Poster2Cal

Inspiration

I often see posters on campus and on instagram and I always thought how good it would be if I can just take a photo and put the event on my calendar.

What it does

This app allows the user to drag and drag poster photos and it will create .ics files to add the events to the calendar.

How we built it

I built the frontend using React and backend using Flask. The OCR is powered by Google Cloud Vision API and text parsing is done using OpenAI's ChatGPT API with some prompt engineering.

Challenges we ran into

CORS issue

Accomplishments that we're proud of

It works pretty well and saves a lot of time and effort!

What we learned
