AI Coding Assistants Guide 2026

Cursor, Copilot & Claude Code — by Ellis Trent

AI can now read your codebase, plan a change, edit dozens of files and run the tests. Used well, it makes experienced developers dramatically faster and makes programming approachable for everyone else. Used carelessly, it ships bugs and leaks secrets. This guide shows you the right way.

Checked against official documentation in October 2026, it covers:

• Choosing and installing the leading tools, including the current Claude Code installer
• Up-to-date plans and pricing, including the new bundled subscription for the AI editor and the credit-based plans
• Interface tours with keyboard shortcuts, agent modes and terminal commands
• Prompting for code, with worked examples for understanding, planning, debugging, testing and review
• A safe workflow built on Git and the review loop
• Project rules and context files, cloud agents, code review bots and MCP
• Real uses for professional work, learning to code, small business websites and scripts
• Security, privacy, licensing and the risks of agents

For working developers, students, career-changers and non-programmers who want to build useful things, in plain British English.

What you get: an instant digital download in two formats, PDF and EPUB, so you can read on any computer, tablet, phone or e-reader. First edition, October 2026, written in British English.
