Why the comet?
Direction, focus and evidence at the core.
The comet represents evidra AI cutting through market noise to surface evidence-backed research signals. The stars represent the AI intelligence layer, and the central ring reflects the evidra Score at the heart of the platform.
AI intelligence
AI helps explain calculated signals and patterns in clearer language, while the underlying score remains evidence-led.
Evidence at the core
The evidra Score turns multiple categories of public market evidence into a research-interest signal with visible caveats.
What it does
A simpler way to screen the S&P 500.
Reviewing the full S&P 500 manually takes time. evidra AI narrows the field by highlighting companies with interesting evidence patterns, then explains the factors in clear language.
01
Scan the market
Review ranked research signals across the S&P 500, with labels designed to indicate research interest rather than investment suitability.
02
Understand the evidence
See the underlying factors behind each signal, including price movement, fundamentals, insider activity, institutional changes and company events.
03
Research further
Use AI-generated summaries to understand the signal quickly, then make your own judgement using independent research.
The engine underneath
Structured scoring, explained in plain English.
The score is calculated by a deterministic research model. AI does not casually invent the score; it helps explain the calculated result, evidence and caveats in a format that is easier to understand.
+
Positive evidence
Factors that may make a company more interesting to research, such as improving momentum, recent evidence strength or supportive fundamentals.
!
Caution factors
Risk and context signals are surfaced alongside positives, so the user can see why a company may still require careful review.
✓
Confidence and recency
The model considers how complete, current and useful the available evidence is before presenting the final research label.
