Built for prop firms

01 / 03

Interview.

A voice interviewer that listens like your sharpest analyst.

Every trader gets the same rigorous conversation, in their own language, at the hour that suits them. Rubi adapts each question to what the trader just said and to what their account actually did.

  • Adaptive AI voice interviewer in 82 languages, with an optional live avatar
  • Follow ups on vague answers, probes built from the trader's own trade history
  • Every answer transcribed and translated to English for your team

Detect.

Evidence, not vibes. Every signal is timestamped.

The session is recorded from webcam and the full screen. Integrity events are logged to the millisecond, then weighed against deterministic floors computed from real trading activity.

  • Webcam plus entire screen recording, synchronized on one clock
  • Integrity signals: tab switches, paste events, screen share stops, blank camera
  • Trading risk checks based on actual activity from Axcera or your own API

Decide.

One sentence verdict. Your analyst signs it.

Rubi hands your risk team a recommendation it can defend: a clear next step, the evidence behind it, and room for human judgement. Every decision you record sharpens the next report.

  • A one sentence verdict with a recommended next step
  • Evidence bullets that link back to the exact moment in the recording
  • Human decision first, and a learning memory scoped to your firm

Six instruments, one verdict.

A structured core of topics, then follow ups chosen live from the answer and from the account. Wrap up is planned so the trader always finishes.

Learning memory

When an analyst corrects the AI (over flagged, under flagged, the behaviour confirmed), that precedent informs the next interviews and reports. Per firm, never shared across tenants.

How it works

From invite to verdict, in one thread.

  1. 01

    Invite link

    Create an interview from the dashboard, the API or a trader profile. Rubi issues a single use link valid 24 hours to 7 days.

  2. 02

    Interview

    about 20 minutes, capped at 60

  3. 03

    Report

    Transcripts, integrity events and synced trades are cross checked. The report lands with a risk score, verdicts and evidence.

  4. 04

    Decision

FAQ

Prop firm anti-fraud, answered.

What is a prop firm anti-fraud system?

A prop firm anti-fraud system helps risk teams check whether the person who requests a payout is the one who traded the account. Rubi does this with an AI video interview, integrity signals, and a cross-check against real trades before money leaves the firm.

What fraud does Rubi detect for prop firms?

Rubi reports three concern verdicts: third-party trading (including EAs, signal copiers and account managers), cross-account hedging, and gamification such as all-in sizing or martingale recovery. Each verdict is Clear, Suspected or Likely, with evidence linked to the recording or the trades.

Does Rubi reject traders automatically?

No. Rubi recommends a next step and shows the evidence. Your analyst makes and records the decision. That feedback calibrates future reports for your firm only.
