Build Better Prompts, Faster
Stop writing prompts from scratch. Assemble them from modular, reusable components using proven frameworks. Your context stays with you - never stored, never shared.
The Problem
Too many people write AI prompts the same way they write emails - from scratch, every time.
- Inconsistent outputs that work once but fail to scale
- Wasted time on repetitive iteration cycles
- Knowledge about "what works" locked in individual heads
- Privacy concerns when storing sensitive context in cloud tools
The Solution
PromptMason introduces defined and modular prompt architecture to the desktop; assemble prompts from default frameworks, stacks and categories with reusable components.
- Consistent outputs using battle-tested frameworks
- 10x faster prompt creation with reusable blocks
- Shareable, standardized prompts across teams
- Session-only context - your data leaves when you do
How It Works
Think of it as a component-based design system for AI prompts
Choose a Stack
Select from 80+ proven prompt structures like COSTAR, RISEN, or PASTOR
Pick Components
Choose building block categories; Role, Context, Format, Constraints, Perspectives, Tone, Style, etc...
Customize & Mix
Edit components, combine frameworks, save your own variations
Copy & Use
One-click copy to any AI chat. Track with compact ID strings
Why PromptMason Is Different
Not just another template library; a fundamentally different approach to prompt building on the desktop
Modular, Not Monolithic
Unlike template libraries that offer take-it-or-leave-it prompts, PromptMason breaks prompts into interchangeable components. Swap out the Role while keeping the Format. Change the Constraints without touching the Examples.
Framework-Driven
We don't just give you prompts, we give you the structures behind them. Learn why COSTAR works for analysis, PASTOR for persuasion, and RISEN for precision. Then customize or create your own.
Compound Your Knowledge
Every Stack you create or customize can become part of your personal library. Over time, you build a Stack deck tailored to your work, not a folder of templates you forget you have.
Privacy by Design
Unlike tools that store your brand guidelines, audience profiles, and business context in the cloud, PromptMason leaves your sensitive data where it belongs - with you. Context is never parsed, never stored. No GDPR headaches. No data breach exposure.
