		Related Products kama.ai The Responsible AI-Agent for organizations where the answer HAS TO BE RIGHT. kama.ai answers from knowledge your team approves, not from what a model guesses. Every response is accurate, consistent, and traceable to its source. Governed by design. How it works: kama.ai is built on a Knowledge Graph AI. Your team curates Trusted Collections of approved information and documents, and the AI Agent answers from them exclusively. Best of all you get consistent answers to the same questions - every time. Governed Generative AI helps with phrasing and coverage within limits you set. Then Intelligent Automation lets the Deterministic AI agent complete multi-step tasks. No hallucinations allowed, where real-world consequences are at stake. This AI doesn’t just answer questions. A Human in the Loop approves key, high frequency questions - to make sure everything is brand-safe. Why it's different: Most AI chatbots generate first and add guardrails afterward. kama.ai works the other way around: Deterministic AI first to guide and orchestrate. Then generative AI helps only where you allow it. This lowers the risk of AI adoption for teams that can't afford a wrong answer about a permit, a policy, the way to fix an expensive machine on the line, a procedure, or their brand. Built for: manufacturers, municipalities, government, colleges and universities, professional services, non-profits, museums, and Indigenous services organizations. Purpose-built to be transparent, accountable, and culturally aware. Get the right information to the right people, at the right time. If it's got to be right, it's got to be kama.ai. 9 Ratings Visit Website Zendesk Zendesk is an AI-powered service solution that’s easy to set up, use, and scale.
