Seven basics, done right.

The interaction patterns every AI product needs, each set where a mistake costs something, with the one decision that makes it work.

Why one day

Table stakes, judged on the details.

Many AI products already ship some version of these seven patterns. What separates them is a handful of decisions: what happens after you stop, which claims get a source, and who made which change. Each section below names the problem, the decision, and how it's built. All screen content is example data.

01 / Control

Stop is not the end.

Problem

Hitting Stop can leave the answer frozen or broken, so users wait out a wrong answer or start over.

Decision

Stopping starts steering. Everything written so far is kept, and only the part you point at is redone.

How it works

Stop aborts the stream, and resuming sends the kept text back with your new instruction.

Which plan is cheaper if I see a specialist monthly?

For monthly specialist visits, Plan B likely costs less over the year. Its specialist copay is lower, and you'd hit the deductible on Plan A before savings kick in.

On premiums, Plan A is cheaper per paycheck, but that gap closes after

Hi Dana,

02 / Verification

Show me where that came from.

Problem

About one in four AI search citations don't support their sentence, and people tend to trust a citation without checking it.

Decision

Cite each sentence, not the whole answer, open the exact passage in place, and say plainly when there is no source.

How it works

The model returns each sentence with a source id and the quoted span, which is matched against the document.

Main · health plan Q&A

Do I need pre-approval for an MRI?

Yes, outpatient MRIs need prior authorization1, and your doctor's office usually submits it. Approval typically takes a few business days.

Diagnostic tests and lab work are covered at 80% after deductible.

Advanced imaging (MRI, CT, PET) requires prior authorization when performed in an outpatient setting.

Emergency imaging does not require approval.

03 / Uncertainty

Confidence without numbers.

Problem

People over-trust wrong answers, and plain hedging like "I'm not sure" reduces that better than long explanations.

Evidence: FAccT 2024, CHI 2025
Decision

Mark confidence on each claim by where it came from, and give every weak claim a way to check.

How it works

Each claim comes back tagged as in your documents, one source, or inference.

04 / Agency

Change by change.

Problem

Ask the AI to fix one paragraph and it quietly changes others too.

Decision

One change is the unit of consent, each with a one-line reason, and the AI never adds facts you didn't give it.

How it works

The model returns a list of changes (from, to, reason), shown as a diff with accept and reject on each.

05 / Reversibility

Every change can be undone.

Problem

Undoing one AI edit can wipe far more than that edit, even in tools built for it.

Decision

History is grouped by intent, shows whether you or the AI made each change, and undoes one change without losing the later ones.

How it works

Each change is stored with the instruction that caused it, so undo removes just that change.

06 / Cold start

Starters that read the room.

Problem

A blank box makes people guess what the AI can do before they can ask anything.

Decision

Three suggestions at most, built from what's on screen, each saying why it's there.

How it works

Screen data goes to the model, which returns three questions, each with its reason.

07 / Transparency

Reasoning on request.

Problem

Showing the full reasoning raises trust without improving accuracy, and in one model, full traces made accuracy worse.

Decision

Collapsed by default, opened automatically when the stakes are high, and shown as assumptions you can fix.

How it works

The model returns its assumptions as editable fields, and changing one reruns the answer.

Main · plan comparison
