ChatGPT Complete Guide 2026

From Start to Finish — by Ellis Trent

ChatGPT changed a great deal in 2026. There are new GPT-6 models, new plans, adverts on the free tier in the UK, Canvas replaced by writing blocks, and a Work agent that can deliver finished reports and presentations. This plain-English guide shows you how to get real value from it, whether you are opening it for the first time or already use it every day.

Written for UK readers and checked against official sources in October 2026, it covers:

• Setting up your account and the settings to change on day one
• Every plan explained, from Free and Go to Plus, Pro and Business, so you can choose wisely
• A clear tour of the interface, model picker and writing blocks
• Prompting that works, with dozens of worked examples you can copy and adapt
• Projects, memory, search, deep research, voice, images, study mode, Work and Codex
• Practical uses for writing, work, study, small business and home life
• Privacy settings, safety habits and honest limitations
• Troubleshooting, a glossary and official resources

There's no hype and no jargon, just warm, practical guidance in 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.
