PromptBase

PromptBase is a marketplace where prompts themselves are the item on sale: individual prompts for image, text and video models, listed with previews of what they produce and priced per prompt. The listing this entry is built from describes it as the shelf you go to when someone else has already solved a prompt you need, as opposed to a skill you develop yourself.

That description could not be re-checked against the live site, so it should be treated as what this entry has always claimed rather than as something confirmed now. If it holds, it suits people who want a known-good starting point for an image or writing task and are content to pay once, and it suits sellers who have a prompt that produces something repeatable. It would suit less well anyone whose work depends on a prompt continuing to behave: prompts are tied to particular models and versions, and a model update can change or retire what a listing demonstrated, which is a risk the marketplace cannot remove.

Not verified: promptbase.com could not be loaded at all this time. Every request — the home page, a marketplace category and even the robots file — came back as HTTP 403 from the site's bot-protection interstitial, so no page content was read and nothing about the current catalogue, pricing, model coverage, seller terms or whether the marketplace is still operating was confirmed here. The description in the first two paragraphs is therefore unverified for this entry, and the claims the previous version made about output previews and seller earnings were not re-checked either.
