We only index prompts from permissive, licensed sources. Each entry shows its full source list in the sidebar. Below are the source families we use and their license requirements.
CC-BY sources require attribution. Where a prompt originates from a CC-BY source, we credit the source name and its license on the entry page. If you re-use such a prompt, keep that attribution.
Non-commercial (CC-BY-NC), no-derivatives (CC-BY-ND) and unlicensed sources are rejected outright. Sources we treat with extra caution (e.g. aggregate libraries needing per-entry verification) are labeled on the entry page.
