Building an anonymous AI photo editor without letting one visitor take the GPU

Turner AI, a browser-based AI photo editor, allows anonymous users to edit images without an account while preventing GPU abuse through a fairness system. The tool separates convenience from authority, ensuring failed requests do not consume user allowances. The product is free, requires no account, and does not watermark downloads.

I’m building Turner AI, a browser-based AI photo editor: https://turner.art https://turner.art The visible workflow is simple: upload a photo, write what should change, and download the result. The harder engineering problem is fairness. I wanted the first edit to work without an account. But image editing is not a zero-cost request, and anonymous traffic means a small number of visitors can consume a disproportionate amount of GPU time. The design we are moving toward separates convenience from authority: That last point matters. A failed upload, a failed human check, or a rejected request should not silently spend someone’s allowance. The product is free to try, requires no account, and successful downloads do not carry a Turner watermark. For developers who have shipped anonymous compute-heavy tools: would you add signup earlier, or keep the first-use flow open and enforce fairness behind the scenes?
