Callers.ai
Callers.ai is an Agentic Customer Experience Platform for high-volume B2C teams. It deploys AI agents across voice, chat, email, SMS, and WhatsApp, carrying customer context from one interaction to the next. Teams use Callers for inbound support and after-hours coverage, alongside outbound lead qualification, booking confirmations, onboarding, re-engagement, and retention. Agents draw on interaction history and connected business systems to respond and take action, with context passed to human teams when needed. The platform connects with existing CRM, help desk, calendar, and knowledge systems rather than replacing them. Business teams define goals, workflows, and guardrails, then use reporting to improve performance. Callers supports enterprise setup, integration, and ongoing optimization, so organizations can start with one workflow and expand based on results. -

AgentVoice
AgentVoice
AgentVoice is a platform for building AI‑powered voice agents that can make and answer phone calls and take meaningful actions, like booking meetings, sending texts, and updating CRMs, without requiring a developer. Each call flows through speech recognition to transcribe what’s said, a large language model to determine what to say and do, and an AI‑generated voice to respond naturally. Our agents don’t just respond, they execute tasks during or after the call using real data, memory, and tool access. You can create no‑code workflows that update CRMs, schedule meetings, send follow‑ups, screen leads, handle voicemails, or filter spam calls, all in the same call. Setup is fast, you can create and launch a working agent in less than 30 minutes, using no code: define your agent, choose a voice, connect your tools via 200+ native integrations, low‑code options, or a robust API and webhooks, then upload or generate a script.Starting Price: $50 per month
