AI summary
Auto-generated overview of what this skill does and when to reach for it.
A free, local-first workbench to build, evaluate, and optimize AI systems with evals, RAG, agents, fine-tuning, and synthetic data—all in one tool.
Use this when
- You need to evaluate AI outputs against custom criteria
- You want to auto-optimize prompts or agent workflows
- You’re building RAG systems with drag-and-drop document uploads
- You need to generate synthetic data for fine-tuning or evals
- You’re fine-tuning models across 60+ providers without vendor lock-in
Don't use when
- You need a cloud-only SaaS with managed infrastructure
- You’re building a simple chatbot with no evals or optimization needs
- You require real-time multi-user collaboration beyond Git sync
Capabilities
- Auto-generate evals from your own data in ~10 minutes
- Drag-and-drop RAG with auto-generated evals from your documents
- Auto-Optimize searches prompt/model/tool combinations to maximize eval scores
- Zero-code fine-tuning across 60+ models (Qwen, Llama, GPT, etc.)
- Synthetic data generation for evals or fine-tuning in minutes
- Git-native sync for team collaboration without extra tooling
