## What is the difference between Free, Pro and Max?

Free lets you explore Memo's core workflow. Pro suits regular study and AI use. Max suits heavier AI use. See [Memo Plans Comparison](https://www.memo.cards/help/getting-started/memo-plans-comparison) and your purchase options in **Settings → Subscription**.

## How does usage work?

Memo uses shared energy for supported AI actions. Open **Settings → Usage** for your remaining balance and monthly reset. A plan does not promise a fixed number of generations. See [Understanding Energy in Memo](https://www.memo.cards/help/getting-started/understanding-energy-in-memo).

## Can I try Memo before choosing a paid plan?

You can explore Memo on Free. Eligible offers have their own requirements and claim flow. For the HKU student offer, use **Settings → Claim** and follow [Pro Account for HKU Students](https://www.memo.cards/help/billing/pro-account-for-hku-students).

## Can I cancel or change my subscription?

Open **Settings → Subscription** for the actions available to your account and review any confirmation screen. An Apple-billed subscription is managed through Apple. See [Cancel Subscription](https://www.memo.cards/help/billing/cancel-subscription).

## Where do I ask about a refund or unexpected charge?

Use the request route in [Refund Policy](https://www.memo.cards/help/billing/refund-policy). Include the account email, date, amount and receipt reference. Cancellation and refund review are separate.

## Is there an iPhone or iPad app?

Yes. Memo has a native App Store app for iPhone and iPad. Android users can use the browser-installed web app. See [Memo Desktop and Mobile Downloads](https://www.memo.cards/help/getting-started/memo-desktop-and-mobile-downloads).

## Can I export flashcards?

Memo supports Anki and RemNote export from supported flashcard sets. Select the export format from the set's download options. PDF reference-image quality is controlled in **Settings → Flashcard Display**; re-export to apply a changed setting.

## How do I create study materials?

Add sources to a notebook, then use Memo Agent and supported Studio tools to create study materials. Review generated content against your sources.

## Where is the HKU MBBS QBank?

On the web, open **Settings → Optional Features**, enable QBank and open it from the sidebar. Complete the access steps shown inside. See [Find and access the HKU MBBS QBank](https://www.memo.cards/help/getting-started/find-and-access-the-hku-mbbs-qbank).
