Introducing pi-chat.ml, looking for contributors.

Hello, I started this project as part of a Hackathon (BuilderHacks S2) and would like sharing it with you.

The project

The basic idea is developing chatrooms that allow friends to study together by submitting questions with a ML model in the backend verifying the answers. The latter is important because oftenly, answers are checked like this:

NLP and other technologies like CAS are used to smartly grade submissions like so:

Grading questions

Hence, several techniques are used to verify answers:

Text strict: As you might expect, verifies that expected answer and submission match exactly.
Text medium: Transforms to lowercase and strips away punctuation (and parentheses, apostrophes, etc) to verify that expected answer and submission match loosely.
Text similarity: Uses NLP (Though spacy) to verify that the similarity score for answer and submission is above 0.8
Scalar: Uses quantulum3 to identify scalars with unit and number and verify the answer matches submission (e.g., 10 cm = 10.0 centimeters)
Math: Uses CAS to make sure mathematical expressions match. (e.g., "(x*x)/2" == "0.5*x^2")

Other features

Additionally other features include KaTeX support, a drawing canvas and chatroom generation.

In the future

I developed the project in under two days as part of the hackathon but I intend to take it even further in the future, solving many bugs (and there are many) as well as integrating new features. I am open to feedback as well as working together with other people to make it happen.

Technologies used

Frontend: React
Frontend (real time communication): hop.io
Backend: Python

Please let me know if you have any feedback and if you'd be interested in participating.

Introducing animated-web-components

TL;DR

Hello! I have recently began developing a library that uses web-components to wrap content and provide several basic animations. I am very excited and have big plans for the future, as I believe a lot of people can benefit from this.

This is my first time doing a project of this kind, and I would like to grow a community around it, where other people can share their ideas and help me grow the project.

If you're interested, please check it out here

Any type of feedback, comments and everything is greatly appreciated :D

A little backstory

Before the pandemic, I would often make my girlfriend (yup, I defied the programmer nature lol) hand-made popup greeting cards. I have always enjoyed the process of creating (be it programming, design and even origami), so I have a great time doing them. My girlfriend really likes them as well.

However, when the pandemic started, it became increasingly more difficult for us to see each other often. While I could make a physical card and ship it to her house, I wanted to challenge myself into doing something different (I also find constantly receiving packages can become annoying, even if in good faith).

I decided to web versions of such cards, making them as dynamic and animated as possible. I have done a few, and each time I have had to "reinvent the wheel" by reimplementing, debugging and improving simple functionality (e.g., a simple typing animation can be more challenging than it seems. Think Regex challenging).

I read about web-components and how they make it super easy to implement new functionlity. I thought there should be a way to implement such animations with such ease,
So I created one.
