About Plain
Plain is a customer support platform built for B2B companies. It pulls customer conversations from Slack, Microsoft Teams, Discord, email, live chat, a help center and in-app forms into a single workspace, so support teams can handle requests from business customers without switching tools. The company describes it as support infrastructure that can be configured with no code or extended with code through its API.

- AI Triage and Routing: Letting Ari and workflows classify, route and investigate incoming issues before a human responds.
- Engineering Escalations: Linking conversations to issue trackers such as Linear or Jira and alerting teams through PagerDuty.
- Churn and Upsell Monitoring: Using Insights summaries and daily digests to spot at-risk accounts.
