Welcome to Nyckel

Nyckel is built for teams who need reliable classification — on images, text, or structured data — without deep machine learning expertise. Choose the path that fits how you work.

General audience

Learn Nyckel through the console. No code required to get your first function running.

Use a pretrained classifier, upload examples to train a custom function, and review predictions — all from the UI.

Developer Platform

Build with the Nyckel API. Learn how functions work, how to integrate them into your application, and how to close the feedback loop so your function improves over time.
