Self-Learning

Agents that evolve with every call

After each conversation, Stellar analyzes what worked. High-confidence improvements auto-apply. Lower-confidence ones queue for your review before they ship.

  • AI-powered post-call analysis
  • Auto-apply threshold (confidence ≥ 0.85)
  • Human approval for grey-zone changes

Pipelines

Chain agents into multi-step workflows

Lead qualifier → wait 1 hour → follow-up email → book with appointment agent. Context carries across steps so the booking agent already knows the caller is a qualified $15K/2-month lead.

  • Voice + email + wait + webhook steps
  • Cross-step context propagation
  • Retries, timeouts, and exit conditions

Automations

If this outcome, then that action

Every completed call can fan out into CRM tags, follow-up emails, Slack notifications, webhook fires, or call retries. Built-in if/then engine, no Zapier required for the common cases.

  • Triggers on call outcome, tag, or score
  • Actions: tag, email, webhook, Slack, retry
  • Plan-gated: Pro = 25 rules, Scale = unlimited
