Comparison of Popular AI Code Generation Tools and Their Usage Guidelines

1. Main Efficient Tools

1. GitHub Copilot

Features: Powered by OpenAI, high code generation accuracy, supports multiple languages.

Applicable Scenarios: Rapid prototyping, complex algorithm implementation.

Installation:

Settings → Plugins and search to install, then restart IDEA.

Bind a GitHub account (requires paid subscription, free for students).

Advantages: Strong ecosystem compatibility, abundant community support.

Notes: Requires international network access; enterprises should check code compliance.

2. Amazon CodeWhisperer

Features: Deep AWS integration, excels at generating cloud service code (e.g., Lambda, S3).

Applicable Scenarios: Cloud‑native development, DevOps script writing.

Installation: Enable the AWS Toolkit plugin and log in to an AWS account.

Advantages: Free basic tier, supports CLI command generation.

Notes: Limited usefulness for non‑AWS users.

3. Tabnine

Features: Optional local model, strong privacy protection, fast response.

Applicable Scenarios: Sensitive projects, offline coding environments.

Installation: Install directly from the plugin marketplace; free version is sufficient, Pro version learns from the entire codebase.

Advantages: Low latency, supports 20+ programming languages.

Notes: Free version offers shallow code suggestions.

2. Preferred Tools for Domestic Developers

1. Tongyi Lingma (通义灵码)

Features: Alibaba Cloud product, generates code with Chinese comments, seamless cloud service integration.

Applicable Scenarios: Enterprise development, Alibaba Cloud ecosystem projects.

Installation: Search for Alibaba Cloud AI Coding Assistant in the plugin market and install with one click.

Advantages: Private deployment, enterprise‑level customization, free trial period.

Notes: Requires internet access (except for private deployments).

2. CodeGeeX

Features: Developed by Tsinghua team, completely free, supports code translation and explanation.

Applicable Scenarios: Student projects, cross‑language code migration.

Installation: Install from the plugin market, no login required.

Advantages: Chinese Q&A interaction, suitable for domestic network conditions.

Notes: Generation capability in complex scenarios is weaker than Copilot.

3. Niche but Practical Tools

1. Bito

Features: Based on ChatGPT, supports test case generation, documentation, and code explanation.

Applicable Scenarios: Unit test coverage, technical documentation writing.

Installation: Search in the plugin market and install; requires binding an OpenAI API Key .

Advantages: Directly calls GPT‑4, high flexibility.

Notes: API usage incurs cost; response speed depends on network.

2. Codeium

Features: Free and open‑source, generates code and searches for similar code snippets.

Applicable Scenarios: Open‑source contributions, code reuse optimization.

Installation: Install from the plugin market and register a free account.

Advantages: No paywall, transparent privacy policy.

Notes: Model update frequency is low.

4. Selection Comparison Table

(See the embedded image for a side‑by‑side feature comparison of the tools.)

5. Recommended Combinations

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

Domestic Teams: Tongyi Lingma + CodeGeeX – Chinese support and free, efficient workflow.

Cloud‑First Projects: CodeWhisperer + Tongyi Lingma – cross‑cloud platform code generation.

6. General Installation Steps

Open IDEA → File → Settings → Plugins , search for the desired plugin name, click Install, restart IDEA, then log in or configure the API key as prompted.

7. Precautions

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

Compliance Checks: Enterprises must review generated code to avoid intellectual‑property risks.

Performance Tuning: If memory is insufficient, disable real‑time suggestions in plugin settings.

Choose tools based on project needs and personal preference; start with free options (e.g., CodeGeeX) and upgrade to paid plugins for advanced features.
