Cardinal is my go to app to use for debate. I cannot stress enough how much this tool has helped me. During a debate the opponent had a piece of evidence that I just could not refute. So In-between rounds I used Cardinals attack a card tool to counter the piece of evidence, it worked great. Next round our opps were using the same evidence but this time we were able to counter it.

Cardinal is a great app to use, it genuinely saves me hours of finding cards and helps me prep way faster than before. Everything else like the card cutting tool works great as well. I'm looking forward to a great season using cardinal!

I just had a huge tournament, and between rounds, I needed to prep frontlines, and I used Cardinal which helped me find the perfect card, and I won that round, which led to me getting 2nd speaker.

In my 4 years of doing debate, I have never seen a tool as good as this, not to mention most tools are completely free! This does everything I would want a card-cutter tool to do and more. I highly recommend this to anyone doing debate, no matter their age or experience level. Thank you Cardinal!

As someone who has placed at multiple debate tournaments and earned top speaker awards, I can honestly say that Cardinal has been one of the biggest upgrades to my prep. It makes finding strong sources, cutting clean cards, and organizing evidence insanely fast, which gives me way more time to focus on strategy and actually winning rounds. The platform feels like it was made by people who genuinely understand what competitive debaters need. Cardinal has helped me prep more efficiently, build stronger cases, and find responses that I probably would have missed on my own. Whether I am preparing weeks before a tournament or doing emergency prep right before a round, it consistently comes through. The card-cutting tools are smooth, the sources are useful, and the entire process is way less stressful. I have used a lot of debate resources, but Cardinal is easily one of the most valuable. It is not just a convenience—it gives debaters a real competitive advantage.
