Problem

People delay dental care because they can't decode their own insurance — terminology, hidden costs, and coverage anxiety stand between them and treatment.

My contribution

End-to-end solo design: survey and interview research, IA, flows, UI system, AI-guidance concept, prototyping, and usability testing.

Outcome

A usability-tested final prototype — three participants across three initial sessions drove two major iterations reshaping two core screens; five participants then evaluated selected revised flows.

Constraints

Graduate thesis concept. Estimates and AI answers are educational guidance, not official insurance information; no launch data.

The Final Product Preview

Five screens.
No surprises.

Coverage, claims, booking, estimates, and answers — everything Emily needed from the front desk, before she leaves home. The rest of this page shows the evidence and decisions behind it.

The Cureon system — insurance benefit, claims, provider finder, cost estimator, and AI assistant staged on five iPhones
The core system — coverage, claims, provider finder, cost estimator, and the AI assistant.

Most Americans have dental insurance. Most can't explain it.

People with employer-provided plans skip appointments, avoid asking questions, and get surprised by bills — missing benefits they've already paid for.

Cureon answers the question behind all of it — “what will this actually cost me?” — with plain language, upfront estimates, and an AI assistant.

The Problem

People have coverage — they just can't confidently use it. Confusing terminology, unpredictable costs, and fragmented booking, billing, and benefits stand in the way.

01 — Research Interviews → Surveys → Insights

The data supported
what users were feeling.

Three survey findings set the agenda for everything that followed — each one pointing at understanding, not coverage, as the real gap.

Finding — 01

7of 7

survey respondents couldn't accurately explain their dental plan's coverage for common procedures.

Finding — 02

6of 7

survey respondents reported anxiety about unexpected costs when visiting the dentist.

Finding — 03

6of 7

survey respondents wanted mobile access to coverage details and cost estimates before appointments.

02 — Competitive Landscape 3 Products Audited

What existing apps
get wrong.

Three direct competitors, each solving a piece of the problem — none answering Emily's actual question.

Competitor · 01

Delta Dental

WeaknessPoor UI, no cost estimate tool, confusing navigation.

OpportunityTranslate raw plan data into plain language with upfront cost estimates.

Competitor · 02

Guardian

WeaknessNo AI chatbot, limited plain-language explanations.

OpportunityAdd AI-assisted guidance for the personal coverage questions a dashboard can't answer.

Competitor · 03

Zocdoc

WeaknessOverwhelming menus, no insurance transparency or cost estimates.

OpportunityPair provider booking with insurance transparency — cost per provider, before booking.

03 — Design Principles (04)

Four principles,
from evidence.

Research became a filter, not a report. Every screen that follows had to reduce a user's anxiety — or it was cut.

01

Clarity

Explain insurance in plain language anyone understands immediately. Every screen replaces terms like “annual maximum” with what they actually mean for the user.

Grounded in7 of 7 survey respondents couldn't explain their own coverage — terminology was the barrier, not the plan.

02

Transparency

Show benefit usage, coverage, and deductible progress at a glance — and put a number on every procedure before it happens.

Grounded in6 of 7 survey respondents reported cost anxiety — uncertainty, not price, is what delays care.

03

Smart support

An AI assistant answers coverage and cost questions in real time — questions no static FAQ can handle.

Grounded inUsers relied on office staff for answers their own tools couldn't give them.

04

Accessibility

A mobile-first flow usable without any prior insurance knowledge — because the critical moment is before the appointment, wherever the user happens to be.

Grounded in6 of 7 survey respondents wanted coverage details and estimates on mobile, before booking.

04 — Design Language Calm Under Stress

A visual system built
for clarity under stress.

Blue reinforces trust in a healthcare context; soft greens and warm neutrals keep the experience human. Alert coral is reserved exclusively for cost warnings — so it never loses its meaning.

Trust Blue · #1C538E
Mid Blue · #67A3DA
Sky Tint · #BFDCE5
Mint · #A8D5BA
Warm Ground · #F4EAE0
Alert Coral · #F88379

Blue earns the trust — coral is spent only on cost warnings.

Accessibility

WCAG-compliant contrast on all cost figures, 44-pt touch targets, and no color-only meaning — alerts always pair coral with an icon and label.

Typography

IBM Plex Sans carries dense insurance information; Poppins adds warmth to headings — legibility first, personality second.

Components

One shared set of coverage cards, progress bars, and status chips — plan information looks the same everywhere.

05 — Design Decisions (05)

Five features solve the
problem end-to-end.

Each feature traces back to a number from the research — and each decision below carries the reasoning it had to defend.

Coverage overview screen — plan benefits explained in plain language with coverage rings and the insurance card

Decision 01 · Coverage Overview

Plain language,
not plan language

A dashboard that explains coverage, deductible progress, and remaining benefits in words anyone understands — no more 40-page benefit documents.

WhyGrounded in the survey's coverage-confusion finding (Finding 01) — so every screen replaces “annual maximum” with what it means for the user.

Decision 02 · Cost Estimator

See what you're likely
to owe, before you book.

Enter a procedure and see the expected out-of-pocket cost upfront — with a code-level breakdown that shows exactly how the number is built.

Cost estimator screen — procedure categories with insurance summary and out-of-pocket estimate

The feature participants responded to most positively in usability testing — aimed squarely at the survey's cost-anxiety finding (Finding 02).

Provider finder screen — in-network dentists with ratings and specialties, compared side by side

Decision 03 · Provider Finder

The right dentist,
without the phone calls

Compare in-network dentists on availability, coverage, and cost side by side — then book directly in the app.

WhyChecking in-network coverage meant calling office after office — the finder replaces the call-around entirely.

Home dashboard — benefit usage, deductible progress, and upcoming appointment surfaced on the first screen Claims screen — claim details with code-level cost breakdown and insurance-paid summary

Decision 04 · Benefit Tracker

Never lose a benefit
to a missed deadline

Benefit usage and deductible progress live on the Home screen, with proactive reminders before benefits reset — and every claim itemized down to the procedure code.

WhyIn testing, users missed deductible info buried two levels deep. Surfacing it on Home turned passive plan data into timely action.

AI dental assistant chat — coverage question answered in plain language with quick-action chips

Decision 05 · AI Assistant

Answers, without
the front desk

An always-on assistant that answers coverage questions, explains billing, and guides users through claims — in the same plain language as the rest of the app.

WhyCoverage questions are personal — “is my crown covered?” can't be answered by a static FAQ. The assistant handles what users would otherwise ask office staff.

06 — Prototype 60-Second Walkthrough

The solution,
in sixty seconds.

A recording of the working prototype — home dashboard, coverage and claims, provider booking, cost estimate, and the AI assistant, in one continuous flow.

Δ 01

Deductible info → the Home screen

Deductible information sat two levels deep in the Benefits tab. The response: deductible progress moved to the Home dashboard, in plain language.

Δ 02

Cost ranges → code-level breakdowns

Testers asked “why is it $120–$310?” and didn't trust the number. The response: a code-level breakdown showing how the range is calculated.

I finally understood what my deductible actually meant — the progress bar made it click.

Jin Choi · Tester 01

I love that I can see the expected cost before visiting. It reduces my anxiety.

Jisoo Lee · Tester 02

The reset reminder on the home screen would've saved my cleaning benefit last year.

Risks & Constraints Honest Limits

What this concept
can — and can't — promise.

Cureon touches money, health, and AI guidance — its limits matter as much as its features.

Insurance-data accuracy

Plan details vary by employer and change yearly — a real deployment needs verified data sources.

Cost-estimate uncertainty

Estimates are educational ranges, not quotes — they should never read like a bill.

AI-response limits

AI explanations can be wrong or oversimplified — guidance is educational, not a replacement for the plan document.

Privacy & sensitive data

Consent, storage, and regulatory review sit outside this thesis's scope — prerequisites for a real product.

Accessibility

Full WCAG conformance and assistive-technology testing remain future work.

Trust calibration

Users may over-rely on AI answers — disclaimers at decision moments and paths to human help are essential.

09 — Reflection

Research prevented unnecessary features — every screen had to reduce user anxiety, or it was cut. That discipline produced the cost estimator, the feature participants responded to most positively in testing.

What I'd improve

Testing at high fidelity meant the deductible fix came two iterations late — wireframe-stage testing would have caught it sooner.

If it continued

Validate the AI assistant against real insurance data, and measure how cost transparency influences trust and appointment confidence.
