Modshelf
A creator-first marketplace where power users publish and sell 'AI assistant mods' — bundled system prompts, slash-command packs, response style guides, and visual skins — that anyone can one-click install.
writers, coaches, teachers, and creators who want to monetize their AI workflow expertise
- Pack builder for bundling prompts, examples, and themes into a single installable mod
- Curated 'for you' feed based on the user's profession, tone preference, and use case
- Royalty split when your mod gets installed by paying subscribers
- Built-in A/B testing so authors see which prompts actually improve user outcomes
The 'fork it' essay proves developers will hack their AI tools — there's no equivalent playground for the much larger creator economy to share AI customizations.
AI prompt marketplace category is real and growing (KBV Research projects ~$7.92B by 2032; FlowGPT raised $10M pre-A; PromptBase and AIPRM have live commerce), but the specific 'mods/bundles one-click install' framing for non-technical creators is unproven and largely overlaps with existing prompt listings.Top AI Prompt Marketplaces 2025: Best Platforms, Trends, Revenue ↗AI Prompt Marketplace Market Size, Share | CAGR of 25.3% ↗
Market is already crowded with PromptBase, PromptHero, FlowGPT, AIPRM, ChatX, PromptSea, plus OpenAI's GPT Store with native distribution — leaving limited differentiation for a new entrant unless 'mod' bundling plus one-click install is uniquely executed.Top AI Prompt Marketplaces 2025: Best Platforms, Trends, Revenue ↗PromptBase Alternatives for Buying AI Prompts in 2025 ↗
Willingness to pay exists (PromptBase charges 20% commission, AIPRM charges $37–$150 for bundles), but creator earnings are thin ('couple hundred to low four figures/month') and GPT Store payouts are ~$0.03/conversation — most buyers still prefer free prompts, weakening premium-mod pricing power.Top AI Prompt Marketplaces 2025: Best Platforms, Trends, Revenue ↗The Agent Creator Economy 2026: What Developers Actually Earn ↗
Category may be ephemeral: model providers (OpenAI, Anthropic, Microsoft) can natively ship mod stores and slash-command systems, squeezing third-party marketplaces the way app stores compressed mobile web — and prompts have no IP moat, so value is easily replicated.The Agent Creator Economy 2026: What Developers Actually Earn ↗
A marketplace with payments is standard web work, but 'one-click install' across ChatGPT/Claude/Cursor requires either browser-extension plumbing (AIPRM precedent) or platform partnerships — there's no universal mod API, so cross-AI install is meaningfully hard.Top AI Prompt Marketplaces 2025: Best Platforms, Trends, Revenue ↗
