From clinical to clear.

Clarixos is exploring how clinician-authored correspondence can be reorganised and explained for the person receiving it — without changing what it says.

See a letter read againWhat we are evaluating

Ix: TTE — LVEF 48%, mild MR, no RWMA.
Bloods: eGFR 62, NT-proBNP 418.
Plan: bisoprolol 2.5mg OD. FU 3/12.

An ultrasound measured your heart's pumping fraction at 48%. A follow-up is planned in three months, with repeat blood tests.

The communication problem

Written for one reader. Received by another.

Clinical correspondence is written first as clinical communication. It can be precise, complete and entirely correct — and still be unreadable to the person it describes.

SOBIn the letter

Shortness of breath — on exertion, not at rest

11 abbreviations
1 paragraph

6 terms, explained

Choose a term to explain

Left ventricular ejection fraction

The share of blood your heart's main pumping chamber pushes out with each beat, measured on an ultrasound scan of the heart. Your letter records this as 48%.

The second reading

Choose a term. Watch it open.

The letter stays exactly as written. Clarixos adds a reading of it — and every explanation stays tied to the passage it came from.

These examples are fictional. Not real patient information.

Clarixos explains the terms used in your letter. It does not assess your results, and it does not give advice — questions about what this means for you are for your clinical team.

Six letters demonstrate connected reading. Choose an example to follow its source, explanation and reader view.

The product experience

A reader, not a dashboard.

Structure down the left, the letter in the middle, the reading beside it. Technology shows up as the quality of the reading — not as chrome.

Cardiology clinic letter · 04 Sept

Why you were seen

You were referred because you have been getting breathless when you exert yourself. At your appointment on 4 September you described this happening with more effort than usual, and .

LVEF 48%. Why you were seen selected.

Behaviours

Reading, navigating structure, selecting terminology, switching original / reading / both, and following provenance.

Absent by design

Risk scores, confidence percentages, traffic lights, charts, chat.

Status

An aspirational product experience shown while Clarixos is developing and evaluating its approach — not a live service.
