Plain pricing

Plain does not publish machine-readable pricing.

No structured plans recorded. Plain may quote on request, which means an agent cannot work out the cost of a call before making it.

Can an agent buy this on its own?

A price is only half the question. The other half is whether software can get from landing on the site to making a paid call without a person, which is what the AgentReady measures under adopt.

Against that, account creation needs a person; a sales call gates access; the signup flow assumes a human at a browser; credentials must be minted by hand in a dashboard. Each of those is a point where an unattended run stops and waits for a human.

That works out to 20/100 on adopt, against 46/100 overall.

What you are paying for

Plain is AI support infrastructure that enables B2B teams to build anything – no-code or all-code. It is a support platform where customer conversations arrive from email, Slack, Microsoft Teams, chat, Discord, or your own product, and become threads in a single queue that your team and your AI agents both work from. It is built API-first with a GraphQL API.
