Prompt architecture

Turn a plain sentence into a prompt built for your model.

PRISM refracts what you ask into its component pieces — objective, platform, constraints, style — then recombines them into an engineered prompt tuned to the exact AI you'll run it on. Then refine it in plain language until it's right.

No account needed to build
01

Decompose

Your request is split into what you want, the tools to use, and how to phrase it.

02

Tailor

The prompt is written to fit your target model and tuned to where you'll run it.

03

Explain

It shows the reasoning behind the prompt, plus which tools to run it with and why.

04

Refine

Tell PRISM what to change in plain words. It rewrites in place and keeps a history of your revisions.
