Where Susan's health information comes from

Susan is an AI assistant, not a clinician, and she does not do her own research. When she talks about health or safety, she is drawing on guidance published by the organisations below, and she is only permitted to link to them. Every page linked here is theirs, not ours — follow any link to read the source in full.

This page is a reading list, not medical advice. Hey Susan does not diagnose or treat anything, and nothing here replaces your doctor, midwife, or other licensed provider. If something worries you, contact them — and in an emergency call 911 or your local emergency number. Read the full medical disclaimer.

“Verified on” below means our automated link checker confirmed that specific page was reachable — not archived, not moved, not deleted — as of that date. It is not a claim about anything on the page beyond that.

How Susan uses them

Susan is only permitted to link to the organisations above. If the AI model behind her produces any other address, it is removed automatically before the message reaches you, and a link from this list is offered instead — so a made-up reference can never be presented to you as a source. She will not always cite a source in every reply, which is exactly why this page exists: it is the standing answer to “where is this coming from?”

Susan's replies are generated by an AI service — see our Privacy Policy for who processes your data and what is shared.
