Nerd AI - Math Problem Solver

What it does

Nerd AI is a comprehensive AI-powered educational assistant designed to help students with their homework and studies. Its primary function is to solve problems, particularly in math, by allowing users to take a picture or upload an image of a question. The app then provides a detailed, step-by-step solution. Beyond just problem-solving, it offers a suite of AI tools for tasks like writing essays, translating text, summarizing documents, and generating quizzes from uploaded files.

Where it shines

Nerd AI excels in its flexibility and depth. The ability to use either a live camera or an existing photo from the library (01:07) makes the core problem-solving feature incredibly practical for various situations. The quality of the output is another strong point. For a scanned math problem, the app doesn't just give the answer; it provides a comprehensive, multi-step breakdown of the solution using the quadratic formula (01:36), effectively tutoring the user. Furthermore, its 'File Upload' feature (04:12) is a standout, transforming static documents into interactive quizzes, which is a powerful tool for active learning.

UX highlights

Multi-modal input: Users can either scan a live document or upload a photo from their library (00:58), which accommodates different user contexts.
Interactive Cropping: After selecting an image, the app provides an intuitive cropping tool (01:13) to isolate a single question, ensuring accuracy.
Step-by-step Solutions: The app presents solutions in a clear, sequential format that is easy to follow, mimicking a real tutor's explanation (01:45).
Centralized Tool Hub: A well-organized dashboard (03:14) showcases all available AI tools, encouraging discovery and repeated use beyond the initial problem.
Action-Oriented File Handling: When a user uploads a file, they are immediately prompted with high-value actions like 'Summarize' or 'Generate Quiz' (04:19), guiding them to useful outcomes.
Comprehensive History: The app saves all interactions in a history tab (07:13), allowing users to easily revisit past solutions and conversations.

Monetization & growth

The app uses a free trial model with a paywall that appears early in the user journey. After a brief feature showcase, the user is presented with the subscription screen at 00:34. The offer is a 3-day free trial that converts to a weekly subscription. The paywall includes clear feature highlights and a prominent 'Free Trial Enabled' toggle. After subscribing, the app presents a friendly confirmation screen (00:50) to reinforce the user's decision.

Who it’s for

Nerd AI is primarily for students, likely from middle school through college, who need immediate help with homework, especially in quantitative subjects like math. However, the expansive toolset for writing, research, and summarization also makes it valuable for anyone engaged in learning or knowledge work. It caters to users looking for a quick solution to a specific problem as well as those seeking a more versatile AI assistant for ongoing academic tasks.

Notes & opportunities

The app is powerful, but the user experience could be slightly refined. For instance, after getting a solution, the app shows a 'Thanks for using' modal (02:11) immediately followed by an App Store rating prompt (02:34), which can feel a bit aggressive. Spacing these requests out could feel more natural. Additionally, the camera's inability to detect content in a slightly challenging lighting situation (06:29) suggests an opportunity to improve the robustness of the image recognition model or provide users with better guidance on taking clear photos.
