
Adjust subsettings such as “Run on each push” and “Run on drafts” to match how your team works with feature branches and early feedback.
What is the difference between Copilot and Gitar for code reviews?
Copilot provides suggestions and comments but requires manual implementation of fixes. Gitar automatically implements fixes, validates them against CI, and delivers working solutions.
