CogniAgent is an AI agent platform built for businesses that need their AI to do more than answer questions. Most platforms make you choose between a conversational tool that talks but can't act, and a workflow tool that acts but can't hold a dialogue. CogniAgent runs both on the same canvas: an agent can check a live system - your CRM, dispatch software, or order database - in the middle of a conversation and respond with the real answer, instead of promising to follow up later. Three capabilities, one platform: • Conversational AI agents - virtual employees that communicate: multi-turn dialogue across voice, SMS, chat, WhatsApp, email, Slack, Teams. They qualify leads, collect data, answer questions, and route requests through natural dialogue. • Autonomous AI agents run in the background, triggered by events, schedules, or thresholds, executing multi-step tasks across your connected tools without a person in the loop. • Cognitive AI agents combine both: they carry on a conversation and take action inside it - looking up an order, updating a record, or booking a slot - in real time. No handoffs, no separate automation layer. Getting started doesn't require a developer. Ready-to-deploy templates cover common use cases like lead qualification and follow-up, appointment booking, customer support and status updates, candidate screening, HR onboarding, and invoice or payment verification. The AI Concierge builds a working canvas from a plain-language description and can adjust existing agents on request - no canvas experience needed. CogniAgent connects natively to 2,700+ business tools, including major CRM, scheduling, ERP, and support platforms, so agents read and write live data instead of working from a static script.
