PrepTrack AI

Inspiration

It’s really easy to set a big goal, but much harder to know what steps to take each day to reach it. I often found myself writing vague goals like “do well on an exam” or “work out more” and then not knowing how to break them down. I wanted to make a tool that could suggest tasks for me and give a simple hint on which ones might be harder or easier, so I could plan my time better.

What it does

• Lets you type in a goal in plain language.
• Suggests a list of tasks related to that goal.
• Saves those tasks in Firestore so they don’t disappear.
• Runs them through a small model that gives each task a “difficulty hint.”
• Shows a badge for each task: Likely, 50-50, Tough.

Right now, it’s just about suggesting and scoring tasks, but it is set up to turn goals into daily study, workout, or project plans.

Challenges I ran into

• Making sure the model’s input format always matched the training data.
• Getting the task generator to return clean JSON instead of messy text.
• Figuring out how much to build for a first version and not trying to do everything at once.

Accomplishments that I am proud of

• Built a working full-stack project on my own.
• Connected a web app, database, and Python service together for the first time.
• Got task suggestions and task predictions to work in one flow.
• Made something flexible enough to use for school, fitness, reading, or personal projects.

What I learned

• How to connect Next.js with Firebase for storing data.
• How to serve a machine learning model using FastAPI.
• How to export data from Firestore and reuse it in training.
• The importance of starting small with an MVP before trying to add advanced feature

What's next for PrepTrack AI

• Add Google login/logout so tasks are tied to accounts.
• Break goals into daily or weekly schedules instead of just showing a task list.
• Reschedule tasks automatically if you fall behind.
• Sync tasks with Google Calendar.
• Improve predictions by learning from each user’s history.
• Add progress tracking and a simple dashboard for stats.
• Make the UI cleaner and more mobile-friendly.
