How credits work

Luna direct AI: text 1 credit · image 2 credits · PDF 5 credits. Sol reviewed visual AI: image 12 credits · PDF 18 credits. Sol first reads the worksheet for you to check before it solves; confirming those readings adds no extra charge. Uploads are limited to 4 MB, PDFs to 2 pages. Additional input limits may apply to unusually complex files. Failed AI solves return eligible reserved credits under their original expiry and payment restrictions. Verified accounts, available credits and service spending limits are required for AI requests.

When to use Luna or Sol

Use Luna when the source is clear and you want lower-cost direct help. Use Sol when a worksheet photo, handwriting, graph label or measured diagram is important enough that you want to inspect the AI’s source reading before it calculates. The extra Sol credits pay for that two-stage visual workflow; they do not guarantee a correct answer.
