Kiln AI
An AI development workbench combining evaluations, prompt optimization, synthetic datasets, retrieval, agents and fine-tuning with a desktop app and Python library.
About Kiln AI
Teams need to iterate on AI tasks and datasets while connecting evaluation results to prompt, model and agent changes.
Who it’s for
- AI engineers evaluating and optimizing applications
- Domain experts reviewing outputs and contributing datasets
When to consider it
Consider Kiln AI when you want a desktop workspace for AI experiments and a Python library for deploying the same tasks.
Tradeoffs & limitations
- The core Python library and REST server are MIT licensed; the desktop app is source-available under the custom Kiln AI Desktop EULA, which restricts redistribution without "prior written consent".
- Individual use is free, but its Kiln Pro access uses standard models with rate limits; Kiln Pro features run on Kiln servers.
