Features

Codeium provides rich features: code completion (single-line, multi-line, whole-file), AI chat, code explanation, refactoring suggestions, documentation generation, test generation, and more. It supports context awareness, understanding the entire project structure. It provides a command palette for quickly executing AI operations.

Configuration

Codeium provides rich configuration options, allowing you to adjust completion behavior, shortcuts, models, privacy, and more. It supports project-level configuration, so different projects can use different settings.

# Global configuration

  "codeium.telemetry": false,
  "codeium.enterpriseMode": false
}

Chat

Codeium Chat provides a conversational AI assistant. You can ask code questions, generate code, explain logic, debug issues, and more. Chat supports code context, allowing you to reference the current file, selected code, and more. Chat history can be saved and searched.

# Use Chat
# Shortcut: Ctrl+Cmd+C (Mac) / Ctrl+Alt+C (Windows)

# Example conversations:
# User: "Explain what this function does"
# User: "Add unit tests for this class"
# User: "How to optimize this SQL query?"

Command

Codeium Command is an AI command feature that can execute operations via natural language. Enter a description, and Codeium will generate the corresponding code or perform the operation. It supports multiple operations such as refactoring, generation, and transformation.

# Use Command
# Shortcut: Ctrl+Cmd+I (Mac) / Ctrl+Alt+I (Windows)

# Example commands:
# "Convert this function to async/await"
# "Add error handling"
# "Generate TypeScript types"

Enterprise
