Building with large language models means constantly testing—swapping prompts, comparing model outputs, and measuring what actually works. Chatter and Luel both sit in the AI development workflow, but they solve different problems at different stages.
Chatter is built for the iteration phase: you're comparing prompt variations, testing GPT against Claude against Llama, and tracking metrics before you ship. Luel works upstream—it turns your user interactions and conversations into labeled datasets you can use to train or fine-tune custom models.
If you're evaluating which tool fits your pipeline, the choice depends on where you are: still experimenting with existing models, or building training data for something proprietary.
Choose Chatter for LLM testing and iteration, or Luel for converting user actions into labeled training datasets.
Chatter is ideal for developers and AI engineers who need to test, iterate, and refine LLM prompts before production deployment.
Luel is best for data teams and AI practitioners who require structured, labeled training datasets from user interactions for custom AI models.
