Overview
AI customer support that learns your business and answers customers 24/7 — live on your site, Slack and WhatsApp in 5 minutes, with human handoff when it matters.
Zendesk is the category-leading enterprise ticketing platform — deep, configurable and built for large multi-channel support operations. That power comes with weeks-to-months of setup, per-agent pricing, and AI features layered on as paid add-ons. If you want AI customer support that resolves repetitive questions without standing up a full enterprise help desk, a focused, flat-priced alternative gets you there far faster.
