How Stellar compares
Honest, side-by-side comparisons against other AI voice agent platforms. We show where we win and where competitors shine.
Switching to Stellar
Do Stellar agents actually sound human?
Yes — that's our core differentiator. Stellar uses the latest neural voice synthesis with natural pacing, tone variation, and the ability to handle interruptions gracefully. Most callers genuinely can't tell they're speaking with AI.
Can I port my existing phone numbers?
Yes. Stellar supports number porting for all plans. Your callers keep the same number while your human-sounding AI agent takes over.
Is there a free trial?
Yes — every account starts with a 14-day free trial of Growth (3 agents, 200 minutes, every integration). No credit card required. Build, run real calls, and only commit once you're sure it works for your business.
How long does migration take?
Most teams are live within 30 minutes. There's no data migration. You start fresh with Stellar's templates and customize the voice and knowledge from there.
Do I need developers to set up Stellar?
No. Stellar's no-code builder handles everything from voice personality to calendar integration. If you want API access, it's available on Pro and Scale plans.
Can I use Stellar alongside my current tool?
Yes. Many teams run Stellar in parallel during evaluation. Compare how callers respond to the human-sounding voice versus your current setup, then decide.
