FAQ
How does the A/B testing work?
You define prompt variants in the dashboard, then our SDK automatically splits traffic across variants in your users' conversations. We collect response data via webhooks and score quality using ML models.
What AI providers are supported?
PromptAB is provider-agnostic. It works with OpenAI, Anthropic, Cohere, or any LLM API. You integrate our lightweight SDK and we handle the routing and analytics layer.
How is response quality measured?
We use a combination of ML-based semantic scoring, user satisfaction signals (thumbs up/down, session length, follow-up rate), and custom conversion events you define for your product.
