CRM
The call next to the deal in your CRM
The breakdown attaches to the contact or the deal, so a customer's history gathers in one place.
Notifications
Notifications in Slack and Telegram
A weak call, a sharp drop in score, or a new objection can be pushed to a work channel.
If yours is not on the list
An open REST API and webhooks
A POST with a link to the audio and the rep's identifier is enough. From there the call travels the normal pipeline.

Content-Type: application/json
X-Webhook-Secret: <your secret>

"status": "PENDING",
"queued_at": "2026-09-01T10:12:04Z"

// then the pipeline stages:
// DOWNLOADING_AUDIO → UPLOADING_TO_S3
// → TRANSCRIBING → ANALYZING

What it runs on
What this runs on
