My AI Tips

Pick who you are. Copy a prompt, paste it into any AI app.

Students

Turn your notes into a quiz before exams

Paste your chapter notes into a free AI chat and ask it to write practice questions with answers hidden. Attempt them first, then check. Testing yourself beats rereading, and it shows gaps before the exam does.

PromptI am preparing for my [subject] exam at [college name] in [month]. Here are my notes on [topic]: [paste notes]. Make 10 questions of mixed difficulty, show answers only after I reply, and mark which ones I should revisit.
Students

Get a step-by-step walkthrough of hard problems

When you are stuck on a maths or physics problem, ask the AI to guide you one step at a time instead of giving the final answer. You keep the learning, and you can check each step against your textbook before moving on.

PromptSolve this [subject] problem with me one step at a time: [paste problem]. Wait for my answer after each step, and tell me if I make a mistake. My exam is in [number] days and my level is [class or year].
Developers

Ask AI to review your diff before pushing

Before you open a pull request, paste your code change into a free AI chat and ask for bugs, edge cases and unclear names. Catching these early saves your reviewers time and keeps your commit history clean.

PromptReview this [language] code change for bugs, security issues and edge cases: [paste diff]. The code is meant to [what it does]. List problems by severity and suggest a fix for each one.
Developers

Compare model costs on your own prompts

Keep a small set of 20 real prompts from your app and run them through a cheaper model and your current one. Compare answers side by side. Cheaper models can be enough for simple steps, and this shows where quality drops.

PromptHere are my [number] test prompts from my [app type] app: [paste prompts]. For each one, give me a short checklist to judge whether an answer is good enough, and a score from 1 to 5 I can use to compare two models.

Turn a rough idea into a one-page plan

Write your idea in five messy sentences, then ask a free AI chat to turn it into a one-page plan with the customer, problem, price and first 30 days. You get a clear draft to test with real customers this week.

PromptI am building [product] for [target customer] in [city or region]. The problem they face is [problem], and I plan to charge [price]. Write a one-page plan with a 30-day test, the three riskiest assumptions, and a short message to ask 10 customers for feedback.

Estimate your monthly AI bill before you launch

List every AI call your product makes per user, then ask a free AI chat to estimate monthly cost at three user levels. Seeing the numbers early helps you pick a cheaper model or limit free usage before bills grow.

PromptMy app [name] calls an AI model [number] times per user per day, with about [tokens] words per call, and I expect [users] users next month. Estimate my monthly cost using the price list of [provider], and show the math in a simple table.
