Sample and live modes

Prepared examples do not call Claude. When you explicitly run live mode, your reusable prompt and question are sent through our server to Anthropic for processing. The website labels sample output separately from live output.

Data handling

The demo processes inputs and responses in memory while handling your request. It has no database for submissions and does not intentionally log prompts, source code or access tokens. Infrastructure providers may process request metadata and operational logs under their policies. Exported reports are saved by your browser to your device.

Receipts include token counts, timings and request identifiers. Cost calculations are estimates, not billing statements.

Service providers

Live AI processing uses Anthropic. Cloudflare hosts the website and handles requests. This service does not restrict data processing to the United States. See Anthropic’s privacy policy and Cloudflare’s privacy policy.

Browser storage and contact

MetaBench stores a theme preference in localStorage and a preference cookie shared across its website and app subdomains. No analytics service is configured in this preview. Contact links open your email application. Access requests and other emails are retained as needed to respond and manage preview access; request deletion by email.

Your choices

Use sample mode without submitting live data. Do not send API keys, credentials, personal records or proprietary source without permission. To ask about access, correction or deletion of information you sent us, email us.
