About
Support platform for B2B and developer teams with Slack, email and in-app channels, Linear and Jira integrations and AI agents.
Plain is a customer support platform for teams that ship software. It handles Slack, email, in-app and Microsoft Teams conversations, with a help center, knowledge base, SLAs, business hours and escalation paths. Workflows, auto-labelling, urgency detection and thread summaries reduce manual triage.
AI features include the Sidekick agent, a customer agent and suggested responses. Integrations cover Linear, Shortcut, Jira, GitHub, HubSpot, Attio and Salesforce, with importers for Intercom, Freshdesk, Zendesk and Help Scout, plus an API, webhooks and MCP. Plans are Foundation, Horizon and Frontier, and a 7 day free trial needs no credit card.
