VERDICT: MAYBEBERG SCORE 68/100

Modular Prompt Library for AI Coding

A community-curated marketplace of reusable, plug-and-play AI coding prompts for standard app features like authentication, payments, and notifications.

01 THE IDEA

The idea is a shared repository or marketplace of modular prompts that developers can drop into Cursor or other AI coding tools to instantly scaffold standard features — like user authentication (OAuth), Stripe payments, email notifications, etc. — without having to re-prompt from scratch every time. Think 'npm for AI prompts,' where the community contributes, rates, and maintains prompt templates for common functionality.

The value is clear: every new app needs the same 10-15 boilerplate features, and each developer currently wastes hours reprompting and debugging. A curated, tested library of prompts with known-good outputs dramatically speeds up the early build phase. Monetization could come from a freemium model, prompt marketplace commissions, or a SaaS subscription for teams.

03 THE VERDICT

This is a high-timing opportunity: the AI coding wave is cresting, no dominant platform owns this niche yet, and the pain point is universally felt by every non-engineer builder. Network effects from community contributions create a defensible moat over time. The main risk is that Cursor or a competitor bundles this natively, but even then, an independent community asset has value.
