IntelliCode is a free Visual Studio feature that improves IntelliSense; GitHub Copilot is a broader generative AI assistant for writing, explaining, testing, and debugging code. They overlap in inline suggestions, but they are not equivalent alternatives—and Visual Studio supports using them together. Choose IntelliCode for lightweight, local completion help at no extra cost. Consider Copilot when you want to ask for code in natural language or get conversational help across development tasks.
At a glance
| Need | Better fit | Why |
|---|---|---|
| Rank likely methods and members in Visual Studio | IntelliCode | It enhances the normal IntelliSense completion list. |
| Basic whole-line suggestions without another subscription | IntelliCode | It is included with most supported Visual Studio workloads and its whole-line predictions run locally. |
| Generate a function from a description | Copilot | It can produce multi-line code from prompts and context. |
| Ask questions, explain code, or get help debugging | Copilot Chat | It offers conversational assistance; IntelliCode does not provide general coding chat. |
| Work offline or in an air-gapped environment | IntelliCode, for whole-line completion | That feature can run locally. IntelliCode API examples are a separate web-backed feature. |
| Use assistance across several IDEs | Copilot | It is available in Visual Studio and multiple other development environments, though feature availability varies by IDE. |
| Get both ranked IntelliSense and generative help | Use both | Microsoft documents them as compatible, complementary features. |
There is no evidence-based universal winner for suggestion quality. The useful distinction is the work each tool does: IntelliCode helps you choose or continue code while editing; Copilot can generate and discuss code at a larger scale.
What IntelliCode does
Visual Studio IntelliCode is an enhancement to IntelliSense, not a separate general-purpose chatbot. It uses coding context to rank likely completion choices, placing starred suggestions near the top. Depending on the language and feature, it can also complete arguments, show whole-line predictions in gray text, suggest repeated edits in C#, and surface API usage examples.
Microsoft lists C#, XAML, C++, JavaScript, TypeScript, and Visual Basic for IntelliCode in Visual Studio. JavaScript and TypeScript support has a documented TypeScript 3.4.2-or-later requirement. Capabilities are not necessarily identical across languages: check the IntelliCode documentation for the feature and language you use.
#1 Best Overall
IntelliCode is free as a Visual Studio feature and is included by default with most supported workloads. That does not make Visual Studio itself free in every case: Visual Studio Community, Professional, and Enterprise have separate licensing terms. See Visual Studio’s pricing and edition details.
What Copilot adds
GitHub Copilot is a cloud-connected AI coding assistant. In Visual Studio it can suggest lines and blocks, generate implementations from natural-language comments or function signatures, and provide chat assistance for tasks such as explaining code, proposing tests, and helping investigate a problem. Other Copilot capabilities—such as agents, cloud agents, code review, or CLI assistance—depend on the plan and where you use Copilot. Do not assume every capability available on GitHub.com or in another IDE is available in Visual Studio.
Microsoft documents support in Visual Studio 2022 version 17.8 or later. Version, plan, rollout, and preview settings can affect the interface and features you see. Copilot also works in other environments, including Visual Studio Code and several JetBrains IDEs; GitHub’s plan documentation describes supported surfaces and plan-dependent access.

Completing a familiar C# API call
If you know the object or library and need help finding the right member, IntelliCode’s ranked IntelliSense suggestions are a natural fit. It can make a likely method or property easier to spot without asking a separate question. Its API usage examples can provide examples for recognized functions from public GitHub repositories.
Creating a new endpoint or function
Copilot is the more capable option when you can describe the behavior and want a multi-line starting point. For example, you might ask it to draft a C# endpoint with input validation or write a parser for a specified format. Treat the result as a proposal: confirm the project’s conventions, dependencies, error handling, and edge cases before accepting it.
Generating tests or explaining unfamiliar code
Copilot Chat can help draft tests or explain a selected section of code. IntelliCode can improve completions while you write tests, but it does not replace a conversational explanation or test-generation workflow. Generated tests still need review: check that they verify meaningful behavior rather than merely matching the implementation.
Debugging a failure
Copilot Chat can help reason about an error message, a failing test, or a possible fix. It cannot guarantee that it has enough context to diagnose the cause, and a suggested change may mask a symptom or introduce another defect. Reproduce the issue, inspect diagnostics, run relevant tests, and review the diff. IntelliCode has no comparable conversational debugging workflow.

IntelliCode can detect repetitive edits and suggest applying a similar action elsewhere in C#. Microsoft’s Visual Studio comparison also lists repeated-edit assistance for Copilot. Exact behavior can differ by release, so check the current Visual Studio feature description rather than treating the labels as identical implementations.
Working without network access
Microsoft says IntelliCode whole-line completions run on the local machine and can work offline, including in air-gapped settings. That qualification applies to the whole-line feature, not every IntelliCode capability: API usage examples use a web service and may not be available on a restricted network. Copilot should be treated as requiring GitHub authentication, service connectivity, and organizational approval. Confirm current proxy and firewall requirements with GitHub before deployment.
Privacy and organizational controls
Do not reduce this comparison to “IntelliCode is private” versus “Copilot sends everything.” The features have different data paths, and Copilot handling depends on the feature, IDE, plan, account type, settings, and organizational terms.
- IntelliCode whole-line completion: Microsoft says predictions run locally and your code is not sent to Microsoft to make them.
- IntelliCode API usage examples: This capability contacts a web service for examples associated with recognized functions. Microsoft says the code check is performed locally and your code is not sent over the internet for that purpose. The documented service domain is
*.intellicode.vsengsaas.visualstudio.com. - Copilot: It is a cloud-connected service. Review GitHub’s Copilot data privacy documentation, Copilot Trust Center, and applicable organizational settings and agreements. GitHub states that individual subscribers can opt out of use of their data for AI model training through Copilot settings. Do not assume that one retention or training rule applies to every plan and feature.
If your organization prohibits sending coding context to a cloud service, get security and legal approval before enabling Copilot. A business or enterprise plan may offer centralized management and policy controls, but a plan label alone does not settle whether a particular workflow is approved.
Price and free access
IntelliCode has no separate subscription. Copilot has free and paid plans, but “free” does not mean unlimited or equivalent to IntelliCode. GitHub’s public pricing page and plan documentation may display different detail as allowances and offerings change. The table below reflects the dossier’s August 16, 2026 pricing snapshot; confirm current prices, quotas, eligibility, and availability on the official Copilot plans page before buying.
Best Value
| Copilot plan | Snapshot price | Typical consideration |
|---|---|---|
| Free | $0 | Limited usage and feature access; not an unlimited substitute for a paid plan. |
| Student | Free for verified students | Eligibility and access depend on verification. |
| Pro | $10 USD/month | Individual developers who want broader, regular Copilot use. |
| Pro+ | $39 USD/month | Individuals who need more premium-model access or usage allowance. |
| Max | $100 USD/month | High-volume individual use; likely unnecessary for basic completion needs. |
| Business | $19 USD per granted seat/month | Organizations seeking centralized licensing and policy management. |
| Enterprise | $39 USD per granted seat/month | Eligible enterprises seeking additional enterprise capabilities and management. |
GitHub’s documentation reported a temporary pause beginning April 22, 2026, on new self-serve Copilot Business sign-ups for some organizations. Microsoft’s Visual Studio documentation reported Copilot Pro trial pauses as of April 20, 2026. These are time-sensitive availability notes, not permanent plan rules; check the live plan pages. Microsoft also documents special Copilot Free behavior in Visual Studio: under certain conditions, IntelliCode suggestions may appear instead of Copilot completions, and some account categories are not eligible for that Free path. See Microsoft’s Copilot Free in Visual Studio documentation.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Can you use IntelliCode and Copilot together?
Yes. Microsoft explicitly presents the tools as usable together. IntelliCode can continue to enhance the IntelliSense list, while Copilot provides generative completions and chat. Keep both if you find the ranked API suggestions useful and also want help drafting larger pieces of code. If overlapping predictions feel noisy, adjust or disable the relevant completion behavior in Visual Studio rather than assuming one product must replace the other.
Which should you choose?
- Choose IntelliCode first if you mainly want ranked API/member suggestions, argument completion, or local whole-line predictions in Visual Studio and do not need chat or code generation.
- Consider Copilot if you regularly want to turn descriptions into code, draft tests, ask questions about code, or get conversational debugging help. Compare the current plan limits with your actual usage before subscribing.
- Use both if you value IntelliCode’s low-friction IntelliSense improvements and Copilot’s broader assistance. They address different parts of the workflow.
- For offline or regulated work, validate the exact feature’s network and data behavior against organizational policy. IntelliCode whole-line completion has a documented local mode; Copilot requires service access and approval.
- For teams, evaluate identity, policy, procurement, data handling, and IDE-specific feature availability—not just seat price.
Whichever tool you use, generated code is not verified code. Check licenses and dependencies as appropriate, inspect the changes, run tests and static analysis, and use your normal security review. Faster initial typing can still mean more review or debugging work; neither tool guarantees productivity gains or correctness.
Set up and troubleshoot in Visual Studio
Verify IntelliCode
- Open Visual Studio Installer and confirm that a supported workload is installed.
- In Visual Studio, check Extensions > Manage Extensions for IntelliCode and confirm it is enabled.
- Review Tools > Options for IntelliCode and code-completion settings if starred suggestions or gray whole-line predictions are missing.
- For whole-line suggestions, Microsoft documents Tab to accept and Esc or Delete to dismiss in supported scenarios.
- If suggestions still do not appear, temporarily disable competing completion extensions and verify the language feature is supported.
Verify Copilot
- Confirm Visual Studio 2022 is version 17.8 or later.
- Sign in with the GitHub account that has the eligible Copilot access; check that the account or organization has not blocked the feature.
- Install or enable the Copilot components offered by your Visual Studio version, then restart Visual Studio if access or installation changed.
- Open a supported code file and test inline completion. Open Copilot Chat only if it is available for your version and plan.
- If it fails, check plan eligibility, organization policy, network/proxy/VPN and certificate rules, file type, preview status, and conflicts with other AI or completion extensions.
For current setup instructions, use Microsoft’s Visual Studio AI assistance guide and GitHub’s Copilot quickstart.
