The Result

A complete message architecture tool

Not a template. Not a document. A working tool that turns a brief into a full message architecture you can share with your team.

What you'll walk away with:

✓ Situation and objective intake form
✓ Multi-audience input system with add and remove
✓ Primary message generator
✓ Audience-specific variant generator
✓ Proof points and guardrails with reasoning
✓ PDF export and copy-all button
✓ Runs on your computer

Curriculum

Five modules, start to finish

Each module builds one piece. By Module 5 you have a complete message architecture tool running on your computer.

Design the Intake

A form that captures the situation, objective, current state, and constraints

Add the Audience Layer

The form now captures who the audiences are and what they need to hear

Generate Messages

Click Submit and get a primary message plus tailored variants for each audience

Add Proof Points and Guardrails

Supporting evidence and a "what not to say" section with reasoning

Full Output, PDF, and Publish

Polished UI, downloadable PDF, live at a real URL
