Starting this project, I wasn’t focused on creating a groundbreaking application for end-users. Instead, the aim was to explore several tools, see how they function in a real-world setting, and evaluate their strengths and reliability. This curiosity led me to build an AI-powered stock analysis web application, leveraging a combination of powerful libraries and frameworks. Here’s how each component played a role in shaping this journey.
Project Overview
The application serves as a stock analysis assistant that helps users gather essential information about specific stocks. Users can search for a stock symbol and receive details like its market capitalization, daily maximum and minimum values over time, and recent news. The app also includes technical analysis powered by AI, offering insights that might help in understanding a stock’s potential movement.
However, this was never just about creating a stock tool. It was about testing the reliability and flexibility of certain technologies to see how well they could integrate with real-time data, support interactivity, and streamline the overall user experience.

Exploring Key Technologies
Let’s break down the three primary tools and why each played an essential role in this project.
- Assessing AI Reliability in Technical Analysis
One of the main objectives was to evaluate the accuracy and reliability of AI-generated insights in a field as dynamic as stock trading. Technical analysis has traditionally relied on historical patterns, price movements, and market indicators. With recent advancements in AI, we now have tools that can process vast amounts of data to provide recommendations.
In this application, I connected to AI APIs to perform technical analysis, allowing the AI to generate insights based on market data and historical trends. Through this, I could evaluate the credibility of AI-driven projections—whether they aligned with traditional analysis principles, how they performed in volatile markets, and how adaptable they were to changing data.
This experiment was not just about AI’s ability to make predictions but also about understanding how well it complements human judgment. I’ve found it fascinating to see where AI insights excel and where traditional methods may still be stronger.

- Streamlit: Simplifying the Development Journey
Creating an interactive, user-friendly frontend without diving deep into JavaScript or CSS can be challenging—especially for data-driven applications. Streamlit, a Python-based framework, turned out to be a perfect solution.
Streamlit is purpose-built for data applications, allowing me to create a fully functional web interface directly in Python. This framework enabled me to focus on functionality and user experience, using Python syntax alone to set up interactive features. Users can choose stock symbols, retrieve data with a click, and visualize information instantly. Streamlit handles the underlying JavaScript elements, which would have been a major time investment in a traditional development setup.
Streamlit’s widgets also made it easy to create an app where users control parameters like stock symbols and time frames, making the app more engaging. Building with Streamlit has been an eye-opener, showing how data applications can be both interactive and quick to develop.
- Plotly for Data Visualization
For any stock analysis tool, visuals are crucial. Users need clear, intuitive charts to make sense of data trends, spot anomalies, and gain a deeper understanding of a stock’s history. Here, Plotly brought a wealth of visualization capabilities to the project.
With Plotly, I could generate a wide variety of charts with minimal code, from candlestick charts for price movements to line graphs showing stock trends over time. What’s even more remarkable is how easy it is to create interactive elements in these charts, allowing users to zoom, pan, and hover for specific data points. Plotly’s versatility in rendering clean, professional visuals has greatly enhanced the app’s usability and appeal.
In addition to technical ease, Plotly’s customizability means I can keep adding layers of information—overlaying moving averages, for instance, or annotating significant events.

Lessons Learned and Reflections This project has underscored the importance of choosing the right tools for the job. Each technology served its unique purpose:
AI APIs provided a chance to evaluate machine learning in a technical analysis context, revealing both the possibilities and limitations of AI-driven predictions. Streamlit made building an interactive app with machine learning data accessible and rapid, helping me focus more on functionality than on frontend specifics. Plotly delivered beautiful, responsive charts that brought clarity to complex data sets, an invaluable feature in a stock analysis setting.
Going forward, I’m excited to continue experimenting with this app—adding more features, testing additional data sources, and exploring other libraries that could enhance the experience. For now, this has been a rewarding journey that’s deepened my appreciation for each tool’s capabilities, while giving me a hands-on way to expand my skills in AI and data-driven web applications.
