+# PII Moderator Tool
+
+A complete toolkit to ensure your personal data never reaches LLM APIs.
+
+## Components
+
+1.  **Core API (`/api`)**: FastAPI server using Microsoft Presidio for high-accuracy PII detection and redaction.
+2.  **CLI (`/cli`)**: A developer-friendly tool to redact text or files from the terminal.
+3.  **UI Playground (`/ui`)**: A React-based web interface for real-time visualization of PII redaction.
+
+## Getting Started
+
+### 1. Start the API
+In one terminal:
+```bash
+cd api
+source venv/bin/activate
+python3 main.py
+```
+
+### 2. Use the CLI
+In another terminal:
+```bash
+cd cli
+source ../api/venv/bin/activate
+# Redact a string
+python3 pii_mod.py redact "Contact me at 212-555-0199 or email me at alice@example.com"
+```
+
+### 3. Launch the UI Playground
+In a third terminal:
+```bash
+cd ui
+npm run dev
+```
+Open `http://localhost:5173` in your browser.
+
+## Docker Usage
+
+The project is fully dockerized for development and production.
+
+### Development (Hot-reloading enabled)
+```bash
+docker compose up --build
+```
+- **API**: `http://localhost:8000`
+- **UI Playground**: `http://localhost:5173`
+- **Python CLI**: `docker compose run cli redact "Some text"`
+- **TypeScript CLI**: `docker compose run cli-ts redact "Some text"`
+
+### Production (Nginx + Optimized images)
+```bash
+docker compose -f docker-compose.prod.yml up --build
+```
+- **API**: `http://localhost:8000`
+- **UI Playground**: `http://localhost` (Port 80)
+
+- **Context-Aware Redaction**: Uses NLP (spaCy) to understand text context.
+- **Support for many entities**: Names, Emails, Phone Numbers, SSNs, URLs, IP Addresses, and more.
+- **Placeholder Replacement**: Swaps sensitive data with tags like `<PERSON>` or `<EMAIL_ADDRESS>`.
+- **CORS Enabled**: Ready for frontend integration.

+# React + TypeScript + Vite
+
+This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.
+
+Currently, two official plugins are available:
+
+- [@vitejs/plugin-react](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react) uses [Oxc](https://oxc.rs)
+- [@vitejs/plugin-react-swc](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react-swc) uses [SWC](https://swc.rs/)
+
+## React Compiler
+
+The React Compiler is not enabled on this template because of its impact on dev & build performances. To add it, see [this documentation](https://react.dev/learn/react-compiler/installation).
+
+## Expanding the ESLint configuration
+
+If you are developing a production application, we recommend updating the configuration to enable type-aware lint rules:
+
+```js
+export default defineConfig([
+  globalIgnores(['dist']),
+  {
+    files: ['**/*.{ts,tsx}'],
+    extends: [
+      // Other configs...
+
+      // Remove tseslint.configs.recommended and replace with this
+      tseslint.configs.recommendedTypeChecked,
+      // Alternatively, use this for stricter rules
+      tseslint.configs.strictTypeChecked,
+      // Optionally, add this for stylistic rules
+      tseslint.configs.stylisticTypeChecked,
+
+      // Other configs...
+    ],
+    languageOptions: {
+      parserOptions: {
+        project: ['./tsconfig.node.json', './tsconfig.app.json'],
+        tsconfigRootDir: import.meta.dirname,
+      },
+      // other options...
+    },
+  },
+])
+```
+
+You can also install [eslint-plugin-react-x](https://github.com/Rel1cx/eslint-react/tree/main/packages/plugins/eslint-plugin-react-x) and [eslint-plugin-react-dom](https://github.com/Rel1cx/eslint-react/tree/main/packages/plugins/eslint-plugin-react-dom) for React-specific lint rules:
+
+```js
+// eslint.config.js
+import reactX from 'eslint-plugin-react-x'
+import reactDom from 'eslint-plugin-react-dom'
+
+export default defineConfig([
+  globalIgnores(['dist']),
+  {
+    files: ['**/*.{ts,tsx}'],
+    extends: [
+      // Other configs...
+      // Enable lint rules for React
+      reactX.configs['recommended-typescript'],
+      // Enable lint rules for React DOM
+      reactDom.configs.recommended,
+    ],
+    languageOptions: {
+      parserOptions: {
+        project: ['./tsconfig.node.json', './tsconfig.app.json'],
+        tsconfigRootDir: import.meta.dirname,
