ChatGPT

ChatGPT has changed everything. This book makes sure you don't miss any of it.

ChatGPT is the most widely used AI tool in the world - but most people are only using a fraction of what it can do. They type a question, get an answer, and move on. They don't know about Agent Mode, Deep Research, Projects, Canvas, Study Mode, or the dozens of other features that transform ChatGPT from a clever chatbot into a genuine productivity platform.

This book changes that.

ChatGPT: The Definitive Guide is the comprehensive, up-to-date guide to everything ChatGPT can do in 2026. Written for real people - not developers, not AI researchers - it covers every feature, every plan, and every practical use case in plain English.

What's inside:

• Get started right. Choose the right plan (Free, Go, Plus, Pro, Business, or Enterprise), set up your account, understand the GPT-5 model family, and have your first productive conversations.
• Master the core skills. Writing, research, everyday productivity, and professional use - with concrete walkthroughs you can follow along with.
• Unlock every feature. Image generation with DALL-E. Video with Sora. Collaborative editing with Canvas. Voice conversations. Data analysis. Web search. Agent Mode. Tasks and automation. Projects. Custom GPTs. Connectors. Memory. The Atlas browser. Every tool, explained and demonstrated.
