Why Recap?

TL;DR

Recap is the best way to ensure you understand a concept. Most online resources and practice don't cover exactly what you learn at school. How do you know if you have fully understood a concept or not? You for sure don't want to "wait and find out 😣".

More information:

• Impact: We are the first quizzing iOS app to use Gemini's large context window to deliver accurate quizzes. Our solution is designed to be easy and enjoyable for everyone, including people with disabilities. SwiftUI provides robust accessibility features out-of-the-box, such as VoiceOver, Dynamic Type, and support for various input methods. By choosing SwiftUI, we ensure that our app is accessible to a wider audience, including those with visual, auditory, and motor impairments. Additionally, we have localized the app to Spanish, making it accessible to a broader user base. Our app has the potential to contribute meaningfully to improving people's lives by providing personalized learning experiences.

• Remarkability: Our approach is surprising both to those well-versed and not well-versed in Large Language Models (LLM). The use of Gemini 1.5 Pro for personalized quizzing is unprecedented. This innovative use of LLM technology sets our app apart from existing solutions and showcases the potential of advanced AI in educational tools.

• Creativity: Recap differs from existing applications in both functionality and user experience. We use creative problem-solving approaches to offer a unique and personalized quizzing experience. Our app supports input from various resources like images, URLs, and plaintext, which is not commonly found in other quizzing apps. This flexibility allows users to create quizzes tailored to their specific learning materials.

• Usefulness: We have a well-defined target user persona—students who need personalized quizzes to reinforce their learning. Our solution addresses specific user needs by allowing input from various resources like images, URLs, and plaintext. The app's design ensures that it meets these needs effectively, helping users to better understand and retain the concepts they are studying.

• Execution: The solution is well-designed and adheres to software engineering practices. The LLM component is also well-designed and follows Machine Learning (ML)/LLM best practices. By leveraging SwiftUI, we ensure that our app is not only visually appealing but also highly accessible and inclusive. The app's architecture and code quality are robust, modular, and maintainable, ensuring that it can be easily extended and updated in the future. We follow best practices such as code reviews and continuous integration to maintain high standards of code quality and reliability.

How to generate a quiz using Recap

1. Install Recap from the App Store.

• You can also follow these installation instructions to install it from GitHub

2. Complete the Onboarding process and input your free Gemini API key

• If you aren't able to get the key from your iPhone, try opening the link on your laptop.
• When you attempt to generate a quiz, you'll see a popup saying "Input your API key!" To fix this, open Settings (top right corner), scroll down, and click on Gemini under the model configurations. You'll see a textfield with a place to input your API key.

Caution

Be sure not to share your API key with anybody else!

3. Add attachments using the buttons marked for images and URLs, and add text-based attachments to the textfield.
4. Click the plane icon to start generating the quiz! Enjoy!

Prompting Instructions:

• No need to use phrases such as "quiz me on [...]." We've already instructed Gemini to generate you a quiz. Just simply add attachments relating to whatever you'd like to be quizzed on.
• Free users have a 32K input limit on the Gemini 1.5 Pro model, so this means you should not exceed the limit by adding too much content. Switch to 1.5 Flash to have a significantly larger input limit.

Tip

Try to only generate quizzes on a singular topic (eg. Cats) rather than multiple topics (eg. Cats, Math, Java etc.)

Tip

If you'd like to choose how many of each you want or add further customizations, add those instructions to the prompt (the textfield). Ex: In the quiz, put two multiple choice questions about [...], one multi-select, and three free response questions.

How It Works

As mentioned previously, we prompt Gemini with your input, and it returns a JSON with the quiz info, which we parse and put in a JSON. We then parse the JSON, rendering the quiz UI.

FAQ

• Why do I need to input an API key?
  • Unfortunately, as an indie developer, I can't afford to provide free AI access for everyone. However, Google, a very generous company, offers powerful AI tools for developers at no cost. All you need to do is input the key. If you need help adding the key, feel free to contact me or submit an issue!
