Lumen
An AI image studio that turns a text prompt into styled image sets, billed by credit packs.
Built the studio around a text-to-image pipeline — nine starter styles, one to four outputs per run, aspect ratios and seed locking — plus a credit wallet, a library with lightbox and history, and Google and X sign-in.
What needed solving.

What we shipped.
An editorial brand identity for an AI image studio — an aperture mark paired with a "punctuation of light" wordmark, built into a flexible system for a product whose output is light itself.
The hard part.
Generation can fail or run long, but users pay per image — so naively charging on request would bill people for nothing. We made credits a reserve-then-settle wallet: hold on submit, charge only on a delivered result, auto-refund on failure. More state to track, but billing stays honest.
What it shipped to.
A pay-per-generation studio with no subscription — users buy credits, run prompts across styles, and only spend on results they actually get.
