• “Make me a MugUp deck on the French Revolution with 30 flashcards and 15 multiple-choice questions.”
• “Here are my lecture notes. Turn them into a MugUp project with one topic per heading, and flashcards for every term I define.”
• “Add 20 Spanish verbs to my Spanish project as pairs, with the English meaning on the right.”
• “Look at my Biology project and add fill-in-the-blank questions on anything the flashcards don’t cover yet.”
• “Check the multiple-choice questions in my Networking topic and fix any where the right answer is obviously the longest.”

When it’s done it gives you a link to the topic. Open it in MugUp and press Play. The questions are scheduled for review like any others, and count towards your streak.

• It can add up to 100 items at a time, and 2,000 a day.
• If it adds a card or question that’s already in the topic, MugUp skips the repeat.
• The writing is done by your AI app on your account with it, so it uses none of your MugUp generations. Your AI app may have limits of its own.

In MugUp, open Settings, then AI apps. Every app you’ve allowed is listed there with a Disconnect button. After you press it, the app can’t sign in again, and anything it was already doing stops within an hour. Nothing it made is removed: the decks are yours.

The app says it couldn’t connect

Check you pasted the whole link, https://mugup.app/api/mcp, with nothing before or after it. Some apps only let you add your own connector on their paid plans.

The MugUp page shows See Pro plans instead of Allow

Your MugUp account is on the free plan. Connecting an AI app is part of Pro.

The MugUp page says the request has expired

The sign-in has to be finished within a few minutes. Go back to the app and start connecting again.

The AI answers without using MugUp

Check that MugUp is switched on for this chat, then mention it by name: “Use MugUp to make me a deck on…”.

It asks me to sign in to MugUp again

That happens from time to time, and after you disconnect it in Settings. Sign in and press Allow again.

It says I’ve reached the daily limit

An AI app can add up to 2,000 items a day to your account. Nothing from the refused request was added. Try again tomorrow.

It got a question wrong, or I want something removed

Ask it to fix the question, or edit it yourself in MugUp. To remove a card, topic or project, delete it in MugUp: AI apps can’t delete anything.
