Free Plan
The Free plan is the no-cost OpenCharts tier — full access to flowcharts, whiteboards, notes, presentations, AI extraction, and Theo with a monthly AI credit allotment.
In depth
Free includes the entire feature surface (no feature gates) and ships with a base monthly AI credit pool that resets on the calendar. When you need more, upgrade or buy a credit pack.

Starter Plan
Starter is the entry paid plan — bigger AI credit allotment, more storage, and higher export limits for individuals and small teams.
Unlimited Plan
Unlimited is the heavy-usage plan — the largest AI credit pool, full media engines, expanded storage, and access to advanced engines like Theo Reason and Consensus.
Teams Plan
Teams is the multi-seat plan — shared AI credit pool, centralized billing, organization-level storage, and team admin controls.
AI Credits
AI Credits are the unit OpenCharts uses to meter Theo usage — every chat reply, image, video, or autonomous skill run consumes a credit amount based on the engine and tools involved.
