Your monthly allowance
Your included allowance is designed to help you get started with Ari, Sidekick, and Plain’s other usage-based features. Your included credits reset each month on your billing anniversary. If your annual plan starts on April 15, your next allowance starts on May 15. Unused included credits expire when your allowance resets. They don’t roll over.What uses credits
Ari, External Agents, Sidekick, and AI workflows use credits. Ari and External Agents use a fixed amount for each action, and Sidekick and AI workflows use a variable amount that depends on the work. Nothing else in Plain uses credits.Fixed actions
A fixed action uses the same number of credits however complex the work is. Two products complete fixed actions: Ari and External Agents. Ari is Plain’s built-in, customer-facing agent. An External Agent is one you define, build, and run on Plain’s infrastructure: External Agents are how you bring your own agent to Plain. They’re available on the Frontier plan. An External Agent can use credits for a discussion, a thread assignment, or both, depending on how it’s involved.Variable actions
A variable action uses credits based on the request, the context, the tools, and the number of steps. A short task uses fewer credits. Work that needs more investigation, tools, context, or judgment uses more. Two products complete variable actions: Sidekick and AI workflows. Sidekick is Plain’s built-in internal agent. It helps your team investigate questions, gather context, and do work your customers don’t see. A Sidekick session starts when a user opens one or a workflow starts one, and it ends 24 hours after its last activity. AI workflows are workflows that use AI. Each run is billed once the workflow completes. These examples show what variable work costs:
The examples are a guide. Similar requests can use different amounts of credits.
