A few important limits

Open availability is not a licence to republish full lyrics. An AI explanation is not automatically a reviewed finding. Similarity does not establish influence. Catalog browsing does not require an account. If you create an account, we store your email (via our identity provider) and hashed connection keys. We record first-party funnel events (sign-in started, account ready, key created or revoked) and minimized tool traces (tool name, time, outcome, optional user id). We do not store poem text, chat prompts, or raw API keys in those traces. Traces expire after about 30 days; funnel events after about 90 days. We do not use third-party advertising pixels. Connected AI clients send tool arguments; do not include secrets. Operator contact: the Heydjan site operator via the community form.

A small, growing pilot. Not every question will have a match.
