What is Plain?
Plain is a customer support platform aimed at technical B2B companies, with an API-first design and AI built in. It brings email, Slack, Discord, chat and forms into one queue and is used by developer-focused companies that want to script their support workflows.
Everything in Plain can be automated through its GraphQL API and webhooks, so engineering teams can connect it to their own product data. Its AI agent can answer questions, and teams can also bring their own agent and plug it in through MCP and APIs.
Pricing is published per user with a seven-day free trial that does not need a card, and higher plans add more channels and automation. Customers include developer-tool companies that run support through Slack and Discord communities.
