Typed demo live now · evidence engine underneath
The report changed. The answer shouldn't be a guess.
Talk to your records. Voice Memory checks corrections, conflicting values and missing approvals, then shows exactly what the evidence supports.
Illustrative synthetic records only. Not a diagnostic or clinically validated product.
Amended 15 October 2026: ferritin result corrected from 5 to 50 (transcription error).
Corrected value “Your ferritin is 50 ng/mL. The 12 October result was corrected from 5 to 50, and I'm using the corrected value.”
The 80-second film
People read their records before anyone explains them.
Records change: a preliminary result gets amended, a lab switches units, a proposal gets revised. A chatbot that reads the newest line, or the wrong patient's, sounds confident either way.
Ask the records. Out loud or typed.
The live evidence engine, on fictional documents. Every answer below is computed now, with the line it rests on.
Voice calling is temporarily off; typed asking is fully live.
Pick a question, type or dictate your own.
Answers come from the documents only, checked against the exact line they cite.
Bolna hears it. The record decides it.
Speech in, a checked sentence out, and the source on screen while you listen. (Voice calling is paused for now; typed asking above is fully live.)
-
01
Bolna takes the call
Speech recognition, turn-taking and the voice you hear run on Bolna (currently paused). Your question arrives as text.
-
02
Voice Memory resolves it
“Forty two thousand” becomes $42,000. “It” becomes the fee you just asked about.
-
03
The engine checks the source
Finds the original passage, then its status: amended, preliminary, proposed, approved, which patient, which unit.
-
04
One sentence, one line
A short answer the record supports goes back to Bolna to speak. The cited line opens on screen.

Memory graph
Every value remembers where it came from, and what replaced it.
Reports, values and the exact sentences behind them, joined by corrects, supersedes and not comparable edges. The same graph the engine answers from.
