About this tool
Map family conditions and hereditary-history notes privately.
The Family Medical History Tree is a private note-keeper for hereditary health history: each record pairs a family member with the conditions and relation you want to remember, and the whole list is held in this browser's local storage until you export it as JSON. Add relatives one at a time, search across everything you have entered, delete individual entries, and import a JSON file back on another device. It is for anyone assembling the family-history answers a new GP, specialist or genetic counsellor asks for, without typing them into a cloud account first.
Open Family Medical History Tree on AltFTool — it loads instantly in your browser.
Type into the two boxes — Family member and Condition and relation — and press Add record; the entry is written to this browser's local storage under a key for this tool.
Use the Search records box to filter the Saved records list across both fields, and the Delete button on any card to remove one entry after confirming.
Export JSON downloads family-medical-history-tree.json, and Import JSON reads a JSON array back in, replacing every record currently saved here.
Records live in this browser's local storage, so a sensitive family history is not created as a row in someone else's database by default.
Export the full list as family-medical-history-tree.json and import it again later or on another machine, so the notes are yours to move and to back up.
The search box filters across both the family member and the condition text, which is what makes a list of thirty relatives usable at an appointment.
In your own browser's local storage, under a key specific to this tool, and nowhere else unless you export it. Clearing site data, using private browsing, or switching browser or device will lose it, so export the JSON if the record matters.
Name or relationship, the condition, and the age at which it was diagnosed — age at onset is the detail clinicians ask about most, because a condition appearing unusually early carries different weight than the same condition in later life. Note which side of the family each person is on as well.
Most clinical family-history forms ask about three generations: you and your siblings and children, then parents, aunts and uncles, then grandparents. First-degree relatives — parents, siblings and children — carry the most weight, so start there and add further out as you learn more.
No. It only organises what you write down; it does not calculate risk, interpret patterns or offer a diagnosis. Bring the exported notes to a GP or a genetic counsellor, who can judge whether the pattern warrants screening or testing.
