Lab results explained in plain words, data kept private

People understand their lab results in minutes, and their health data never goes to third parties

Manual work

How we got there

  1. Issue found

    People google each value on their lab report, one by one, in fear — and health data is the most sensitive category there is.

  2. How we checked

    Verified end to end with real reports, including the trend across reports of the same person; every value cites its page and row on the source PDF.

  3. Root cause

    A search engine cannot read the interval printed on that specific report, and a model left alone will guess numbers. Trust needs the number to come from the paper, not from the model.

  4. What we fixed

    A deterministic parser reads every value and interval from the PDF; the model only writes the words; explicit health-data consent before anything; one-click export and erasure; one cookie, no third parties. It never diagnoses.

  5. Measured Delivered

    Live · zero analytics, zero third-party requests

    Window: productionCaveat: Usage is not measured — by design. No analytics on health data.

What was built

The system, in short.

Upload the PDF; a deterministic parser reads every value and the interval printed on that report; the model only writes the words; every value cites its page and row; explicit health-data consent before anything; one-click export and erasure; one cookie, no third parties. Never diagnoses.
