AI verification for
regulated industries

One API call verifies any AI output before it reaches your users. If your AI gets audited, Trusay proves you checked it.

The Problem
AI in regulated industries is confidently wrong.
LLMs inherit cognitive biases that cause real harm. And starting August 2026, regulators require you to prove your AI outputs are verified.
40–80K
Preventable adverse events per year in the US from diagnostic cognitive bias — the same biases LLMs amplify
Aug 2026
EU AI Act high-risk enforcement for credit scoring AI. Every fintech company in Europe needs verification infrastructure
95%
Alert override rate in rule-based clinical decision support. Alert fatigue makes traditional checking useless
1%
Of AI clinical outputs now include safety disclaimers — down from 26% in 2022. Models are getting more confident, not safer

What happens when AI is wrong
about a patient's diagnosis?

Real verification. Real error. Real correction.

How It Works
Three capabilities. One API.
Trusay uses a proprietary multi-probe verification engine to independently challenge AI outputs before they reach your users.
Per-Output Verification
Every AI output is independently challenged using multiple adversarial reasoning probes. If the probes disagree with the original output, it gets flagged for human review. Pass or flag in under 10 seconds.
Continuous Drift Monitoring
Batch-level tracking detects when your AI's reasoning quality degrades — before accuracy drops. Get alerts when your model enters a degraded state so you can intervene proactively.
Compliance Audit Trail
Every check is logged with timestamps, confidence scores, risk bands, and unique IDs. Exportable for EU AI Act, FDA, and Basel compliance audits. Retention from 7 days to 1+ years.

Industries
Built for where AI errors have consequences.
Same API. Same audit trail. Purpose-built for regulated environments where being wrong isn't an option.
Healthcare
Diagnostic probability, dosage calculations, drug interaction verification. Catches the base rate errors behind 40K+ adverse events per year.
FDA + EU AI Act
Financial Services
Credit risk probability, loan calculations, AML false positive assessment. Same math, same biases, same consequences.
EU AI Act Aug 2026
Pharmaceutical
Statistical significance interpretation, adverse event rates, clinical trial protocol verification.
ICH + FDA Guidance
Insurance
Actuarial calculations, claims probability, underwriting model verification. Audit-ready from day one.
EU AI Act Annex III
Legal
Deadline calculations, penalty computations, citation verification. Prevent the next Mata v. Avianca.
Bar AI Guidance
Research
Statistical test verification, numerical result checking, methodology validation for AI-assisted science.
Institutional Policy
Integration
Three ways to deploy.
A
Pre-Display Gate
Healthcare · High-Stakes Finance
AI output → Trusay verifies → Pass: show to user. Flag: show with warning and corrected answer. Catches errors before they reach the clinician.
B
Async Audit
Compliance · Research
AI outputs displayed normally. Trusay checks in the background. All results logged. Flags reviewed in compliance reports. Zero added latency.
C
Escalation Trigger
Finance · Legal · Engineering
Pass: auto-approve. Flag: route to senior analyst or human review queue. Automated triage for high-volume decision workflows.
