Cursor’s Composer can generate a complete HTML/JavaScript study app from a detailed prompt that specifies streaming, tutor behavior, and UI elements like a Pomodoro timer.
Briefing
A browser-based “study chatbot” can be built quickly by combining Cursor’s AI coding assistance with an OpenAI API call—then iterating on features like conversation memory, a Pomodoro timer with a break alarm, and a one-click reset. The practical takeaway is that a personalized learning app isn’t just an idea; it can be generated from a single prompt, wired to an API key, and refined through successive AI-assisted code changes.
The build starts with a simple goal: an HTML app that lets a user choose a topic (the example uses Python) and receive a structured learning loop. The interface includes a text input for questions, an AI response that returns Python code snippets in Markdown code blocks, and follow-up behavior that explains the snippet and asks related questions so the learner can iterate. A Pomodoro-style timer sits in the bottom-right corner, supporting start/stop and timed sessions.
Cursor is used like a VS Code-style environment. A new project folder (“study”) is created, then AI “rules” are configured to act as system instructions. Composer—invoked via a keyboard shortcut—generates the initial index.html from a detailed prompt. That prompt specifies streaming responses, styling requirements (contrast and readability), a “python code tutor” system message, and UI elements including the Pomodoro timer. The generated JavaScript includes an API key placeholder, which is then filled from the OpenAI dashboard (API keys section). After saving, the app is served locally and runs in the browser.
Early testing reveals a key limitation: the chatbot doesn’t remember prior messages, so follow-up questions lose context. The fix is implemented by storing conversation history and feeding it back into subsequent API calls. After this change, the assistant produces coherent, context-aware answers—for example, returning the expected output for a Python for-loop example and continuing with explanations and additional questions.
Next comes timed study flow. A 5-minute break timer is added to trigger after the main work block ends (the example tests by temporarily shortening the work interval to one minute). The break logic uses a state flag (an “is break” boolean) and an alarm function; a small beep confirms the transition, though it’s described as underwhelming. Finally, a “clear conversation” button is added to reset conversation history, clear displayed output, and wipe the input field, enabling a fresh start without stale context.
The app is then customized beyond Python. The system instructions are swapped to a World War II tutor persona, with a quiz after each lesson and student answers provided through chat. A refreshed run produces a lesson question (e.g., the official start of World War I) and supports interactive quiz responses. The overall result is a flexible template for personalized study: change the system prompt, keep conversation memory, and iterate on UI features like timers and reset controls—without hand-coding every component from scratch.
Cornell Notes
A personalized study chatbot can be generated and iteratively improved using Cursor’s Composer and an OpenAI API call inside a single-page HTML app. The initial prompt produces a streaming, tutor-style interface that returns code snippets in Markdown and includes a Pomodoro timer. The first major upgrade is adding conversation memory by storing prior messages and sending them back as context, which makes follow-up questions coherent. Then the app gains a 5-minute break timer with an alarm and a “clear conversation” button that resets history, output, and input. Finally, the tutor role is swapped from Python to World War II quizzes by changing the system instructions and lesson/quiz flow.

Review Questions
- What specific change made the chatbot’s follow-up answers coherent, and how does that relate to conversation context?
- Describe the state logic behind the Pomodoro work-to-break transition and how the alarm is triggered.
- How would you modify the system instructions to switch the tutor from code explanations to quiz-only mode for a chosen topic?
Key Points
- 1
Cursor’s Composer can generate a complete HTML/JavaScript study app from a detailed prompt that specifies streaming, tutor behavior, and UI elements like a Pomodoro timer.
- 2
An OpenAI API key must be inserted into the generated code (or provided via environment variables) for the app to call the model.
- 3
Adding conversation memory requires storing prior messages and including them as context in subsequent API requests.
- 4
A 5-minute break timer can be implemented by tracking whether the app is in work or break mode and triggering an alarm when the break starts.
- 5
A “clear conversation” button should reset conversation history and also clear visible output and the input field to avoid stale context.
- 6
The same app can be repurposed for new subjects by swapping the system instructions (e.g., from Python code tutoring to World War II lesson-and-quiz flow).
