Inclusion rule. A tool is listed when its own page states the limit this question turns on. Order. Tools in alphabetical order.

Extra credits decide whether a series can finish on the plan it started on. Where they are on sale, a heavy episode is a top-up; where they are not, it is an upgrade.

Several pages tie them to a plan: LTX Studio's top-ups come with its higher plans, Kapwing's with its team plan, and Morphic's packs only after upgrading.
