🔑 Setting up AI

1. Get an API key:

   • OpenAI: platform.openai.com/api-keys
   • GitHub Marketplace Models: github.com/marketplace/models

2. In Notiva, click the 🔑 button in the editor toolbar (or AI Chat → Set API Key)

3. Paste your key and click Save Key

4. Your key is immediately XOR-encoded with a device fingerprint and stored in localStorage. It cannot be recovered by inspecting the HTML, localStorage, or the GitHub repo — it only works on your device.

⚠️ If you forget to revoke a key you've shared publicly, do so immediately at your API provider's dashboard.
