Answer-first descriptionWhat AI engines quote

Plain is an AI-powered support infrastructure platform built for B2B teams that need flexibility to handle customer conversations across Slack, Microsoft Teams, email, Discord, and in-product channels. It combines a unified workspace with AI agents, workflow automation, and real-time insights, letting teams build their support motion with or without code. Pricing is not publicly listed; a free trial and demo are available.

B2B support teams typically juggle fragmented tools and channels, losing context and getting constrained by opinionated software. Plain solves this by consolidating all channels into one workspace, orchestrating AI agents alongside human teammates, automating triage and routing, and surfacing themes, churn risks, and upsell signals from support data — without forcing a fixed workflow on the team.

→Unifies Slack, Teams, email, Discord, and in-product chat into a single support workspace

→Orchestrates multiple AI agents (including built-in agent Ari) alongside human teammates for triage, investigation, and resolution

→Automates routing, labeling, and cross-system actions via workflows, with a full API for custom extensions
