What a year costs.
Billed yearly. Squibler's yearly prices are its monthly equivalents times twelve; billed month to month, Plus is $29.99 and Pro $89.99.
Each company's credit is its own unit, so credits don't compare. Squibler Pro's credits are unlimited. If you run out on Feldar, your writing stays available; only the AI pauses.
