Tools you can use before you ever talk to me
Three free, private tools that run entirely in your browser. Nothing you type into any of them is ever sent anywhere, stored anywhere but on your own device, or seen by anyone, including me.
The tools
Signal Cards
Twelve fillable versions of the one-page Signal Card that ends each symptom chapter of Worth Investigating. Pick the signal that fits, fill in what you've noticed in your own words, and print or save it to bring to an appointment.
Fill in a Signal Card →Two-Week Symptom Tracker
The day-by-day record from Chapter 7, "Keeping the Record": one line a day, for two weeks, following the book's exact format. Usually the step before filling in a Signal Card.
Start the tracker →GLP-1 Reflection Tool
Ten questions to organize your own thinking before you sit down with a prescriber about a GLP-1 medication. Not a medical test, and it can't tell you what to do — it can stop you walking into that appointment with nothing but a feeling.
Take the reflection tool →Why these are safe to use honestly
None of these tools score, total, or rank what you enter, and none of them output a diagnosis, a likelihood, or a recommendation. Each one is built the same way: everything runs in your browser, nothing is transmitted to a server, and the code for each is linked from its own page if you'd rather verify that yourself than take my word for it.
Every tool here is education, not medical advice, diagnosis, or treatment. How I research and write
