Custom models trained on your data

Feyn is an end-to-end service for building custom models from your data. Our models learn how your product actually works, handle the rare cases that are costly to get wrong, and grow sharper the longer they run. Our engineers start by reviewing your current setup and agreeing on what quality means for your workflow. Then we train a model on your data. Once it ships, new cases feed back into training so the model keeps improving. The result is a model that runs faster, improves with use, and is yours to own.

✨ Why Chonkie?

Most AI products today don’t fail because of the model. They fail because they’re fed disorganized, bloated, or incomplete data. The results in wrong answers, slow performance, and expensive bills. There are some existing tools that try to address this, however they are either:

  • 🔻 Too slow or bloated
  • 🧱 Too barebones — feels like reinventing the wheel every time

So we built Chonkie — fast, lightweight, and comprehensive.
