Kiln AI
The AI Workbench for Teams: build, evaluate, and optimize AI systems.

Kiln AI is a workbench platform that helps teams build, evaluate, and optimize AI systems through tools like evals, fine-tuning, RAG, agents, synthetic data generation, and prompt optimization. It offers a user-friendly desktop app alongside an open-source Python library for production deployment. The platform supports all major models and can run locally or in the cloud.
Users work through a desktop app or open-source Python library to define tasks, run evaluations, fine-tune models, and optimize prompts across any supported model provider.
