Nexus platform overview

Nexus is Yellow.ai's flagship platform for building and running AI agents, at nexus.yellow.ai. It takes an agent through its whole lifecycle - build it, give it knowledge and data, take it live across every channel, handle real customer conversations, and measure and improve it - all in one place.

Nexus Tip

New to Nexus? The Nexus AI Layer can scaffold your whole bot from a one-line description - agents, triggers, and starter tools - so you start from something working instead of a blank canvas.

What's in Nexus

Nexus is organised into products, mirroring the studio's left rail:

• Harness - build AI agents: Configuration, agents, tools, widgets, voice, and testing.
• Atlas - the knowledge your agents answer from.
• Fabric - the customer data (profiles and segments) your agents read and write.
• Inbox - live customer service: human agents, tickets, and queues alongside your AI.
• Analytics - conversation insights, dashboards, and quality trends.
• Engage - outbound and inbound campaigns across channels.
• Channels & Deploy - take your agent live on web, WhatsApp, voice, and more.
• Integrations - connect CRMs, ITSM, payments, live chat, and other systems.

Two things run across all of it: the Nexus AI Layer - the in-app copilot that builds and edits by asking - and the AI Trust Centre - evaluation and safety for everything you ship.
