About this tool

Razn is where hard decisions get structured. Define the problem, break it into an issue tree, run the numbers, and write the answer as a document and a deck. An AI team does the legwork and stops for your review after each step, so the reasoning stays visible and yours. Issue trees live on an infinite canvas; quant cards keep every number tied to an assumption. Export decks to PowerPoint or PDF and documents to Word. One plan, $15/month, everything included; you connect your own AI model access.
