Logo Diffusion vs Logomark AI
The split is subscription studio versus pay-per-logo. Logo Diffusion is a full logo studio (text-to-logo, vectorizer, mockups) on credits: free with 24 credits refilled weekly (watermarked, no commercial license), paid from $24/month with a commercial license on paid plans. Logomark AI generates logo options free in the browser and charges per download through one-time payments/credit packs, with SVG export and a built-in editor. Subscribing only makes sense on Logo Diffusion if you design logos regularly; for a single logo, pay-per-download is cheaper. There is no measured quality winner in this review.

Use the same input
Generate a logo for a fictional coffee brand on both, then try to export a vector (SVG) file and see what the free tier gives you.
What a successful result must preserve
The comparison must report what file format and license each free tier provides, since that decides whether the logo is usable.
