Just KNIME It! is a series of fun weekly challenges you can use to learn and practice your data science skills. There are challenges for all types of users and each one is rooted in real-world problems from different areas, such as finance, marketing, or healthcare.

You solve them using the intuitive, low-code tool, KNIME Analytics Platform. It’s open source, so free to download.

KNIME Community Hub is the place to go to search for workflows, engage with and share your own solutions with the community.

With your KNIME Forum account you automatically get a private and a public space on KNIME Community Hub.

  • Use your public space to share and collaborate on your work with others.

Upload your Just KNIME It! solutions to your public space on KNIME Community Hub and tag them with the Just KNIME It! tag so that they can be discovered by the community.

When does the next Just KNIME It! start?

Season 3 just started on May 15! You can join in any time. Read more about the current challlenges in this season on Just KNIME It!

Can I get a reminder when a new challenge is published?

Yes! You can register to get a reminder when a new challenge is out, and remember to upload your solution with the challenge’s tag to your public KNIME Community Hub space. KNinjas do not need to tackle a challenge as soon as it comes out, but they should finish all of them before the season is over.

Regardless of whether you can solve all challenges, we encourage everybody to try and join the discussion in challenge threads in the KNIME Forum. The exchange of tips, knowledge, and help in this space has kept us very motivated to keep publishing data problems week in and week out. And if you're feeling competitive, watch the live leaderboard!

What’s the Just KNIME It! Leaderboard?

Our leaderboard in the KNIME Forum keeps track of which users are solving the most challenges. When you upload your solution to your public KNIME Hub space, tagged with the name of the relevant challenge, we’re able to find all those tagged workflows and use that information to come up with the top users for the leaderboard.

Although the main goal of Just KNIME It! is to further educate our community, we keep the leaderboard every season to make things a bit more fun and slightly competitive.

At the end of each season we find and award our Just KNIME It! KNinjas: The impressive users who tackled all challenges in a season. The prizes include gadgets, interviews, and an entry in our Hall of Fame!
Learn more about the KNinjas and their work in our special articles on them (season 1 and season 2).
