AI Assistant

Codex and Claude, right inside Visual Studio.

Work with your AI assistant from a dedicated sidebar in Visual Studio 2022 and 2026. Ask questions, make changes, and review the results without leaving your IDE.

• Your account, your models. Connect your existing Codex or Claude Code account and choose your model and reasoning effort.
• Context that matters. Work with project files and optionally include your active editor file or selected code.
• Files and images. Attach references, screenshots, and documents to your requests.
• Conversations that stay with you. Save, search, and continue previous chats.
• Review changes clearly. Open changed files in Visual Studio’s native diff editor.
• Stay in control. Choose permissions, queue follow-ups, and steer an active Codex response.
• Follow delegated work. View Codex agents and their activity from the sidebar.

The sidebar opens on first use. You can reopen it anytime from View > AI Assistant.

Requires access to Codex or Claude Code. Available models, features, and usage limits depend on your provider and account.
