ONE AGENT · EVERYTHING IT DOES

Not just chat. Watch it work.

One agent handles chat themes, lead capture, human handover, omnichannel, FAQ, help center, Jira and Zendesk. Follow along — each capability, live.

UNDER THE HOOD · WHAT MAKES IT AN OPERATOR
AUTO-LEARNING
Drop a PDF or URL. It learns the rest.

Scans, chunks and indexes your docs and pages — then answers from them with citations. No tagging, no training data.

PERSONALITY
Give your agent a character.

Name it, set its tone, and decide when it escalates or asks for feedback — all from an editable prompt.

NO-CODE WORKFLOWS
Drag, drop, automate.

Build multi-step flows — conditions, forms, messages, human handoff — visually. No engineers required.

MCP TOOLS
Take action, not just talk.

Connect MCP tools so it can look up orders, issue refunds, create tickets and call your own APIs — mid-conversation.

INTEGRATES WITH
Slack Shopify Jira Webhooks REST API + MCP
LEADS, NOT JUST TICKETS

Every conversation is pipeline.

The same agent that answers questions quietly qualifies the people asking them. It helps first, then — at the right moment — asks a few smart questions and captures the lead. No forms, no bounce.

  • Answer-first capture — asks after it’s been useful, not before
  • Qualifies on intent, then routes to sales, Slack or your CRM
  • Every visitor, lead & customer in one deduplicated profile
