Chapter Six: Picking Your Rig — The Big Dummy's Guide to AI

The old CB guides spent a whole chapter on choosing a radio, because a bad rig was forty wasted dollars. Here's the modern miracle: every AI on this page is free to try and switching takes ten seconds. So relax — this is the lowest-stakes shopping trip of your life.

The three big rigs on the shelf

Think Ford, Chevy, Dodge. All three get you down the road; they differ in personality, not in whether they work. All three have free versions, phone apps, and websites. Here's the honest folk wisdom on each:

Claude

claude.ai · made by Anthropic. The careful, thoughtful one — shines at long documents, writing that sounds human, and explaining things patiently. If you bring it a 12-page insurance policy, it reads the whole thing.

the careful one

ChatGPT

chatgpt.com · made by OpenAI. The famous one your grandkids mention — the household name with every bell and whistle: pictures, voice, the works. The biggest crowd is on this channel.

Gemini

gemini.google.com · made by Google. The connected one — if your life already runs on Gmail, Google Calendar, and an Android phone, it plugs into all of it.

Can't decide? Use this rule: heavy reading and letters → Claude. Want what everyone else has → ChatGPT. Married to Gmail → Gemini. Still stuck? Start with any one of them today and try a different one next week. They don't get jealous.

Free or paid? (Don't reach for your wallet yet)

Start free. Stay free for at least a month. The free versions are the same machines with a daily limit — like a phone plan with capped minutes. Most beginners never hit the cap.
You'll know it's time to pay when you hit the wall twice in one week — a message saying you've used today's allowance. If that keeps happening, you're a real user now, and the ~$20/month tier removes the wall.
Never pay anyone except the company itself. Upgrades happen inside the official app or website only. Anyone else selling "AI access" — a phone call, an email, a Facebook ad — is a scam, full stop. (More in Chapter Eight.)

The test drive

Take whichever one you picked around the block with these three errands — they'll show you its personality fast:

"Explain Medicare Part D like I'm brand new to it." Tests how clearly it teaches.
"Here's what's in my fridge: [list it]. Give me three dinner ideas." Tests practical everyday help.
"Write a short, warm thank-you note to my neighbor for bringing in my trash cans." Tests whether its writing sounds like a person or a robot.

If the answers feel right to you, that's your rig. Personal taste is the whole ballgame — same as it ever was with radios.
