Question 1

What is Stellar?

Accepted Answer

Stellar is a no-code platform for creating, deploying, and managing AI voice agents that handle phone calls for your business. Stellar agents qualify leads, confirm event attendance, and book appointments using natural-sounding conversations that callers often mistake for real people.

Question 2

How does Stellar work?

Accepted Answer

You choose a template (lead qualification, event confirmation, or appointment booking), customize the voice and personality, upload your knowledge base, and connect your integrations like Google Calendar. Stellar handles the rest. When a lead submits a form or a call comes in, Stellar's AI agent calls or answers with a human-sounding voice, follows your script, and takes the right action.

Question 3

What types of businesses use Stellar?

Accepted Answer

Stellar is built for SMBs and agencies across healthcare, real estate, professional services, and event management. Any business that needs to answer inbound calls, follow up with leads, or confirm appointments can use Stellar. Agencies also use Stellar to deploy white-label AI voice agents across their client base.

Question 4

Do I need technical skills to use Stellar?

Accepted Answer

No. Stellar is a no-code platform. You build and configure agents through a visual builder with templates, drag-and-drop knowledge base uploads, and one-click integrations. If you want API access for custom workflows, it is available on Pro and Scale plans.

Question 5

What makes Stellar different from other AI voice platforms?

Accepted Answer

Three things: voice quality, speed to deploy, and simplicity. Stellar uses neural voice synthesis that produces natural pacing, tone variation, and interruption handling. Most competitors require developer setup or produce robotic-sounding calls. Stellar gets you live in under 30 minutes with no code, and callers genuinely cannot tell they are speaking with AI.

Question 6

Do Stellar agents actually sound human?

Accepted Answer

Yes. Stellar uses the latest neural voice synthesis to produce natural-sounding conversations with realistic pacing, tone variation, and the ability to handle interruptions gracefully. Most callers genuinely do not realize they are speaking with AI.

Question 7

How natural does Stellar's voice sound?

Accepted Answer

Stellar uses native speech-to-speech voice technology, so there's no awkward delay between listening and responding. The AI handles understanding and voice generation in a single pass instead of a slow STT-then-LLM-then-TTS pipeline. Most callers don't realize they're talking to AI in the first 30 seconds.

Question 8

Can Stellar handle interruptions and natural conversation?

Accepted Answer

Yes. Stellar agents handle interruptions, pauses, and back-and-forth conversation naturally. The speech-to-speech model processes audio directly, so it responds to tone and pacing the way a human would, not just words.

Question 9

Can I customize the voice and personality?

Accepted Answer

Yes. You choose from multiple natural-sounding voices and configure the agent's personality, tone, and speaking style. You can make the agent formal or casual, fast or measured, and match your brand's communication style.

Question 10

What is AI lead qualification?

Accepted Answer

AI lead qualification uses a voice agent to call new leads, ask qualifying questions (budget, timeline, decision authority), score their fit, and route qualified leads to your sales team. Stellar calls every new lead within 60 seconds of form submission, so you reach prospects while they are still engaged.

Question 11

What is AI event confirmation?

Accepted Answer

AI event confirmation uses voice agents to call attendees before an event, confirm their attendance, handle reschedules, and update your headcount in real time. Stellar supports multi-touch campaigns with up to 3 follow-up attempts, reducing no-shows by up to 38%.

Question 12

What is AI appointment booking?

Accepted Answer

AI appointment booking means an AI voice agent answers inbound calls 24/7, checks your calendar availability in real time via Google Calendar, and books appointments on the spot. No hold music, no missed calls, no phone tag.

Question 13

Can Stellar handle inbound and outbound calls?

Accepted Answer

Yes. Appointment booking agents handle inbound calls. Lead qualification and event confirmation agents make outbound calls. Each agent type is optimized for its call direction.

Question 14

What happens after a call ends?

Accepted Answer

After every call, Stellar runs post-call analysis using AI. It generates a call summary, extracts key data points, scores the lead (for qualification calls), and triggers any automation rules you have set up, such as tagging contacts, sending follow-up emails, or notifying your team on Slack.

Question 15

How much does Stellar cost?

Accepted Answer

Stellar starts with a free plan (1 agent, 30 minutes/month). Paid plans: Growth at $149/month with 200 minutes included, Pro at $399/month with 750 minutes included, and Scale at $899/month with 3,000 minutes included. Overage rates range from $0.11 to $0.18 per minute depending on plan. No hidden fees or contracts.

Question 16

How does billing work?

Accepted Answer

You pay a flat monthly base fee that includes a generous allocation of minutes. If you go over your included minutes, additional minutes are billed at your plan's overage rate. No surprises, no hidden fees.

Question 17

What counts as a minute?

Accepted Answer

Minutes are measured from when the AI agent connects to when the call ends. Ringing, hold time, and voicemail detection are not counted.

Question 18

Is there a free plan?

Accepted Answer

Yes. Every account starts with a free plan that includes 1 agent and 30 minutes of call time per month. No credit card required. Hear for yourself how natural it sounds, then upgrade when you are ready.

Question 19

How long does it take to set up Stellar?

Accepted Answer

Most teams are live within 30 minutes. Choose a template, customize your agent's voice and personality, upload your knowledge base, connect your calendar, and you are ready to take calls.

Question 20

What integrations does Stellar support?

Accepted Answer

Stellar integrates with Google Calendar (real-time availability and booking), Google Sheets, HubSpot, GoHighLevel, Slack, Typeform, Jotform, Eventbrite, Zoom Webinars, WebinarJam, and custom webhooks. All plans include Google Calendar and webhook triggers. Pro and Scale add additional integrations.

Question 21

What is the knowledge base?

Accepted Answer

The knowledge base is where you upload documents, FAQs, and information your AI agent should know. When a caller asks a question, the agent searches your knowledge base and answers using your actual content. This ensures accurate, on-brand responses grounded in your real documentation.

Question 22

Can I use my existing phone number?

Accepted Answer

Yes. Stellar supports number porting for all plans. Your callers keep the same number while your AI agent takes over.

Question 23

Is Stellar TCPA compliant?

Accepted Answer

Yes. Stellar includes built-in TCPA compliance features including consent tracking, do-not-call list management, business hours enforcement, and call recording disclosures. All outbound calls respect consent requirements and calling windows.

Question 24

Is Stellar GDPR compliant?

Accepted Answer

Yes. Stellar supports GDPR data retention policies, data export, and deletion requests. Call recordings and transcripts can be automatically purged based on configurable retention periods.

Question 25

How is my data protected?

Accepted Answer

All data is stored in Supabase with row-level security. Every database query is filtered by account, making cross-tenant data access architecturally impossible. OAuth tokens are encrypted with AES-256-GCM. All connections use HTTPS.

Question 26

Are calls recorded?

Accepted Answer

Call recordings are available on paid plans. Recordings are stored securely and can be reviewed in the calls dashboard. You can configure automatic retention periods to comply with your data policies.
