Inspect every decision.
Test every change.
JevScope turns structured AI decisions into inspectable, repeatable engineering evidence. Edit questions, inspect probabilities, run case sets, and compare policies in a local workbench.
Decision inspector
See the selected choice, full probability distribution, expected score and rubric, or raw YES probability for noul questions.
Batch & regression
Import JSONL cases, check explicit expectations, and review latency, confidence, and policy buckets.
A/B comparison
Run the same cases against two definitions and see changed decisions, confidence movement, and expectation results.
Start with your own decisions
Install Node.js 20+ and pnpm, set a TypeSafe API key in the local API process, then launch the workbench.
git clone https://github.com/jeiel85/jevscope.git cd jevscope cp .env.example .env # Set TYPESAFE_API_KEY in .env pnpm install pnpm dev
The Studio runs locally. Live evaluations send your state and questions to TypeSafe AI through the local API server. The API key is never included in the browser bundle. This public page is an overview, not a live provider demo.
