# NoAI

> Browser-only deterministic redaction for preparing documents before they are shared with external AI tools.

NoAI helps people and small teams reduce obvious privacy risk before pasting document text into AI assistants. The app reads supported files locally in the browser, applies rule-based redaction, and exports reviewed Markdown. NoAI's redaction path does not upload document contents, does not call an AI model, and does not use analytics or telemetry that can inspect document text.

## Key Facts

- NoAI is a static web app intended to run in a modern browser.
- The redaction path is deterministic and rule-based, not AI-based.
- Supported inputs include Markdown, plain text, Word documents, and text-based PDFs.
- Markdown is the primary export format because it is easy for AI assistants and agents to read.
- Batch processing and combined Markdown export are core workflows.
- NoAI is not a legal-grade redaction system and cannot guarantee perfect anonymization. Users should review output before sharing it.
