What Is Plain?
Plain is a customer support platform built for B2B software teams, with an AI agent called Ari and an internal assistant called Sidekick. Plain's own pricing page, read directly, shows Foundation at $45 per user per month billed annually, with a Save 20% label next to a $55 monthly figure, Horizon at $99 per user per month billed annually, and Frontier as custom. Member seats are up to 5 on Foundation with a minimum of 3, up to 10 on Horizon with custom above that, and viewer seats are unlimited. Foundation includes 1,000 credits a month, Horizon 2,500 and Frontier custom. Top-ups are $10 for 1,000 credits, $20 for 2,000, $50 for 5,000 and $100 for 10,000. AI is metered in credits: Ari costs 100 credits per resolution, Sidekick 15 to 300-plus depending on effort, and Connected Agent 15 credits per assignment plus 15 per discussion. A 7-day free trial needs no card and there is a 50% startup discount.
Third-party reviews quote $35 for Foundation and $299 for Horizon with 2,000 and 15,000 credits, which conflict with the page, and a structured-data snippet on the page still contains the $35 text, so the older pricing may linger. One source says Ari is included on every plan and does not use credits, which conflicts with the page's 100 credits per resolution, so verify. Funding: about $21 million raised including a $15 million Series A led by Battery Ventures in February 2025. At 100 credits per resolution, 1,000 included credits cover only about 10 Ari resolutions, so heavy automation means buying credits.
Plain suits B2B SaaS teams that want a modern, API-first support tool. Compare Pylon, Hiver and Document360. Browse the Customer Support tools directory for more.
