AI-first help desk that resolves tickets, not just sorts them
Kay classifies, prioritises and routes incoming tickets, enriches them with customer context, and cuts the manual sorting that eats agent time.
The AI drafts accurate replies or asks follow-up questions, automatically handling repetitive cases and shortening average handle time.
Kay learns from human resolutions, expands its intent coverage and compounds deflection performance over time.
Email, live chat, social and voice land in one shared queue with full customer history, orders and data attached to every ticket.

AI help desk automation that resolves IT requests inside Slack and email
Risotto answers routine questions from Notion, Confluence, Drive, Slack and third-party docs, keeps answers current as documents change, and turns threads into knowledge articles.
Escalated tickets are investigated against the employee's credentials, tool logs and chat history, then a draft solution is prepared for one-click agent approval.
Employees request access in Slack or email; Risotto handles approvals, time-based rules and dynamic policies, then provisions users through your IAM/IGA tools with a full audit trail.
Route questions to IT, HR, Finance, Legal, Engineering or Sales Ops by intent rather than keyword, with RBAC controls and category auto-tagging.
