What our research says

PromptBase

Worth a look if you want a shortcut to a specific visual style and would rather not reverse-engineer it, or if you have a genuinely repeatable prompt to monetize. As a buyer you are paying for text whose output shifts every time the underlying model updates, so treat prompts as perishable rather than as assets.

Pros

  • Unit prices are low, typically single-digit dollars per prompt
  • 0% commission on your own referral-link sales versus 20% on marketplace traffic
  • Covers a broad model spread including image, text and video systems
  • Stripe payouts rather than money trapped in an internal wallet

Cons

  • Prompt quality is largely unvetted and results drift as models update
  • Preview images are seller-supplied and not independently reproduced
  • No API, so nothing here slots into an automated pipeline
  • $19/month Select only pays off at genuinely high prompt volume

PromptsGenii

The pitch is that picking a style from a visual list beats remembering prompt vocabulary, and the image-to-prompt step is the genuinely useful part - reverse-engineering a reference you already like. A one-time $49 licence with no recurring fee is unusual and worth something. The risk is the flip side of lifetime pricing: no recurring revenue means no guarantee anyone keeps it current.

Pros

  • Converts an uploaded image into a starting text prompt
  • More than fifteen filter categories - artists, architecture, styles - to layer onto a prompt
  • Refines prompts through OpenAI or Gemini, so you are not tied to one model's phrasing
  • One-time licence with no recurring charge, and seat packs for teams
  • Public roadmap and changelog show what is being worked on

Cons

  • Chrome and Edge only - no Safari, Firefox or standalone app
  • Lifetime pricing means future updates depend entirely on the vendor's goodwill
  • MagicMakersLab publishes no country, address or team
  • $49 up front with no free tier visible to test the filters first
