Zero-Knowledge Architecture

Secure AI Document Analyzer

Plain-language breakdown of any contract, lease, or agreement — with red flags highlighted. Your files never leave your browser.

AES-256 encrypted
Zero data retention
Commercial API — not ChatGPT

How It Works

Three steps. No account required. Free to start.

1

Upload your PDF

Text is extracted locally in your browser. The file itself is never uploaded to any server.

2

AI analyzes the text

Extracted text is sent via AES-256 encryption to our commercial AI API — never stored or used for training.

3

Get a plain-language breakdown

Structured results with key terms, obligations, rights, and red flags — no legal jargon.

Your documents are never stored

Other tools upload your files to their servers. We don’t.

Why this is safer than pasting into ChatGPT

When you paste a contract into a consumer chatbot, that text is stored in your conversation history, may be retained for years, and can be used to train future AI models. We built a different pipeline.

Your PDF never leaves your browser

Text is extracted locally using WebAssembly. The file itself is never uploaded, transmitted, or touched by our servers. Only the extracted text is sent for analysis.

Commercial API — not a chatbot

We use Anthropic’s commercial API where training on your data is contractually prohibited. No conversation history. No account with the AI provider. No data retention.

AES-256 encrypted transmission

Every API call uses bank-grade TLS encryption. Text is encrypted in transit, processed, and immediately discarded. Nothing is stored on any server at any point.

No account required

Analyze up to 3 documents per day without creating an account or handing over your email. No signup wall between you and understanding your contract.
