I really like how Call the Card handles the data locally. It is fast and doesn't send anything out, which is cool. But I am curious about the cost. The site shows the data and the model trees, but it does not clearly state if there is a subscription fee or if it is free. It seems like a good tool, but I would like to know the pricing structure before I get too invested in using it regularly. It feels a bit vague on the business side.
The availability of the model data is good, and the client-side execution is smooth. However, the scope seems limited to specific fight metrics. It would be helpful to see more context around the features. For now, it serves its purpose well enough for basic analysis, though.
What an absolute joy to explore the vast dataset available through Call the Card! The sheer volume of historical fight information, spanning from 1994 all the way through to 2026, is truly impressive. I am amazed by the depth of the win model features, which include everything from height and reach differences to nuanced metrics like significant strikes landed per minute and control percentage. It feels like having a complete library of mixed martial arts history right at my fingertips. The fact that this runs entirely client-side means there is no lag, no waiting for servers, and no privacy concerns because nothing I type is sent anywhere. This level of transparency and performance is exactly what I look for in a sports analytics tool. I can dive deep into specific matchups, comparing opponents across decades with ease. The enthusiasm in the data structure is palpable. Every feature, from takedown averages to stance differences, is there for the exploring. It is a fantastic resource for anyone serious about understanding the evolution of UFC fights. I love how accessible and comprehensive it is.
Call the Card operates entirely client-side, ensuring privacy since nothing you type is sent elsewhere. This transparency is refreshing, though one might wish for clearer documentation on how the trained model processes the extensive fight data listed.

About Call the Card
Call the Card is a client-side web tool focused on UFC fight predictions. The site presents a weekly card of upcoming fights along with last week's results and a fantasy matchup section. It is built around a machine learning win model trained on UFC fights from 1994 to 2026, using fighter statistics such as Elo rating, height, reach, age, fight experience, win percentage, finish rate, streaks, layoff length, striking metrics, grappling metrics, control percentage, and stance. The entire application runs in the browser, with the page explicitly stating that no user input is sent to any server. The bulk of the visible content consists of the underlying model data, including feature lists and decision tree values used to generate win probabilities.
