What is Humanloop?
Humanloop is a collaboration platform for teams building products on top of large language models. It centralizes prompt management, model fine-tuning, and performance evaluation into a single workspace, enabling both engineers and domain experts to contribute to LLM product quality.
What Sets It Apart
Humanloop places a strong emphasis on human feedback loops. Teams can collect feedback from end users or internal reviewers directly in the platform, then use that feedback to fine-tune models or improve prompts — creating a continuous improvement cycle for AI products.
- Prompt management with version history and environment promotion
- Fine-tuning workflows for OpenAI and other models
- Evaluation with human and automated feedback
- Integration via SDK for Python, TypeScript, and REST
