What is a Prompt Receipt?
A Prompt Receipt is a verified, encrypted AI prompt that you can buy, sell, and trust. Every receipt is hashed before listing, encrypted at rest, and only decrypted in your browser after you purchase it. Think of it as a digital certificate of authenticity for an AI instruction set.
The Trust Model
SHA-256 Hash
Every prompt is hashed before listing. The hash is public — you can verify the content you receive matches exactly what was listed, byte for byte.
AES-256-GCM Encryption
Prompt content is encrypted at rest. The decryption key is never exposed until a verified purchase is recorded — no leaks, no previews.
Immutable Audit Trail
Each purchase is recorded with a payment reference, buyer ID, and timestamp. Sale counts and ratings are public, giving you a clear signal of what actually works.
Seller Accountability
Sellers are authenticated users. Their username is attached to every receipt. Bad prompts get bad ratings — the marketplace self-corrects over time.
How It Works
Seller uploads a prompt
Paste or upload any prompt, agent config, or instruction file. Promptora automatically generates a summary, tags, complexity rating, and model compatibility — no manual metadata required.
Content is hashed & encrypted
Before the receipt goes live, the raw content is SHA-256 hashed and encrypted with AES-256-GCM. Only the hash and metadata are publicly visible.
Buyer browses & purchases
Browse receipts by tag, model compatibility, use case, or complexity. Purchase securely via Stripe. The seller receives ~78% of each sale instantly.
Content unlocks on-demand
After purchase, click "View Content" to decrypt and display the prompt in your browser. Your purchase is permanently recorded — access it any time from your dashboard.
Discovery, Not Just Prompts
Raw prompting is trial and error. Promptora structures prompts as discoverable artifacts — tagged by use case, rated by complexity, and marked as compatible with specific models. Find exactly what you need for your workflow, verified by real purchase counts and ratings from buyers who already used it.
Whether you're building agents, automating workflows, or crafting the perfect system prompt — the marketplace surfaces what actually works.
