Question 1

Is Sophie Well free?

Accepted Answer

Yes. Sophie Well is free, open source under the MIT license, and ad-free. The full source is on GitHub.

Question 2

Is Sophie Well safe to use with patient data?

Accepted Answer

Every calculation runs locally in your browser. Nothing you type is sent to any server. The site enforces a strict Content Security Policy and ships no analytics, telemetry, or third-party CDN. You alone control whether information stays on your device.

Question 3

Does Sophie Well work offline?

Accepted Answer

Yes, after first load. A service worker caches the static bundle so every tool keeps working without an internet connection.

Question 4

Does Sophie Well replace my EHR calculator?

Accepted Answer

No. Sophie Well is a deterministic reference aid. Your EHR remains the system of record for documentation, orders, and billing. Use Sophie Well as a check, not a replacement.

Question 5

Where does Sophie Well's data come from?

Accepted Answer

Public datasets (CMS, FDA, OIG, AHA, CDC, ATSDR, NIOSH, DOT) plus published clinical literature. Each tool shows its primary citation and, where applicable, a dataset Source label with the fetched-on date in the References region under the result.

Question 6

Can I use Sophie Well for billing decisions?

Accepted Answer

Sophie Well is a reference and educational tool. Use it to look up codes, decode statements, and learn the workflow; payer-specific rules, contracted rates, and certified billing review govern actual claims.

Question 7

Is Sophie Well HIPAA compliant?

Accepted Answer

HIPAA applies to covered entities and their business associates. Sophie Well is neither: it is a static website that stores no data and transmits nothing you type. Whether you may use it with PHI depends on your organization's policies, not on a vendor BAA.

Question 8

Does Sophie Well use AI?

Accepted Answer

No. Every tool is a pure deterministic function or a lookup against a bundled public dataset. No models, no inference, no LLM calls, in the browser or anywhere else.

Question 9

How current are the codes (ICD-10, HCPCS, CPT)?

Accepted Answer

ICD-10-CM follows the annual fiscal-year update (October). HCPCS is refreshed quarterly. CPT descriptors are AMA-owned and are not bundled; structural CPT rows come from the CMS Medicare Physician Fee Schedule. Each tool surfaces its dataset fetched-on date.

Question 10

Can I trust Sophie Well's clinical scores?

Accepted Answer

Every clinical formula is implemented from the primary citation shown in its References region, and is covered by unit tests against the published example values. Sophie Well is a check on the math, not a substitute for clinical judgment.

Question 11

How do I report a bug or wrong answer?

Accepted Answer

Open an issue at github.com/clay-good/sophiewell.com/issues. Include the tile, the inputs, the expected output, and the citation you compared against. Bug fixes ship as small PRs against main.

Question 12

Who built Sophie Well?

Accepted Answer

Clay Good (claygood.com) builds and maintains Sophie Well. It is a personal project shipped as a public utility under the MIT license.
