- On Pro the same 10,000 credits cost 189 USD a month on monthly billing against 340 USD as a pay-as-you-go pack, so the subscription is cheaper per credit at volume.
- Credits are shared across all websites and projects under one account, with unlimited websites and no per-site fees.
- Pay-as-you-go credits never expire, and unused Pro and Scale credits carry forward every month.
- The yearly steps are shown as a per-month figure, so 4 USD a month on yearly billing is 48 USD charged once for the year.
A Monthly and Yearly toggle is shown, with yearly labelled -20%. Pro credit volumes are chosen on a slider. Pay-as-you-go packs have no subscription and all features except the web snippet. Scale starts at 200 USD a month, billed monthly or annually.

AltTextLab limitations
- Credits are the unit and one credit equals one image, so cost scales with image count: from 0.05 USD a credit at the entry Pro tier.
- The web snippet that adds alt text to every image automatically is available on subscription plans only, not on pay-as-you-go.
- Scale starts at 200 USD a month with custom credits, and the credit volume at that price is not published.
- The credits roll over statement is listed on Pro and Scale but not on Free, so whether the 25 monthly free credits carry forward is not stated.
