AI for One Job: Student, Small Business, Job Seeker, Teacher, Writer

Pick the lesson that matches your job. Two real tasks, prompts you can run right here, and a straight answer on which free or $20 tool does it well.

For people who have one job to get done and no interest in becoming an AI expert to do it. You have used a chatbot once or twice, you are not sure whether to pay for one, and you want the two or three prompts that matter for your situation.

Frequently asked

Do I need to take all five lessons?

No. Each lesson stands alone for one job. Take yours; if you have two jobs (a teacher who also writes, say), take both. The skills repeat on purpose, so the second lesson will go faster.

Which AI tool does this course use?

Any of them. Every prompt works on the free tiers of ChatGPT, Claude and Gemini, and the Try it boxes run on cheap models through this site. Each lesson names the cheapest tool that does that job well today and links to the matching best-of page.

Will I need to pay for anything?

Not to complete the course. Every task runs on a free tier. Each lesson ends by saying when a $20 plan genuinely adds value for that job, and for most of these five it is only at high volume or when you need file uploads.

Why are the same skills repeated across lessons?

Because the two skills (draft from your own material with a named format, then check one fact) are the whole game for beginners, and they stick when you see them in your own job rather than in the abstract.
