Automated README summary
Automatically summarized from the README on 24 Sept 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
A 3D Magic 8 Ball web app where you hold, shake, and release the ball to get an answer to your question. Jev, TypeSafe's decision model, picks among the 20 classic answers and returns a probability for each.
How it uses Jev
One Convex action sends your question to Jev through the Convex AI Gateway. Jev makes a Choice over the 20 classic answers. The page shows Jev's probability for every answer and displays the highest-probability one, because rounded probabilities occasionally disagree with the reported choice.
Primitives:choice
Technique worth stealing
Show the full probability distribution and display the highest-probability answer when the reported choice disagrees.
Try it
npm install; npx convex dev; npm run dev
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.
