AGENTIC Infrastructure

Support infrastructure built for AI agents

Support infrastructure built for AI agents

Your agents need to read threads, send messages, escalate to humans, and close issues. Plain gives them the APIs to do all of it.

Bring your own model

Connect any model trained on your docs, customer history, and code.

Handles the common cases, escalates the rest

Agents respond to threads directly and hand off to a human when they're out of their depth.

The infrastructure is already there

You write the agent logic, Plain handles the rest – workflows, thread state, routing and more.

HOW IT WORKS

Every action is an API call away

Scoped permissions per agent

Provision a key for each agent with exactly the permissions it needs — read threads, create sessions, resolve approvals, manage tool connections. Nothing more.

Agents slot into your existing workflows

The same rules you use to route threads to human agents work for AI agents. Route by channel, customer tier, label, time of day - or even AI prompt.

Ground every answer in knowledge

One API call gives you back ranked passages from your help center articles and indexed docs. No separate vector store to build or maintain.
