Project Overview

Learn & grow with QuestnQuiz, your online quiz maker. A user can create quizzes with open AI. The app consists of simple question generation, MCQs, true/false quizzes, as well as a defined quest. It is a one-stop for educational experts and HRs to come up with great questions to test an interviewee or a class test. The quiz maker has a unique feature of 'scan and make,' which allows one to scan a topic and make questions for a quiz using an open AI tech stack for easy and hassle-free quizzes

Challenges

Ensuring AI Accuracy in Responses

• A significant challenge was ensuring the AI accuracy in response when generating quizzes and quests.

• Inaccurate AI outputs could lead to incorrect questions and unreliable quiz content.

• Optimizing the model to produce consistently accurate results required extensive testing and fine-tuning.

Optimizing AI Turnaround Time

• The turnaround time of the AI for generating quizzes needed to be significantly reduced.

• Slow response times would negatively impact the user experience and app usability.

• Balancing speed with accuracy required careful optimization of the AI pipeline.

Handling Duplicate Keyword Searches

• When different users searched with the same keyword, they would receive redundant API calls.

• Repeated API calls for identical prompts wasted resources and increased server load.

• There was no caching mechanism to store and retrieve previously generated responses.

Maintaining Consistent Responses Across Users

• Ensuring that the same keyword consistently produced the same response was critical for reliability.

• Without a unified response store, results could vary between users for identical queries.

• A consistent experience was essential for educational and HR use cases where standardization matters.

Our Solution

Guided AI with Custom Instructions

• We have created a specific set of instructions and input texts that are used to guide the model to reach the end goals.

• Custom prompts were designed to ensure accurate and relevant quiz and quest generation.

• The instruction set was refined iteratively to improve output quality and consistency.

Caching Repetitive Keywords and Replies

• We use a variety of algorithms to store the repetitive keywords and replies.

• When a new user enters the same prompt, we can quickly retrieve the stored response.

• This saved a lot of time and eliminated an API call to regenerate the quiz or quest.

Optimized API Call Management

• The system detects duplicate prompts before making an outbound API call.

• A local response store is checked first, reducing unnecessary calls to Open AI.

• This approach significantly lowered operational costs and improved response speed.

Scalable Response Storage Architecture

• Responses are stored in a structured database indexed by keyword and quiz parameters.

• The storage system scales efficiently as more users and prompts are added over time.

• Retrieval is optimized for sub-second response times to maintain a seamless user experience.

Features Implemented

QuestnQuiz delivers a complete AI-powered quiz creation experience. Each feature is designed to make quiz and quest generation simple, fast, and shareable.

1. Create Profile

It has a very simple process for user signup. One has to fill in personal details like name, email, and password to create a profile in the quiz app.

2. The Trendsetters

Do you want to know which quiz is trending on the app? The dashboard shows six quizzes and quests that are taken by users the most. Also, these are the ones that are highly searched by the users in the online quiz app.

3. Generate Quiz

A user can create a quiz just by adding keywords. It does allow a user to set the number of questions, adjust the difficulty levels, and assign a specific question format. One can also go for MCQs or true/false quests.

4. Generate Quest

The quiz app development also renders great quests as per one's needs. You can easily decide on the number of questions, the level of the test, and the format of the quests. It has the same user interface and navigation facility as the quiz generation feature.

5. Scan By Text

To make it more fun, the online quiz maker app consists of the ability to extract keywords right from the text & make a quiz out of it. One can do so by a scan-by-text function with the in-built camera. It will identify similar words to generate an online quiz for you at ease.

6. Quiz Share

One can create and share the quiz with others. The quiz developing app allows users to share the quiz with their contacts and challenge them to solve the same. It also shows scores for the quizzes taken as per specific topics.

7. The Records

QuestnQuiz retains a history of records of the last ten quizzes and quests. The quiz history displays all questions with the correct answers. At the same time, the quest history archives 10 questions and their right answers.
