"Other ML tools are painfully slow. But with Nyckel, the model auto-retrains after every change. It's shocking and awesome."

Spinning up a new classifier shouldn't be tedious

AI/ML tools like Azure or Vertex AI take forever to fine-tune and have "always-on" pricing - making it tedious and expensive to launch new models. Fortunately, with Nyckel's elastic pricing and real-time retraining, you can cost-effectively build classifiers at scale.

Built for devs wanting a no-frills way to train classifiers.

The only AI tool focused on machine learning classification.
