Advantages: Free basic tier and supports CLI command generation.

Note: Limited usefulness for non‑AWS users.

Practical effect:

Tabnine

Features: Offers a local model option, strong privacy protection, fast response.

Applicable scenarios: Sensitive projects and offline development environments.

Installation: Install directly from the IDE plugin marketplace; the free version is sufficient for most use cases, while the Pro version can learn from the entire codebase.

Advantages: Low latency; supports 20+ programming languages.

Note: The free version provides shallower code suggestions.

Practical effect:

Preferred Domestic Tools

通义灵码 (Tongyi Lingma)

Practical effect:

Selection Comparison Table

Recommended Tool Combinations

Individual developers: GitHub Copilot + Bito – high‑precision generation plus documentation/test coverage.

Domestic teams: Tongyi Lingma + CodeGeeX – Chinese support and free, efficient assistance.

Cloud projects: Amazon CodeWhisperer + Tongyi Lingma – cross‑cloud code generation.

Common Installation Steps

Open IDEA → File → Settings → Plugins.

Search for the desired plugin name and click Install .

Restart the IDE, then log in or configure the required API Key as prompted.

Important Considerations

Network issues: International plugins (e.g., Copilot) need stable external access; domestic plugins connect directly.

Compliance check: Enterprises should review generated code to avoid intellectual‑property risks.

Performance tuning: If memory is limited, disable real‑time suggestions in plugin settings.
