Overview

Certainly builds autonomous AI agents for customer experience, designed to “reason, act, and resolve” conversations end-to-end without human escalation, deployed across web, email, SMS, social media, and voice channels.

Model flexibility sets it apart from single-provider chatbot builders – it supports Anthropic’s Claude family, Google’s Gemini, OpenAI’s GPT models, and 200+ additional models via OpenRouter (DeepSeek, Mistral, Llama, Qwen), with automatic failover and cost optimization. Integration with 100+ business tools (Shopify, Zendesk, Salesforce) connects agents directly to existing workflows, with go-live possible in as little as 14 days.

Certainly targets CX leaders and enterprises seeking to reduce support ticket volume and increase revenue through conversational AI, backed by enterprise security (GDPR, SOC 2, 99.9% uptime SLA). Pricing isn’t shown on the homepage; see the dedicated pricing page.
