🛡️ Objective AI Verification • 100% Client-Side Privacy

Stop Guessing If Your AI Is Hallucinating.

Q: How does TruScore detect hallucinations in AI responses?

TruScore runs real-time epistemic NLP verification directly inside your browser. It calculates the statistical density of epistemic hedging, flags deceptive certainty without verified evidence, and cross-references citation formats, dates, and quantitative markers to produce a calibrated 1 to 10 confidence score.

Q: Does TruScore store or transmit my private prompts and conversations?

No. TruScore executes 100% locally in your browser using client-side JavaScript within Chrome's V8 engine. Your prompts, confidential text, and AI responses never leave your device or get sent to any external server.

Q: What is the Pro Prompt Doctor?

Prompt Doctor is a specialized diagnostic engine. When an AI produces a low or moderate score, it identifies why the prompt caused the model to hallucinate or hedge, and constructs a 1-click optimized rewrite that forces the model to give a grounded answer.

Q: Which AI platforms are compatible with TruScore?

TruScore is natively compatible with ChatGPT (chatgpt.com & chat.openai.com), Claude (claude.ai), and Google Gemini (gemini.google.com) on Google Chrome, Microsoft Edge, and Brave.

TruScore injects a calibrated 1–10 confidence score directly beneath ChatGPT, Claude, and Google Gemini responses. Spot fabricated citations, deceptive certainty, and epistemic hedging in real time—then cure flawed prompts with 1-click Prompt Doctor.

SUPPORT & ANSWERS

Frequently Asked Questions

Everything you need to know about TruScore, AI verification, and privacy.

How does TruScore detect hallucinations in AI responses?

TruScore runs real-time epistemic NLP verification directly inside your browser. It calculates the statistical density of epistemic hedging ("I think", "arguably"), flags deceptive certainty (claims presented as absolute fact without verifiable empirical evidence), and cross-references citation formats, dates, and quantitative markers to produce a calibrated 1–10 confidence score.

Does TruScore store or transmit my private prompts and conversations?

No, 100% Client-Side Privacy. All evaluation algorithms execute locally within your browser's V8 engine. Your prompts, confidential documents, and AI conversations never touch our servers or leave your computer.

What is the Pro Prompt Doctor?

When an AI gives a low or flawed response, Prompt Doctor analyzes the prompt's cognitive trigger (e.g., asking for future speculation or lacking boundary constraints) and provides a 1-click rewritten prompt that forces the model to give a grounded, accurate answer immediately.

Which AI models and web platforms are supported?

TruScore is natively compatible with ChatGPT (chatgpt.com & chat.openai.com), Claude (claude.ai), and Google Gemini (gemini.google.com). Because TruScore audits the output text stream rather than model dropdowns, it works seamlessly with GPT-4o, Claude 3.5 Sonnet, Gemini 1.5, and all future models.

Where do I find my license key after purchasing?

After checkout, your license key is included in your confirmation email receipt (format: PLUS-XXXX... or PRO-XXXX...). Paste it into the activation box on this website or inside the TruScore extension popup and click Activate Key.

How do I update my payment card, view invoices, or cancel?

You have complete 24/7 self-service control via the Customer Billing Portal ↗. You can view VAT receipts, switch plans, update payment cards, or cancel anytime with a single click.
