PrivacyScrubber vs Cloud AI Gateways
Pre-TLS Local RAM, No-Code Document App & Polyglot SDK vs Questa AI, Superwise Sentinel & Amaze
Compare PrivacyScrubber vs Questa AI, Superwise Sentinel, and Amaze: pre-TLS local RAM sanitization, no-code document OCR, Python MCP, and <1ms SDK.
Verdict: PrivacyScrubber unifies Pre-TLS Browser DLP, a Turnkey No-Code Document App, and a <1ms Polyglot SDK with Zero Cloud Proxy Routing
When evaluating alternatives to Microsoft Presidio, teams often split between deployed AI Gateways (like Questa AI or Superwise Sentinel) that route prompts through central proxy layers, and ready-made no-code document apps (like Amaze). PrivacyScrubber delivers all three in a single zero-trust architecture: (1) a Manifest V3 Chrome Extension that sanitizes ChatGPT, Claude, and Gemini prompts pre-TLS in local RAM; (2) a turnkey No-Code Web Workspace for PDF, DOCX, CSV, and offline OCR; and (3) a <1ms Node.js/TypeScript SDK and Python PyPI MCP server.

Technical Architecture: Pre-TLS Edge RAM Sanitization vs Central AI Proxy Gateways
Organizations looking beyond Microsoft Presidio typically encounter two categories of tools: AI Security Gateways (such as Questa AI and Superwise Sentinel) that act as an intermediary proxy between users/CLIs and LLM providers, and No-Code Ready-Made Apps (such as Amaze) designed for non-technical teams redacting local documents and national IDs.
While AI proxy gateways offer centralized request logging, routing cleartext prompts and CLI traffic to a proxy gateway means sensitive data still leaves the endpoint before sanitization — introducing network latency and creating a central honeypot of sensitive corporate prompts. Conversely, standalone no-code document apps lack inline browser DOM interception for ChatGPT/Claude and lack sub-millisecond developer SDKs.
PrivacyScrubber bridges both worlds under the Zero-Trust Data Sanitization (ZTDS™) protocol:
- Versus Questa AI & Superwise Sentinel (AI Gateways): PrivacyScrubber intercepts prompts directly inside the browser DOM and local CLI/MCP (
pip install privacyscrubber-mcp) in <1ms in local RAM before TLS transmission. Placeholder mappings ([NAME_1],[ID_2]) stay strictly in volatile client RAM, and TEAMS Governance ($99/mo flat) enforces centralized custom rules and cryptographic compliance receipts without routing cleartext through a proxy server. - Versus Amaze (No-Code Document App): PrivacyScrubber's Offline Browser Document & OCR Workspace lets non-technical HR, legal, and finance teams drag-and-drop PDF, DOCX, XLSX, and CSV files in Airplane Mode, covering 30 specialized industry profiles and international national IDs (including Polish PESEL, German Steuer-ID, UK NHS, Israeli TZ, and US SSN).

Frequently Asked Questions
How does PrivacyScrubber compare to Questa AI and Superwise Sentinel?
Questa AI and Superwise Sentinel operate as AI security gateways that manage and proxy traffic heading to LLMs across browser, desktop, or CLI. PrivacyScrubber enforces pre-TLS Zero-Trust Data Sanitization (ZTDS™): prompts and CLI/MCP payloads are tokenized in <1ms inside local device RAM before any network packet leaves the machine, eliminating proxy routing latency and central cleartext request logging while providing $99/mo flat TEAMS governance.
How does PrivacyScrubber compare to Amaze for no-code document and local ID redaction?
Like Amaze, PrivacyScrubber gives non-technical teams a ready-made, zero-code application to redact documents without writing Python code, including built-in support for regional and national identifiers (such as Polish PESEL, EU IBAN, UK NHS numbers, and US SSNs). In addition to offline PDF/DOCX/Excel/OCR document scrubbing, PrivacyScrubber also includes a real-time Chrome Extension for ChatGPT/Claude/Gemini and a <1ms Developer SDK.
Does PrivacyScrubber support CLI, IDE, and team placeholder rules like Superwise Sentinel?
Yes. Developers and CLI users run npx ztds-audit or pip install privacyscrubber-mcp for local stdio MCP sanitization in Cursor, Claude Code, and terminal workflows, while TEAMS ($99/mo flat) provides centralized custom placeholder rules and encrypted Argon2id + XChaCha20-Poly1305 session handoff across the organization.
