Prompt Vault

Prompt Vault is an AI-powered content strategy system for creators, coaches, freelancers, and solopreneurs who are tired of AI-generated content that doesn't sound like them.

Here's how it works: you get a single file. You attach it to any AI chat, ChatGPT, Claude, Gemini, DeepSeek, or any other platform. The file asks you 5 questions about your brand, audience, and voice. From that point on, the AI produces content that actually sounds like you.

No commands. No prompt engineering. 7 niche templates included.

Built in public, $0 budget.
