CppPilot

Codex-powered C++ workflows, directly inside Visual Studio.

CppPilot brings build diagnostics, Git reviews, native crash analysis, and a persistent development chat together in one Visual Studio extension. It uses the Codex CLI installed on your computer and your existing Codex authentication, so you can investigate and correct problems without leaving the IDE.

Fix C++ build errors

Turn Visual Studio build diagnostics into focused corrections:

• Open the same error workspace from the Error List, the latest Build output, or a CppPilot build command.
• Review every detected compiler, linker, or MSBuild error on one page.
• Fix a single diagnostic with its dedicated Fix button.
• Use Fix all errors for a progressive, multi-pass correction.
• Automatically rebuild the relevant C++ project when Visual Studio can determine the build scope.
• Follow each error through its ready, correcting, verifying, resolved, or still-present state.
• Open supported source, project, .props, and .targets locations directly.

CppPilot supports common MSVC diagnostics such as Cxxxx, LNKxxxx, and MSBxxxx errors.

Review changes before committing

Run Review with CppPilot directly from the Visual Studio Git Changes window. CppPilot examines staged, unstaged, and untracked changes with repository context, then presents concise findings with clickable file and line references.

When a review identifies an actionable issue, you can ask Codex to correct the findings using a dedicated fix action. You can also review the current file, the changes in the current file, or a branch against its detected parent branch.

Analyze native crashes

When Visual Studio breaks on a supported native exception, assertion, or debug break, CppPilot can display a non-modal analysis notification. The analysis uses bounded debugger context, including the active location, call stack, arguments, and local variables, to help identify the likely root cause.

Crash analysis starts in read-only mode. You remain in control and explicitly choose whether Codex should apply a proposed correction. Notifications can be disabled directly from the notification or from CppPilot settings.

Chat with project context

Use the persistent Codex chat to explore code, ask technical questions, investigate logs, or implement a feature in the current workspace.

• Resume conversations across Visual Studio sessions.
• Attach source files, text files, logs, and images with the file picker.
• Drag files from Windows Explorer directly into the chat.
• Paste images from the clipboard.
• Cancel long-running operations and follow compact progress updates.

Choose your language and model

CppPilot follows the Visual Studio interface language by default. The interface is available in:

• English
• French
• German
• Italian
• Spanish

Unsupported languages fall back to English, and a manual language override is available in settings.

You can use the model selected by your local Codex configuration, choose a model available to your signed-in account, or enter an exact model ID. The selected model is used by CppPilot operations and resumed chats.

Safety, privacy, and control

• Analysis workflows run in the Codex read-only sandbox.
• File modifications require an explicit fix action.
• CppPilot runs your locally installed Codex CLI with your own authentication and configuration.
• Code and context required by an operation may be transmitted by Codex CLI to OpenAI.
• Optional CppPilot telemetry is disabled by default.
• Telemetry never includes source code, prompts, responses, file paths, build output, Git data, images, debugger data, account identifiers, or authentication tokens.

CppPilot is open source and distributed under the MIT License.

Requirements

• Visual Studio 2022 or later with the MSVC C++ x64/x86 build tools.
• For Visual Studio 2019, install the separate CppPilot for Visual Studio 2019 package.
• A compatible Codex CLI installation, authenticated with codex login.
• Git for Git review features.

CppPilot can detect compatible Codex installations from your system and lets you select a specific codex.exe from its settings when needed.

Get started

1. Install the CppPilot VSIX that matches your Visual Studio version.
2. Open Extensions > CppPilot > Home.
3. Verify the detected Codex CLI installation in Codex Settings.
4. Open a C++ solution and choose a build check, Git review, crash analysis, or Codex chat workflow.
