Frequently asked questions

How much should I expect to pay for an AI coding assistant?

Many tools offer free tiers sufficient for hobbyist and individual developers, including GitHub Copilot free, Gemini Code Assist free, Amazon CodeWhisperer free, and JetBrains AI Assistant free. Paid tiers typically range from £9-20 per month for individual developers, with enterprise plans reaching £19-59 per user per month for teams with compliance requirements.

Which AI coding assistant works best with my existing editor?

GitHub Copilot offers the broadest editor support, working natively with VS Code, JetBrains IDEs, Neovim, Emacs, and more. JetBrains AI Assistant integrates natively into all JetBrains products. If you prefer a new IDE, Cursor and Windsurf are purpose-built, AI-first environments.

What if my organisation has strict data privacy requirements?

Tabnine supports fully air-gapped on-premises deployment with zero external connectivity, ideal for regulated industries. Alternatively, Cline is open-source and runs entirely client-side, meaning code never leaves your machine. Both options prioritise data security over cloud convenience.
