The honest paragraph about how it works
Claude is made by Anthropic, an AI company founded by former OpenAI researchers. Under the hood it works on the same foundation as ChatGPT: it was trained on an enormous amount of text, and it produces answers by predicting what words should come next. That one sentence explains both the magic (it has absorbed more writing than any human ever could) and the mistakes (it's predicting, not looking things up — so it can be confidently wrong).
Same machinery, different personality. Where ChatGPT tends toward fast, eager, and list-shaped, Claude tends to write in sentences that sound like a thoughtful person, hedge honestly when it isn't sure, and stay composed across very long conversations and very long documents. Nobody fully agrees on why the personalities differ — training choices, mostly — but the difference is real enough that you'll feel it within a day.
When women in business reach for Claude
Across the Prompt Queen community, three jobs come up again and again as "this is why I keep Claude open":
- Long-form writing that needs to sound human. Newsletters, about pages, sales pages, blog posts. Claude's first drafts need less de-robotifying than any other tool's — and with the voice setup in Lesson 2, sometimes none.
- Thinking through fuzzy decisions. "Should I raise my prices?" "Which of these three offers do I build first?" Claude is unusually good at holding a messy, human problem and pushing back respectfully instead of cheerleading.
- Reading big documents. Hand it a 40-page contract, a podcast transcript, or the entire text of your website, and ask it questions. This is Claude's superpower — long inputs are its home turf, not a strain.
The rules that don't change
Everything you learned about AI safety in ChatGPT Basics carries straight over. Three rules, non-negotiable:
- Never publish a fact it gave you without checking. Claude hallucinates less dramatically than most, but "less" is not "never." Names, numbers, dates, quotes, legal and medical claims: verify.
- Never paste in anything you'd be upset to see leaked. Client SSNs, unreleased financials, other people's private information — keep them out of any AI tool.
- You are the editor. AI multiplies your judgment; it doesn't replace it. If a draft is 80% there, that last 20% — the taste, the truth, the you — is your job and your value.
Plans and money: what you actually need
Verified July 2026. Prices and limits are the fastest-moving part of any AI product — concepts below will hold, but glance at claude.com/pricing before paying for anything.
| Plan | Price | What you get | Who it's for |
|---|---|---|---|
| Free | $0 | Claude's everyday model (currently Sonnet), web search, memory, Artifacts, file uploads, up to 5 Projects. Usage limits that reset on a rolling basis. | Everyone starts here. Everything in this course works on Free. |
| Pro | $20/mo | Much higher usage limits, access to the most capable models, early access to new features. | You've hit the free limits more than twice in a week — that's the signal. |
| Max | $100–200/mo | 5×–20× Pro usage. | Heavy daily users running AI all day. Not you yet, and maybe never. |
Start free. Do the whole first week (Lesson 6) on the free plan. If you find yourself rationing messages — saving Claude conversations for "important" work the way you'd save nice stationery — that's when $20/month pays for itself. It buys you the freedom to think out loud.
A word about models
Inside Claude you'll see a model picker with names like Sonnet, Opus, and Fable. Think of them as engine sizes: the default free model (Sonnet) is genuinely excellent and handles everything in this course; the premium models on paid plans think more deeply on hard problems and write with a bit more grace. Don't overthink this. The default is fine, the names change every few months, and no model choice matters as much as the quality of your prompt.
Where to use it
Claude lives at claude.ai in any browser, plus mobile apps (iOS/Android) and a desktop app. Start in the browser — the walkthroughs in Lesson 2 assume it. One account, everything syncs.
Claude now has a memory feature: it can remember facts about you and your work across conversations (you can view, edit, or turn this off in Settings). Useful — but don't rely on it as your system. The Project you'll build in Lesson 2 is deliberate, inspectable context you control. Memory is a nice-to-have on top.
Open claude.ai in a new browser tab and create a free account. That's the whole assignment for Lesson 1 — you'll need it open for every lesson that follows. This course works best as a do-along, not a read-through.
