A safeguard between you and the AI ยท V3.1.2

Keep sensitive info out
of your AI prompts.

GC Protect sits between you and the AI. Before you hit send, it detects supported sensitive data in your prompt and replaces each value with a token. The AI gets a usable prompt. Your real data stays in your browser.

Works on ChatGPT, Claude, Gemini, and Grok. For professionals, teams, and anyone who types real information into AI tools.

CRITICAL RISK
Hey I'm getting an error in my API. Here's my config: API_KEY=sk-proj-abc123def456ghi789jkl012 DB_URL=postgres://admin:mypassword123@db.company.com:5432/production GitHub token: ghp_xK9mN2pQ4rS6tU8vW0yZ3aB5cD7eF AWS Access Key: AKIAIOSFODNN7EXAMPLE Can you help me debug?
๐Ÿงช Synthetic test data only. Uses the same detection logic as the V3.1.2 extension. Last verified 2026-10-22.
WHAT V3.1.2 SHIPS

Three features we got right.

Honest about what works. Verified 2026-10-22.

MODE TOGGLE
๐Ÿ”’ Strict or โœจ Personal

Choose per session. Strict sends only tokens to the AI. Personal does the same, plus restores real names on your screen when the AI responds.

STRICT
Dear โŸจGC-C...โŸฉ, your invoice...
PERSONAL
Same prompt sent, "Dear Jane Doe" on your screen
PROOF PANEL
โœ“ See exactly what was replaced

After every Protect & Send, a panel slides in showing each field we detected and the token the AI received. Real values are masked.

UNIVERSAL COMPATIBILITY
๐Ÿ›ก๏ธ Works the same on every AI

Same detection, same tokenization, same restoration across every supported platform. No AI-specific hints that could trigger refusals.

โœ“ ChatGPTโœ“ Claudeโœ“ Geminiโœ“ Grok

See the full compatibility log + release notes in your dashboard after signup โ†’

Plus: 17 detection types across credentials, PII, healthcare, and financial fields. Transparency panel for browser vault inspection. Deterministic tokens so the same value gets the same token within a session.
HOW IT WORKS

Your workflow stays the same.

โœ๏ธ
You type a prompt with real data

Normal workflow. Paste client info, patient details, API keys โ€” whatever you need.

๐Ÿ›ก๏ธ
GC Protect scans before you send

Supported sensitive fields are replaced with cryptographic tokens in under a second. Unique per session.

๐Ÿ‘€
You review and send

A panel shows exactly what was detected and replaced. Review the remaining text, then click Protect & Send.

๐Ÿค–
AI responds using tokens

The AI gives a complete answer using the tokens as placeholders. It never saw your real data.

โœ…
Real values restored on your screen

In Personal mode, GC Protect swaps tokens back to real values when displaying the response. Only you ever see them.

๐Ÿ“‹
Metadata logged to your audit log

Timestamp, platform, risk score, field counts โ€” no prompt content, no values. Exportable to CSV.

WHO USES IT

Anyone whose work touches real data.

If you type names, numbers, credentials, or client information into ChatGPT, Claude, Gemini, or Grok โ€” GC Protect is for you. Individuals, professionals, teams, and businesses.

โš–๏ธ
Lawyers

Keep client names and case details out of AI prompts while drafting.

๐Ÿฅ
Healthcare workers

Patient names, DOBs, and insurance IDs replaced before AI sees them.

๐Ÿ“Š
Accountants

SSNs, salaries, and tax info stay out of third-party AI tools.

๐Ÿ’ป
Developers

API keys, database URLs, GitHub tokens, and AWS credentials caught before they reach AI.

๐Ÿ 
Real estate

Buyer and seller info protected across every AI prompt.

๐Ÿ’ผ
Small businesses

Invoice data, bank accounts, and client info stay private when using AI for writing.

๐Ÿฆ
Financial advisors

Portfolio data and account numbers stay in your firm โ€” not in AI platforms.

๐Ÿง‘โ€๐Ÿ’ผ
Consultants & freelancers

Client contracts and project details tokenized before AI drafts.

HOW WE HANDLE DATA

Clear limits. Open source.

๐Ÿ”’
Prompt content stays in your browser

Tokenization runs locally in the extension. Original prompt text is never sent to Gratia Core Enterprise LLC servers.

๐Ÿ—‚
Only metadata is synced

Timestamps, platform name, risk score, field counts, and action taken. Never the actual values or prompt content.

โšก
Vault clears when you close the tab

The token-to-value map lives in browser memory only. Nothing persists after the tab closes.

๐Ÿ“‚
Open source โ€” audit the code

Full extension source on GitHub under MIT license. A privacy tool nobody can audit is a promise, not privacy.
