Zero-Data Architecture
DOMAIN RIGOR CALIBRATION

Calibrated to Your Professional Truth Standard

Different industries demand different epistemic rigor. Select a domain below to see how TruScore adapts:

⚖️

Legal & Regulatory Persona

Penalizes phantom citations, vague qualifiers, and ambiguous contractual commitments.
HIGH RISK SECTOR
⚠️ The Hallucination Hazard:
LLMs frequently fabricate fictitious federal appellate decisions, nonexistent court case names, or quote non-existent statutes with total linguistic confidence.
Real Consequence: Court sanctions, judicial reprimands, and legal malpractice liability.
🛡️ How TruScore Protects You:
TruScore scans citation syntax and applies strict mathematical penalties to evasive phrasing. If an LLM invents a case citation or lacks statutory precision, the score drops below 4.0 instantly.
Outcome: Verified brief drafts and ironclad contract clauses before client filing.
COMPARISON

Working With AI: Before vs After TruScore

Transform your AI workflow from anxious second-guessing into audited certainty:

❌ Without TruScore
  • ❌ Blind Faith in Fluent Prose: Believing articulate AI outputs that covertly invent statistics, dates, or non-existent citations.
  • ❌ Hours of Manual Fact-Checking: Manually opening 10 browser tabs to verify whether an AI assertion is fact or fiction.
  • ❌ Covert Hedging Ignored: Overlooking sneaky disclaimers like "I believe" or "take this with a grain of salt".
  • ❌ Repeating Prompt Mistakes: Asking vague, open-ended questions that repeatedly trigger AI hallucinations.
✓ With TruScore Installed
  • ✓ Instant 1–10 Confidence Badge: Objective rating appears right beneath every response in ChatGPT, Claude, Gemini, and Copilot.
  • ✓ Zero-Friction In-Page Forensic Audit: See factual grounding, epistemic hedging, and coherence breakdowns in under 10ms.
  • ✓ Color-Coded Claim Highlighting: Green anchors, amber hedging, and red risk callouts directly on the chat page.
  • ✓ Context-Aware Prompt Doctor: Analyzes multi-turn conversation history to resolve pronouns ("that", "it") and brief follow-ups ("why?") into context-complete, hallucination-resistant prompt rewrites.

PRAISE

Trusted by High-Stakes Professionals

What lawyers, researchers, and engineers say about having a live truth meter in chat:

"In appellate litigation, citing a hallucinated ruling will get you sanctioned immediately. TruScore's Legal Persona caught three fabricated federal district court citations in a single brief draft. It has become essential infrastructure for our firm."

ES
Elena S., Esq.
Partner · Commercial Litigation

"We run meta-analyses on genomic clinical trials. When Claude summarizes complex trials, TruScore flags any unsourced patient cohorts or synthesized statistics in red. The Prompt Doctor feature saves us 30 minutes per query."

DR
Dr. Marcus Vance
Lead Computational Biologist

"The 10ms zero-server latency is the killer feature. Our enterprise compliance team strictly forbids sending internal engineering code to external APIs. TruScore running 100% locally inside Chrome passed our security audit on day one."

QUESTIONS & ANSWERS

Frequently Asked Questions

Everything you need to know about TruScore's epistemic scoring engine and Chrome extension:

How does TruScore evaluate AI confidence in real time?
TruScore uses a proprietary client-side verification engine that audits AI outputs instantly as they stream onto your screen. By performing multi-dimensional truth and epistemic certainty analysis locally within your browser, TruScore scores responses in milliseconds without introducing latency or transmitting your data to external servers.
Does TruScore store or read my private conversations?
Never. TruScore operates with 100% client-side privacy directly on your machine. Your prompts, proprietary company data, and AI responses are never transmitted to external servers, logged in databases, or used for model training.
What is the Context-Aware Prompt Doctor and how does it work?
Don't just detect hallucinations—cure them. When an AI response scores low or moderate (< 7.0/10), Pro Prompt Doctor diagnoses structural flaws in your original prompt and delivers an airtight, optimized rewrite with 1 click to ensure grounded, verifiable answers immediately.

🔗 Multi-Turn Context-Aware Resolution: Unlike basic prompt tools that only examine your single last input, TruScore inspects preceding conversation turns. If you ask a brief follow-up like "why?" or "give me 3 examples of that", Prompt Doctor resolves what "that" refers to, pulling the core topic forward to craft a self-contained, citation-anchored rewrite that eliminates prompt drift and circular hedging across multi-turn chats. (Only available on the Pro Plan)
Which AI platforms are currently supported?
TruScore integrates natively across ChatGPT (chatgpt.com & chat.openai.com), Claude (claude.ai), Google Gemini (gemini.google.com), and Microsoft Copilot (copilot.com).
What happens if I reach my monthly audit allowance?
If you exhaust your Plus (300 audits/month) or Pro (1,500 audits/month) quota, TruScore gracefully switches to the rolling Free Tier (10 audits per 24 hours) until your next billing cycle refreshes. You can also upgrade your plan or add team seats anytime from the pricing section or your billing portal.
What are Domain Rigor Personas and how do they work?
Domain Rigor Personas calibrate TruScore's auditing engine to the specific standards of your field:
  • 🌐 Standard General: Balanced factual consistency and clarity check for everyday queries.
  • 🔬 Strict Academic & Scientific: Rigorously verifies literature citations, empirical data, and peer-reviewed rigor.
  • ⚖️ Legal & Compliance: Strictly penalizes contractual ambiguity, disclaimers, and passive hedging.
  • 💻 Software & Technical: Inspects code syntax, implementation completeness, and API accuracy.
⚡ Available on the Pro Plan.
Where do I find my license key after purchasing?
