| Description | Sierra is a conversational AI platform that lets companies build and deploy autonomous AI agents for customer experience—handling support, driving revenue, and taking backend actions across chat, SMS, WhatsApp, email, voice, and ChatGPT. Aimed at mid-market and enterprise CX and operations teams, it stands out for its outcome-based pricing (you pay for resolved outcomes, not seats) and Ghostwriter, an agent-building agent that turns SOPs, transcripts, and plain-English goals into production-ready multilingual agents. | SignalZen is an AI-powered customer support and live chat platform for small and medium businesses. Its AI answers from your website, files and help center and hands conversations to human agents. The platform includes a customisable chat widget, an AI copilot that drafts replies for agents, a public knowledge base, two-way translation and conversation summaries. Agents can reply from Slack, Microsoft Teams or Google Chat. Plans are monthly: Starter is $29 (up to 2 operators), Basic $49 (up to 5), Pro $99 and Business $199 (both unlimited operators), with a 30-day free trial and no permanent free plan. |
