Quick Answer
Cleardox only anonymizes documents — permanently removing sensitive data before people read them. It's built for legal, compliance, and records-release workflows.
Questa AI does both: it anonymizes documents and anonymizes data in real time before it reaches an AI model (ChatGPT, Claude, Gemini, Copilot, Azure OpenAI), then automatically restores it for authorized users. It also gives customers full control over where their data is hosted — self-hosting in any region or system — which Cleardox doesn't offer.
Bottom line: Choose Cleardox if you only need document anonymization. Choose Questa AI if you need document anonymization, AI anonymization, and data residency control in one platform.
Core Difference
Cleardox and Questa AI both help organizations protect sensitive information, reduce privacy risk, and support compliance — which is why teams often compare them. The difference is what happens after sensitive data is protected.
Cleardox is built for document workflows. You upload a file, identify confidential information, permanently redact it, and export a version safe to share with people.
Questa AI is built for AI workflows — as well as documents. Instead of just preparing documents for people, it prepares prompts, structured data, and API requests before they reach an AI model. Sensitive information is tokenized in real time, processed safely, and automatically restored in the response for authorized users.
One protects documents before people read them. The other protects data before AI models process it — and does both.
This distinction matters because redaction and anonymization aren't the same thing: redaction permanently removes sensitive information from a document. Anonymization temporarily replaces it with a substitute value so it can be safely processed, then restores it for authorized users afterward. Cleardox only redacts documents. Questa AI does both — using the same detection and tokenization engine for files and for live prompts, API calls, and AI responses.
The two products often complement each other in practice: a legal team might use Cleardox to prepare filings while engineering uses Questa AI to protect data flowing through an internal AI assistant.
Key Terms
PII
Data that can identify a person (name, email, account number, etc.)
PHI
Health information tied to an identifiable person, regulated under HIPAA
PCI
Cardholder data (card numbers, expiration, CVV), governed by PCI DSS
Tokenization
Replacing a sensitive value with a meaningless placeholder — unlike redaction, this can be reversible
Redaction vs. anonymization
Redaction permanently removes data. Anonymization temporarily replaces it, then restores it for authorized users
Data minimization
Exposing only the minimum personal data necessary for a task
AI Governance
Policies and controls for how AI systems access and use data
Runtime anonymization
Protecting data at the moment it's used — inside a live prompt or API call — not just within stored documents
Safe AI agent
An agent with guardrails, permission boundaries, and human-approval checkpoints

Pricing
Both products' pricing varies by deployment and volume, but Questa AI typically runs 3–5x cheaper than Cleardox at comparable usage, largely because it starts with a free trial and low-cost pay-as-you-go credits instead of a fixed subscription floor.
| Factor | Cleardox | Questa AI |
|---|---|---|
| Entry point | Paid subscription tiers; no free trial | Free Blackbox trial + 100 free developer credits |
| Pricing model | Per-document/page or subscription tiers | Usage-based credits, starting at $10, or platform subscription. Usually Questa is 3-5X cheaper at comparable usage due to lesser reliance on cloud based processing and evergreen pay as you go credits instead of an expensive monthly subscription |
| Cost driver | Number of documents/pages processed | Number of API requests, tokens, or fields processed |
| Self-hosted / on-prem | Not confirmed | Included as a deployment option |
| Add-on costs | Human review workflow seats | Governance module, Safe Agent guardrails, multi-LLM routing |
| Best for | Small, fixed-volume document teams | Any volume — scales down for small teams, up for enterprise |

OursData Sovereignty with Any Model
Questa AI can provide 100% core data sovereignty anywhere in the world due to its AI first architecture while giving complete flexibility to use any AI models on the anonymized data sets. Several critical infrastructure customers in healthcare, finance and other fields with High Risk or Critical Risk within European Union, United States, India and Australia are implementing Questa with local data governance rules while using any Model after anonymization. This compliance with flexibility to choose models is unmatched.

CRM / Source ApplicationCleardox doesn't sit in this live data path. It operates upstream, on static documents, before they're shared with people — one-time, batch processing with no reversibility (redaction is permanent). Questa AI operates both on stored documents and inline in the live request path, at millisecond-level latency, with a token vault for re-identification.
