What is Nyckel?
Custom classifiers built from your data in minutes.
Who is Nyckel best for?
Nyckel is best for product teams without ML engineers who need spam, defect or fraud checks made through an API.
Developers adding classification to an app
Each decision is one API endpoint that returns a label and a confidence score, and Nyckel picks and hosts the model behind it.
Content moderation and spam filtering
Text and image classifiers flag spam, scams or unwanted content in volume, with a review queue for the unsure cases on Business.
Quality checks from photos
Image classifiers and object detectors spot defects or count items in product photos, trained on examples from your own line.
Teams without machine learning staff
It tests hundreds of models against your data and surfaces the examples worth labelling, so accuracy improves without an ML engineer.
