- +True omnichannel: chat, email, voice, and messaging with multi-language support and safety guardrails

Ultimate.ai
- +Strong multilingual automation (80+ languages) via purpose-built language-agnostic models
- +Hybrid scripted, generative, and human-handoff flows with no-code dialogue and integration builders
- +Now backed by Zendesk's resolution platform and ecosystem
- -No longer purchasable standalone; locked into Zendesk's ecosystem and repackaging roadmap
- -Usage and per-resolution pricing inside Zendesk can get expensive and unpredictable at scale
