Who it is for
For anyone tired of paying for a dozen AI subscriptions and unsure which tool actually fits the job in front of them.
Foundations / Beginner
Which AI Should I Use?
A no-hype buyer's guide to picking the right AI tool for the job — without wasting money on twelve subscriptions.
The problem
It starts with the situation you're actually in.
You don't decide which AI to use — you accumulate it. This is your way out.
The tool you settled on a few months ago emails you this week: it's been "upgraded." New name, new tiers, and the plan you were paying for is gone from the list. If your confidence depends on memorizing which tool is best right now, it expires fast.
Outcomes
What you'll be able to do.
Start with the job, not the tool
You sit down to do something specific: reply to a confusing email from a landlord, turn a spreadsheet into a chart your boss will understand, write a product description, or work out why your Wi-Fi keeps dropping.
How you end up paying for the same thing five times
You learn to spot how a subscription rarely arrives as a decision. You sign up for a chatbot's $20 plan because a free limit blocked you mid-task.
The tool you forgot you're paying for
You count the AI products you pay for right now — not the ones you use, the ones quietly billing you every month.
When the demo lies
A marketing page shows a tool summarizing a 40-page contract in four seconds, flawlessly. You paste in your own messy PDF — scanned pages, footnotes, a table that matters — and the summary skips the table and invents a clause that isn't there.
Inside the book
A closer look at the work inside.
The same need, three categories
Say you want to turn a long PDF report into a short summary. Watch how the category — not the brand — decides your move. Chatbot route: paste the report into a free chatbot and ask for a one-page summary. Fast, free, and you stay in control of the output — best when it's a one-off.
Name the job in four lines
Before your next AI task, fill in four lines. It takes under a minute and saves you from opening the wrong kind of tool. 1. THE JOB (one plain sentence): _______ 2. WHAT COMES OUT? (text / image / summary / code / sourced facts): _______ 3.
Start with the job, not the tool checklist
- Plain chatbot (no browsing): Produces a clean-looking table fast — but the numbers may be from old training data or simply made up.
- Research tool (browses and cites): Slower, but each cell traces to a live page you can click and verify. This is the right home for a job that hinges on current, checkable facts.
- Agent (does the steps for you): Visits the sites, gathers the policies, and assembles the table while you do something else.
A short case study: the same morning, five different jobs
Picture an ordinary work morning with five things on your list, and watch how naming each job sends you somewhere different. "Draft a polite reply declining a vendor." That's a writing job — short, text-only, you'll edit it yourself. A general chatbot (free tier is fine) handles it in one pass.
A worked example: one task, three tools, side by side
Take job #5 from the morning list — compare three suppliers' return policies — and run it through three categories so the difference is concrete. TASK: Find three office-chair suppliers that ship to my area and compare their return windows and restocking fees. Put the result in a table with a source link for each.
