Jevinik
Stock terminal that gathers live evidence via Valyu and asks Jev for the probability a stock trades higher in 30 days.
Overview
Jevinik is a stock decision terminal with a Bloomberg-inspired interface. You enter a ticker (with autocomplete for common US and European stocks), the API validates it, and Valyu runs five evidence searches in parallel across market data, company news, industry news, analyst views and macro risks. Price history is condensed into returns, range, volume and recent-close statistics, and Jev evaluates the compact evidence state with typed boolean, score and choice questions.
The result shows the probability of a higher price in 30 days, an overall outlook, evidence quality, bullish, neutral or bearish signals by evidence category, the supporting sources, and separate timings for evidence retrieval, decision and end-to-end completion. Jev is called through Vercel AI Gateway, so no general-purpose generative model is used for the decision. SEC filings are currently disabled in the flow. It requires Node.js 20.9+, a Valyu key and a Vercel AI Gateway key.
What the decision model decides
| Type | Question | Answers |
|---|---|---|
| Yes / no | Will this stock trade higher in 30 days? | — |
| Choice | What is the overall outlook (bullish, neutral, bearish)? | bullish · neutral · bearish |
| Score | How strong is the evidence quality? | — |
