What is Dot?

Dot is ChartKey's AI companion. What it does, what it never does, and how it uses your records.

Dot is the companion at the center of ChartKey. You can talk with Dot by voice or by typing — ask a question about your records, mention how you've been feeling, or just think out loud. Dot listens, remembers what belongs in your chart, and keeps an eye on the follow-ups your own records mention.

Why "Dot"?

Your health story is made of small moments — a visit, a lab result, a note about how you were feeling. Each one lands on your timeline as its own dot. On their own they're easy to lose track of; together they make a picture. Dot is named for those moments, because connecting them is the job: listening for the new ones, remembering where they belong, and helping you see the picture they add up to. (Dot is also the small round mark you'll see in the app — tap it to talk.)

And if you've been using ChartKey for a while: Dot is the same companion that used to be called Keeper. The name changed; what it does — and the rules it works under — did not.

What Dot is — and isn't

Dot is an AI — not a doctor or nurse, and not a substitute for clinical care. That line appears on Dot's screen because it is the honest description, not fine print. Dot never diagnoses, never treats, and never tells you a clinician is wrong. For medical decisions, talk to a licensed clinician.

What Dot actually does

• Listens and remembers. When you tell Dot something that belongs in your health story — a symptom, a change, a question for your next visit — it is written to your chart the same careful way a connected hospital record is, and you can always see what was written.
• Reads your records, so you don't have to. Dot can look things up in your own chart when you ask — recent results, medication lists, visit notes.
• Notices follow-ups. When a clinician's note mentions something due later — a recheck, a screening, a referral — Dot can surface it as a suggestion. You decide what to accept; nothing is added to your plan without you.

Where Dot's answers come from

Dot's answers about your health come from your records — never from guessing. If it can't find something in your chart, it says so.

Your controls

You choose Dot's voice, or turn voice off entirely and type instead. Every conversation is yours: what Dot writes to your chart is visible in your timeline, and your data rights — export and delete — cover it like everything else. See Your data rights.
