Protect PrivacyPreserve Meaning

Document redaction built for the AI era.

Readable, AI-Ready Output

Smart aliases preserve context so documents stay usable for downstream AI workflows.

100% Local Processing

Redaction runs entirely in your browser, with no remote API handling your sensitive data.

Consistent and Auditable Results

Deterministic redaction pipeline produces results you can review, repeat, and defend.

The Challenge

Using AI on sensitive documents should not require a tradeoff

You want to use tools like ChatGPT or Claude on contracts, MSAs, and other sensitive documents. But you cannot send raw client names, PII, or financial data to a cloud model.

The obvious workarounds both fail.

Legacy RedactionLLM Redaction
Destroys meaningBlack bars, brittle OCR, and broken references strip away the context AI needs.
Creates exposure & inconsistencySensitive source data goes to the cloud first, while outputs can vary across runs.

What is missing

A secure way to prepare documents for AI without sacrificing either privacy or meaning.

The Solution

Built uniquely for the AI era.

CleanPrompt gives you the best of both worlds: the absolute security of local processing, and the semantic perfection required for downstream LLM analysis.

It is the unified redaction engine designed specifically to safely bridge your private documents with modern AI tools.

The RequirementCleanPrompt
Semantic Continuity
Replaces private data with smart aliases to preserve exact grammatical flow.
Zero Data Leakage
Executes 100% locally in your browser. Unredacted data never touches the cloud.
Perfect Repeatability
Uses a deterministic, auditable pipeline rather than unpredictable LLM inference.
Legal Compliance
Built for privacy-sensitive workflows, including support for GDPR, HIPAA, CCPA, and APP standards.

About

The Origin Story

CleanPrompt was born out of personal workflow frustration. As a commercial advisor to business and government clients, I deal with highly confidential data every day. I know firsthand that strict privacy is the non-negotiable foundation of trust.

But as an AI power-user, I also know the immense leverage LLMs bring to complex knowledge work. After spending countless hours manually sanitizing contracts—painstakingly replacing names and entities to make them safe for AI without breaking their context—it became clear the process was painfully unscalable.

I built CleanPrompt because professionals shouldn't have to manually bridge that gap. We needed a purpose-built, secure-by-design redaction engine that lets you keep your clients' trust while harnessing the power of modern AI.

Buying Paths

Need shared accountability or a higher-assurance rollout?

Start with Free if you are evaluating the core workflow. Move to Pro when the redaction loop becomes recurring solo work. Move to Business when you need per-user team billing, centralized billing, Redaction Manifest (JSON), and admin audit trails. Move to Enterprise when you need approvals, attestations, SSO or role-based access, or policy controls.
