Platform
Everything you need
to deploy voice agents
The Stellar platform is a no-code stack for building, deploying, and improving AI voice agents. It includes the agent builder, the industry knowledge base, self-learning, multi-agent pipelines, built-in compliance, and 15+ integrations with the calendars, CRMs, and ops tools you already use. One subscription, no engineers required.
Agent Builder
Build your agent in minutes
Configure voice, persona, script, and handoff logic across eight tabs. Every change is versioned. No code, no engineering escalation.
- 8 configurable tabs per agent
- Voice, persona, script, KB, connections
- Change history + rollback
Knowledge Base
Your industry's knowledge plus your own business content
Stellar ships 16 preloaded industry packs (HVAC, dental, real estate, legal, auto repair, veterinary, and more) and lets you layer your own pricing, team policies, service area, and FAQs on top. Your agent answers from your content, not a generic model trained on the open web.
- 16 industry packs preloaded out of the box
- Upload PDFs, docs, and URLs from your site
- Sub-200ms retrieval per call
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
Run a qualifier agent first, wait an hour, send a follow-up email, then have the booking agent dial the lead back. Context carries across every step, so the booking agent already knows the caller is a qualified $15K, two-month-timeline opportunity before it picks up the phone.
- Voice, email, SMS, wait, and webhook steps
- Cross-step context propagation
- Retries, timeouts, and exit conditions
Integrations
Connects to the tools you already use
Security
Compliance built into the platform, not patched on later
Stellar handles FCC one-to-one consent capture, TCPA-safe calling windows by region, AI identity disclosure on every call, and recording disclosure. Calls are encrypted with AES-256 in transit and at rest, account data is isolated at the database level so cross-tenant access is architecturally impossible, and SOC 2 readiness is verified.
