AI Systems Playbook

You don’t use one knife for everything in the kitchen. So why are you still using one AI for everything in your work?ChatGPT for the email. Claude for the long-form draft. Perplexity for the research. Gemini in your Google Docs. Copilot in your enterprise tenant. Most working people now have access to four or five AI assistants - and almost no idea which one to use when.That confusion is expensive. You write the same prompt in three tabs to compare answers. You pay for overlapping subscriptions. You hand off work between tools and lose half the context every time. You pick the wrong AI for the job and blame the technology when it underperforms.AI Systems Playbook is the book that makes the multi-AI world legible. Instead of going deep on a single product, this book goes wide: it teaches you which AI is genuinely best at each kind of work, how to chain them together into reliable workflows, and how to build a personal AI strategy that survives the next round of model launches.What’s inside:The landscape, mapped honestly. What’s out there in 2026, how these tools actually work under the hood, and the differences between the major players (ChatGPT, Claude, Gemini, Perplexity, Copilot, and the rest) that actually matter for your work.Head-to-head, by use case. Eight chapters of opinionated, hands-on comparisons - writing, research, data analysis, coding, creative work, business and professional use, education and learning. For every task, a clear 'reach for this one first' recommendation, with the reasoning behind it.Cross-AI workflows. This is where the real power lives. Multi-AI workflow design. The art of the handoff between tools without losing context. Managing your AI toolkit so the subscriptions earn their keep. Privacy and data flow across platforms. Prompt portability when you switch.The deeper layer. Custom assistants across platforms (Custom GPTs, Claude Projects, Gemini Gems), AI baked into the tools you already use (Microsoft 365, Google Workspace, Notion, Slack), and mobile and on-the-go AI patterns.Strategy, not just tactics. What to do when AI gets it wrong. How to build your personal AI strategy. How to evaluate the next wave of platforms without rewriting your whole approach.Comparison tables, workflow templates, and a full glossary in the appendices - designed for quick reference long after the read-through.If you are tired of hopping between tabs hoping the next AI will give you the answer the last one missed, this book replaces the chaos with a system.Includes coverage of GPT-5, Claude Sonnet 4.6 / Opus 4.7, Gemini 3, Perplexity Sonar, Microsoft Copilot, and the cross-platform integrations that matter in 2026.
