So, what is The Square?

Imagine a busy town square where scientists, students, professors and data lovers meet to share their best ideas and tools, just like sharing a cup of coffee. The Square is our online version of that kind of place. It is a friendly space where people from around the world come together to exchange code, datasets, and smart ways to work with chemical data. Everything is free and open, so you can explore, use, or even improve what others have shared.

In simple terms, The Square is the central repository of Lovelace’s Square, one of the platform’s three main pillars, alongside The Library (learning materials) and Ada (an AI assistant). It is the platform’s technical core, focused on the doing part of data analysis.

Why The Square exists

We know the struggle. For years, many powerful chemometric methods were locked away in expensive proprietary software, far out of reach for students or labs on a tight budget. New techniques often appear in scattered code repositories with little documentation, which makes them hard to learn or trust. The Square removes those barriers and brings everything into one open, easy-to-access space.

We call it “The Square” because we imagined it like a public square: a place where people gather to share, collaborate, and innovate. We are not promising to change the world overnight, but we do hope to make life a little easier (and maybe more fun) for anyone working with chemical data. So bring your curiosity, maybe a cup of coffee, and come join us in The Square 😄.

What The Square offers

All the main chemometric methods are included, from classic techniques like PCA and PLS to newer models. You can also explore real datasets to practice and test your ideas.

All tools and datasets are fully open-source or released under similar free licenses, such as the MIT license. You are free to read the code, use it, change it, and share it. Nothing is locked or hidden.

We encourage each method and dataset to include clear explanations, practical examples, and scientific references. This helps users understand how things work and makes results easier to repeat and verify. The Square is not only easy to use, but also reliable and ready to support real scientific work.

One-Stop hub

All the core chemometric methods in one place. From classics like PCA and PLS to newer techniques and real datasets for practice. No more searching across the internet.

Completely Open

Every tool and dataset is free under permissive licenses (like MIT). You can read the code, use it, change it, and share it without worries.

Zero barriers

The Square runs in your browser with no installation, no registration, and no paywalls. Just click and start exploring.

Reliable & reproducible

Each method or dataset comes with clear documentation and scientific references. Nothing is a black box.

Open Science and Community

The Square is built on two important ideas: open science and working together as a community. We believe science should be open to everyone. When tools and data are free to use, research becomes easier to repeat, improve, and share. This helps science grow faster and become more fair.

But open science only works when people take part. That is why The Square grows with help from its community. If you are a researcher with a new method or a student who found a useful dataset, your contribution is welcome and valuable.
