Frequently Asked Questions (FAQs)

What does $0.01 per conversation mean for text, email, or chat?

You’re charged $0.01 for each unique user interaction within a 24-hour window — regardless of the number of messages exchanged. This applies to chat, email, or SMS conversations, whether live or tested in the Playground. No hidden fees for message count, complexity, or channels.

What does $0.01 per minute mean for voice?

For voice interactions, you’re billed $0.01 per minute of active AI-agent conversation — across both live and Playground calls. Billing starts when the agent begins speaking and ends when the call is complete. No extra charges for concurrent calls or agent complexity.

Are there any hidden fees?

None. No charges for uploading a knowledge base. No fees for concurrency, flows, intents, or usage limits. SigmaMind’s pricing is simple: $0.01 per conversation or per voice minute — whether you’re testing in Playground or going live.

Is there a charge for concurrent users or active calls?

No concurrency fees. Whether 1 or 100 users are talking to your agent at once, the pricing stays the same — $0.01 per conversation or per minute. You scale. We don’t penalize.

Do I need a credit card to start?

No. Build for free — add billing only when you're ready to go live or test.

Can I bill per client?

Yes — use separate workspaces with individual usage tracking and billing.
