Question 1

What is JanfioLayer?

Accepted Answer

JanfioLayer is a complete AI evaluation platform with six tools: Prompt Playground, Projects, Evaluations, Compare Evaluations, Regression Testing, and Golden Datasets. It combines automated scoring with human-in-the-loop review to catch failures in LLMs, RAG pipelines, copilots, and agents before they reach production.

Question 2

What is the Prompt Playground?

Accepted Answer

A standalone scratchpad where you can paste any system prompt and model output to get instant correctness, reasoning, and safety scores — plus a SHIP/REVIEW/BLOCK production decision. No project setup required.

Question 3

What does the free pilot include?

Accepted Answer

100 free evaluation credits with no credit card required. Full access to all platform features including the Prompt Playground, Projects, Evaluations, Compare Evaluations, Regression Testing, and Golden Datasets. A sample project is pre-loaded so you can explore immediately.

Question 4

What are Golden Datasets and Regression Testing?

Accepted Answer

Golden Datasets are curated ground-truth benchmarks built from your best evaluation examples. Regression Testing runs these datasets against any model or prompt change to automatically detect quality drops before you ship to production.

Question 5

How does Compare Evaluations work?

Accepted Answer

Compare Evaluations gives you a side-by-side view across tasks, models, prompts, or time periods. You can instantly quantify regressions and improvements to make model and prompt decisions backed by data.
