Automated README summary
Automatically summarized from the README on 20 Sept 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
A local web tool for developers evaluating TypeSafe AI's Jev model: paste a state, define typed questions, and see each answer with its full probability distribution plus the raw request/response bytes.
How it uses Jev
The Express backend calls the TypeSafe HTTP API directly with a state and a questions object. Jev returns per-question answers with probability distributions; the UI renders noul as a 0→1 probability with a 0.5 midpoint line, choice as selected option plus per-option probabilities, and score as a probability-weighted mean with tier distribution.
Primitives:choicescorenoul
Technique worth stealing
Skip the official SDK and call the HTTP API raw, so the UI shows exactly the bytes sent and received.
Try it
Node.js 20+; npm install, write TYPESAFE_API_KEY and PORT to .env.local, npm start, open localhost:5180.
Model judgments from README excerpts
Project signals use repository metadata, an existing summary and the first 700 README characters, not the full project. “Not found” means not detected in that material; it does not establish absence. These are the original judgments with recorded models and dates, not source audits or run results.

Evidence
These signals use repository metadata, an existing summary and at most 700 cleaned README characters. ≥ 0.60 means reported in that excerpt; ≤ 0.40 means not found there. The middle band is inconclusive. None is a source-code audit or a test result. The runnable-tool question excludes research experiments; the recommendation question asks for a learning shortlist, not a quality verdict.
