Buying, sharing, selling prompts – what prompt marketplaces offer today (and why this is relevant for UX)

When we as UX professionals think about generative AI, we almost always talk about tools: ChatGPT, Midjourney, DALL·E, Claude, Sora. And when we use these tools, it's often about finding the right prompt. The magic phrase that turns the language model into a designer, copywriter or strategist. But those who don't want to delve into the depths of prompt craftsmanship every time now have a new infrastructure to fall back on: prompt marketplaces.

These marketplaces work a bit like Etsy, GitHub or Themeforest – offering ready-made prompts to buy, test or share. The best platforms are not just a collection of templates, but places for exchange, specialisation and (sometimes) making money. And they show how prompting can become a professionalised UX skill.

In this article, you will find a selection of the most exciting and diverse international marketplaces – from the ChatGPT community to NFT-based shops to fully integrated video prompt exchanges. We look at:

• What the platform is suitable for (text, image, audio, multimodal?)

• How it is structured (free, affordable, cryptic?)

• What community is behind it (open, curated, exclusive?)
  

And, of course, what it all means for our work as UX designers.

1. PromptBase: The classic with a marketplace, job board and API connection

PromptBase is one of the oldest and largest marketplaces – launched in 2022, when prompting was still considered a niche for nerds. Today, it offers prompts for ChatGPT, DALL·E, Midjourney, Stable Diffusion & Co.

• Focus: Text and image prompts for a wide range of applications: UX writing, marketing, design, coding

• Model: Sale of individually optimised prompts (approx. £1–3 per prompt)

• Special feature: With a job board for prompt engineers and training for beginners
  

UX relevance? Anyone who creates prototypes, user research or text modules with AI support will find well-tested starting points here – and can also monetise their own prompts.

2. PromptHero: Image worlds, communities and lots of inspiration

PromptHero is less of a marketplace and more of a free library. Millions of image prompts (Midjourney, DALL·E, etc.) are displayed here – always with the corresponding prompt. The platform thrives on an active community and is completely free of charge.

• Focus: Visual prompts, ideal for UX/UI design, branding and creative processes

• Model: Open library with community rankings and portfolio function

• Special feature: Courses, prompt learning, forums and job board for visual engineers
  

UX relevance? Ideal for quick inspiration in design projects – and for teams that want to systematically collect image prompts internally.

3. FlowGPT: The Reddit for ChatGPT prompts

FlowGPT focuses on prompts for ChatGPT – no images, no NFTs, just dialogue and text prompts. But it has an impressive community: users rate, discuss and improve prompts together. There are competitions, hackathons and rankings.

• Focus: ChatGPT dialogues and roles, from product ideas to customer service

• Model: Completely free, community-driven

• Special feature: Test function directly in the browser and structured category systems

UX relevance? Very high – anyone who models personas, assistants or interview guides in ChatGPT, for example, will find practical examples and variations here.

4. PromptSea: Prompts as NFTs 

Sounds crazy? It is. PromptSea converts prompts into NFTs. So you buy a prompt with real proof of ownership (e.g. on the Polygon chain). Prompt details are encrypted until purchase. After that, you can use, resell or collect it.

• Focus: Creative text and image prompts, sold as unique digital items

• Model: Crypto marketplace, payment in coin, no preview

• Special feature: Blockchain-based ownership and collector's logic
  

UX relevance? Niche, but exciting: PromptSea shows how prompts can become creative assets – with clear authorship, limitation and market value.

5. LaPrompt: The all-rounder for text, image, video, audio and 3D

LaPrompt is one of the few platforms that supports multimodal prompts. It offers image and text prompts, as well as video, audio and even 3D content. The prompts are sold in ‘shops’, including sample outputs.

• Focus: Multimodal, creative AI use (storytelling, music, motion design)

• Model: Sales platform with verification process and shop function

• Special feature: Broad media portfolio and own creator stores
  

UX relevance? Very high for creative UX fields: sound UX, motion prototyping, scenic storytelling or immersive UIs. LaPrompt shows how far prompting can go in interface design.

6. AIPRM: Prompts directly in the ChatGPT interface

AIPRM is a browser extension for Chrome that integrates prompts directly into the ChatGPT UI. Ideal for SEO, marketing, sales or tech prompts. Prompts can be filtered, saved and used in a team. The tool works on a freemium basis.

• Focus: Productivity prompts for professionals (SEO, UX copy, structural aids)

• Model: Free basic version + paid pro version with additional features

• Special feature: Embedded in the workflow, no separate website
  

UX relevance? Particularly exciting for repetitive tasks in content creation or as an internal prompt catalogue within a team.

7. ChatX: Quality promise through bounties

ChatX pursues an exciting model: prompts are free, but authors receive a fixed fee (approx. £25) for each approved prompt. This creates a small but curated library.

• Focus: Text and image prompts for typical everyday applications

• Model: Free for users, fixed fees for authors

• Special feature: Curated prompt catalogue + order service for special prompts
  

UX relevance? More exciting for beginners. But also an interesting impulse: Could UX prompts be curated in a similar way?

Conclusion: Prompting becomes a platform

The marketplaces presented here show how multifaceted the topic of prompting is currently developing:

• As a library for inspiration (PromptHero, FlowGPT)

• As a marketplace for paid prompts (PromptBase, LaPrompt)

• As a system component for UI integration (AIPRM)

• As a testing ground for ownership and tokenisation (PromptSea)
  

For us as a UX community, this presents a twofold opportunity: on the one hand, the platforms help us find, test and use better prompts. On the other hand, they provide insight into how UX mechanics such as trust, ownership, testability and contextualisation can be applied to prompts themselves.

Perhaps we will soon need our own prompt libraries in our design systems. Or prompt onboarding for new colleagues. Or a prompt debugging tool.

Whatever comes next, the platforms out there are a good start. And an exciting reflection of what we as UX professionals can help shape ourselves.
