B2B-first AI helpdesk. BYO-model (Claude, GPT-4, whatever), open APIs, native Linear and Slack sync. Built for SaaS support teams.
Overview
Plain is the modern B2B SaaS support platform. Unlike Zendesk or Intercom (built for consumer-scale ticket volume), Plain is designed for the support patterns of B2B SaaS: long-running threads, multi-stakeholder conversations, deep Linear and Slack integration. The AI layer is BYO-model — point it at Claude, GPT-4, or your own model — and the API is genuinely first-class. Best for technical SaaS companies who want to engineer their support, not just configure a vendor product.
