Meridian Assist: AI support desk inside the product

An in-app support assistant that answers from approved help docs, escalates cleanly to humans, and keeps coaches in control.

Challenge

Problem space

B2B customers needed fast answers without waiting for business hours, without inventing policy.

Business impact

Long first-response queues and agent time spent on repetitive FAQs.

Solution direction

Ground answers in help content only, cite sources, and escalate when confidence is low.

Solution

We embedded a retrieval-grounded assistant in the product with citation links, escalation to ticket queues, and admin controls over which docs the model can use.

What we shipped

  • In-app support chat
  • Cited help articles
  • Escalate to human
  • Admin doc allow-list
