# Clone the repository
git clone https://github.com/nerveband/content-checkmate.git
cd content-checkmate

# Install dependencies
npm install

# Set up environment (for server-side proxy)
cp .env.example .env.local
# Edit .env.local and add your GEMINI_API_KEY

# Start development server
npm run dev

Community mode works out of the box with the server-side proxy. For own-key mode, users can enter their Gemini API key directly in the browser UI.

For the server-side proxy, set the GEMINI_API_KEY environment variable:

GEMINI_API_KEY=your_gemini_api_key_here

1. Upload Media: Drag & drop or click to upload an image
2. Add Context: Enter description, CTA, and post intent
3. Set Exclusions: Select any content to exclude from flagging
4. Analyze: Click "Analyze Content" to get results

• Compliant: No issues found
• Low Risk: Minor issues, mostly compliant
• Medium Risk: Notable issues requiring attention
• High Risk: Serious violations requiring immediate action

1. Upload a source image (optional)
2. Enter editing instructions in natural language
3. Generate AI-modified images

npm run build

Set GEMINI_API_KEY as an environment variable in your Netlify dashboard. The app uses @sveltejs/adapter-netlify and Netlify Blobs for rate limiting.

Swap adapter-netlify for adapter-node in svelte.config.js for any Node.js hosting environment. Rate limiting will use an in-memory store.
