Verified reality
The listing didn't change.
Your understanding did.
Verification score
0
Verified · 8 facts confirmed · 1 discrepancy
Availability is worth 30. Price accuracy 20. The amenities you actually asked for, 20. A confirmed fact always outscores an assumed one.
Contradictions between the listing and the call are deducted on top. A score is never rounded up into a higher band.

No dashboard to learn. You describe what you want, and Propster does the searching, the calling and the checking.
This readout mirrors the pipeline the product actually runs. In the application it is driven by live provider events from the call in progress.
The voice layer
CALL-E
Propster builds the objective and validates the answers. CALL-E holds the conversation — it dials the number, speaks to the person who picks up, and returns the facts as structured data.
