Sierra
Sierra builds and runs customer-facing conversational agents across chat, voice, email and messaging by ingesting SOPs, transcripts or audio, generating agents (Ghostwriter), and running automated tests plus observability (Insights). Inputs are documents and audio; outputs are deployed agents, test results, and performance reports.
The linked official pages describe an outcome-based pricing approach but do not list plan prices or specific dollar amounts for any tier.Is Sierra right for you?
Good for
- Customer‑experience teams needing a multichannel conversational platform with automated agent generation and observability for production agents.
- Multichannel deployment across chat, SMS, WhatsApp, email, voice, and ChatGPT.
- Ghostwriter builds agents from SOPs, transcripts or audio and auto-runs simulations with fixes when tests fail.
Keep in mind
- Public site describes outcome-based pricing but does not provide plan prices or billing details on the linked official pages.
- Confirm pricing structure and billing commitments with sales before purchase, since linked official pages describe outcome‑based pricing but show no numeric plan prices.
