Evidence before automation

A payer answer you can actually defend.

Kol uses CALL-E to chase claim status, remembers the phone-tree route, and blocks every result that cannot prove what was asked, who answered, what they said, and how the call got there.

Public demo uses fictional claims. No EHR writes. Live calling is PIN- and destination-gated.

Not another voice bot

The call is not the record. The evidence is.

A correctly shaped answer can still be wrong. Kol turns each field into a claim that must survive independent checks before it moves downstream.

Hear the question

The transcript must show the exact claim-specific question. A plausible answer to an unasked question is held.

Ground every field

Status, amount, full date, denial code, and department each need payer-side evidence.

Prove the route

Model-reported keys must agree with a fixture log, decoded DTMF audio, or independent provider event.

Route Atlas

Remember the path. Distrust the shortcut.

Kol replays a reviewed IVR route only while the live prompts still match. Drift quarantines the map and forces exploration next time.

Versioned payer routes

Every correction creates a new, inspectable route version.

Fail-closed drift

A remapped key never silently teaches the atlas.

Measured time, honest scope

Exploration and replay timings stay separate; no invented savings.

Replay the fictional evidence lab, inspect route drift, then place one controlled test call when you are ready.
