When an explanation isn’t enough,
ask Smith.
Smith
Example chatI chose “shift in demand”. Why is my answer wrong?
The question says only the good’s own price changed. With other factors unchanged, that means a movement along the demand curve, not a shift.
A shift happens when something else changes, such as income or preferences.
Price changes: move along.
Other factors change: the curve may shift.
Named in honour of Adam Smith, the father of modern economics.

After a test
See the whole test clearly.
Open the Results page, select Insights and choose Analyse this test. Smith can look across the full result—not just one question—to show what went well, bring related gaps together and give you a practical revision order. When reliable Focus mode timing is available, it can also point out where time may need attention.

During your preparation
Know where to focus next.
Open the Preparation page, select Progress and choose Review my preparation. Smith connects your past tests, how much each subject matters in the exam, the time you have left and your current plan. It helps you see your strengths, your most important gaps and the work that deserves attention now.

A step further in personalisation
Things Smith remembers.
Chosen by you.
Prefer everyday examples or explanations one step at a time? Tell Smith, then choose to remember that message. It can help make future replies about the same exam and topic more useful to you.
- Turn it on. After your first reply, open Chat options (•••), then Things Smith remembers. Turn on Let Smith remember.
- Choose what to remember. Choose a short message you wrote and select Remember this.
- Stay in control. View remembered messages in Settings & usage. Select Forget this to remove one, or turn the feature off to forget them all.
For example: “Please use a simple example when explaining income and substitution effects.” Choose Remember this so Smith can use your preference for later help on that topic.
This is off by default. Nothing is remembered automatically. Forgetting a message does not delete your saved chat. Your test results and study plan stay unchanged. See privacy details.
Usage & credits
Complimentary credits
for AI assistance.
Included once · Where enabled
10,000 credits
Complimentary with any exam package.
Active exam package access is required. Credits do not represent a fixed number of questions or replies.
View your usageNew replies use credits.
Each new reply uses credits, whether you type a question or choose a suggested prompt. Longer questions, conversations and replies can use more credits.
Saved help stays accessible.
Saved chats, test explanations, reports, exports and privacy controls do not use AI credits. Failed or safety-withheld replies do not use your credits.
How credits work
Tokens are small pieces of text, such as a word or part of a word. Smith uses tokens to read and reply. Your credits are used based on token usage—not just the message you type.
The test question, its explanation, earlier messages needed for context and Smith’s reply all count. Longer conversations, detailed replies and questions that need more working out can use more tokens and credits.
Check your remaining credits in Settings & usage.
Credits are complimentary once per exam package. Deleting chats does not add more. Daily limits may apply. Credits cannot be transferred, and buying credits is not supported yet.
Good to know
Useful help. Honest limits.
Smith supports your learning. It does not replace your teacher or the need to check an answer.
