Kasane
A mother leaning on the kitchen counter with her morning coffee, her husband and son laughing at the table behind her. A girl holding out a spoonful of oatmeal to her laughing mother at a sunny breakfast table. A father on the sofa with his son, wrapped in a blanket and grinning over a piece of toast. A mother playing soccer in the backyard with her two kids under a big oak tree. A father and his son making tacos together at a terrazzo kitchen counter. A mother reading a picture book in bed with her two young kids.

Type or say it the way you’d text a friend: “my usual breakfast and a 30 min row, tummy’s good.” Kasane files the meal, the row, and how you feel at the right times, in your words. Sleep and workouts from your watch or ring fill in on their own, through Apple Health.

Marcus’s Journal this morning: his brief, last night’s sleep from Apple Health with his overnight vitals typical, and the morning’s routines.

Keep the details for the next visit.

Each of your kids gets a journal of their own. Write in it the way you write in yours: “102°F at 3 am, gave her children’s Tylenol, back asleep by 3:40.” When the pediatrician asks when it started, it’s there with the date and time.

Share a child with your co-parent, and you both write in her journal from your own phones. Whoever was up with the 3 am fever writes it down, and it’s there for the other one at breakfast.

Jordan writing in Mia’s journal: Mia woke up at 3:05 with a fever of 102, gave her children’s Tylenol, back asleep by 3:40. Kasane files it at 3:05 am and asks how much Tylenol she gave.
Mia’s journal: woke at 3:05 am with a fever of 102, children’s Tylenol, back asleep by 3:40, then this morning’s check-in and tonight’s bedtime routine.

Helping a parent with complex care?

Keep their medications, blood pressure readings, and visit notes in a journal of their own, with a list for the next appointment. Sharing it with the siblings who help is coming in a later update.

Robert’s journal, kept by his daughter: morning pills and the home blood pressure check marked done, and a note reading BP 132/80, pulse 60 on the home cuff.

Find what helps you feel better.

Turn a question into one small change, starting from a habit already in your day when one fits. Kasane keeps track while you try it, then looks back with you on what changed. Or pick any habit and tap Help me with this: Kasane coaches it, asks each day how it’s going, and looks back with you after a couple of weeks.

  1. Get curious about what’s going on.

    Marcus has been dragging by 2 pm for months, and his August blood work came back normal. He asks why in his own words, and Kasane guides the investigation: what his journal already shows, and what might be behind it.

    Marcus’s hunch: maybe afternoon coffee is cutting into his sleep.

    Marcus’s question, Tired all the time: last coffee by noon on day 4 of 14, with the look-back set for Tuesday, November 3.

  2. Try one thing.

    For two weeks, his last coffee is by noon, and he checks it off in the Journal. Each afternoon, Kasane asks “Tired all the time today?” and he taps None, A little, or A lot.

    Marcus’s Journal on day 3 of the try: a 2:55 pm check-in, tired a lot, a note about a headache since lunch, and last coffee by noon checked off.

  3. Look back, then decide.

    Headaches the first three days, then about the same: tired on 12 of 14 afternoons, 10 of 12 before. He gives it two more weeks, past the caffeine withdrawal, and brings his notes to his follow-up.

Ask about anyone in the family.

Each person has a page with their health profile, labs, and documents. Ask about them right there, and the answer cites their own labs, documents, and events.

Bring in a lab report.

Add a lab PDF or a document to their page. It’s read on your iPhone, identifiers like names and record numbers are stripped before any AI model sees the text, and each value waits for you to review it.

Let Ask help.

Ask can file a visit summary you share into their documents, offer to log a symptom you mention, and update a birthday once you say yes.

Ready for the next visit.

Keep each person’s care team in one place, with a list of what to bring up at the next appointment.

Cheer each other on.

Connect with your partner by invite code. You each see the one thing the other is working on, the days it got done, and any ask for help, and you can send a cheer. You choose what else they see, from meals and notes to your medications and labs, and you can turn any of it off.

Your data
is yours.

Your journal lives on your iPhone and in your own iCloud, and you decide where it goes next.

  • Read on your phone.

    Lab reports and documents are read on your iPhone, and identifiers like names and record numbers are stripped before any AI model sees the text.

  • Straight to the model.

    Kasane works with Claude, by Anthropic, once you agree to it. Each request goes from your phone straight to Anthropic, and Apple’s models stay inside Apple.

  • Take it with you. Planned

    Export everything in one zip, work on it with any AI agent, and bring the changes back after you review each one.
