- **Spans & Annotations**: Retrieve spans and their annotations for analysis and debugging
- **Prompts Management**: Create, list, update, and iterate on prompts
- **Datasets**: Explore datasets and synthesize new examples
- **Experiments**: Pull experiment results and visualize them with the help of an LLM
