Chapter 4
The Field Guide
By now you can run a good conversation (Chapter 2), and your Skeleton Key's in your pocket (Chapter 3). What's missing is the lay of the land — because new tools arrive roughly weekly, usually introduced by someone slightly too excited, and "panic" and "ignore it forever" can't be your only two settings.
Here's the mercy: there are not forty things to learn. There are five.
Five categories. Most tools sit squarely in one; the show-offs do two. Either way, once you know the five, you can place a brand-new tool on the map before you even open it — the famous ones, the one your brother-in-law swears by, the one your company bought a licence for without telling anyone how to use it. You stop choosing by which brand is shouting loudest this quarter, and start choosing by the kind of job actually sitting in front of you.
Match the type to the task
| Category | Examples | Open it when |
|---|---|---|
| Big general assistants | ChatGPT, Claude, Gemini, Copilot | Drafting, planning, explaining, summarizing — most of your everyday work |
| Specialists | Perplexity, NotebookLM, Grammarly, note-takers | One thing, done well — sourced research, your own documents, polishing |
| Visual tools | Canva AI, image generators | The output is meant to be seen — a graphic, a slide, an image |
| Power tools | Codex, Claude Code | Real files, websites, actual code — bring guardrails |
| The advanced stuff | Agents & automations | Later — when AI stops just answering and starts acting in your accounts |
Pick the wrong category and you don't get a slightly worse result — you get one you can't use at all. It's like sending someone to Blockbuster for date night and having them come home with a three-hour WWII documentary. Technically, they grabbed a movie. You're still not watching it.
How to choose
So how do you actually pick? Lazily, on purpose. Start almost everything in a big general assistant — it's the Swiss Army knife, and most of your week is exactly what it's built for. You only reach past it when it visibly hits a wall: when you need real sources you can click, when it has to reason over your own files, when the thing has to be seen, or when it needs to touch real files and code (and yes — a tool that can change real files can break real ones, which is the entire "bring guardrails" warning in five words). Default to the generalist. Graduate only when it fails in front of you.
Here's the whole rule in a single task. Three messy call notes into a clean board summary — general assistant, done before your coffee's cold. The same summary, except now it has to quote your privacy policy word-for-word from the actual document — that's the wall, and that's the moment you reach for a specialist that reads your files instead of guessing at them.
That's the entire point of a field guide. You don't have to know every bird. You just have to clock whether you're looking at a hawk or a pigeon before it gets close enough to matter.
Tool cards
Tool cardsThe ChatGPT card is up first. Claude, Gemini, Copilot, Perplexity, and NotebookLM are in the queue and will land here as they ship — one card per tool, so the moment you're ready to actually meet one, the introduction's already written.
