## FAQ

**Is it safe to use AI coding assistants with proprietary code?**

It depends on the provider. Enterprise-focused tools like GitHub Copilot for Business, Tabnine, and Amazon Q Developer (formerly Amazon CodeWhisperer) have strict policies against retaining or training on your code. Many offer additional security features like private endpoints. Always review the provider's data handling policies and choose one that meets your organization's compliance requirements.

**Which AI coding assistant is best for Python?**

GitHub Copilot is widely regarded as excellent for Python due to the language's vast representation in its training data. However, Tabnine also performs exceptionally well and offers strong personalization, while Amazon Q Developer (formerly Amazon CodeWhisperer) has an edge for Python development within the AWS ecosystem (e.g., for Lambda functions).

**Can AI coding assistants write entire applications?**

No, not yet. AI coding assistants are powerful tools for augmenting a human developer, not replacing them. They excel at generating boilerplate code, writing well-defined functions, creating unit tests, and suggesting solutions to localized problems. They cannot handle high-level system architecture, complex logic spanning multiple files, or understanding business requirements.

**How much do AI coding assistants cost?**

Prices typically range from free for individual tiers to around $10-$20 per user per month for professional or team plans. Enterprise plans with advanced security and management features are usually custom-priced and can be significantly higher.
