Features
Engineered for Flow
A system-wide AI launcher designed to keep your hands on the keyboard and your mind on the problem.
System-Wide AI Launcher
Summon PUCO from any application with a single global hotkey. It appears over your current app, you fill the form, copy, and it vanishes. Always one keystroke away, never in the way.

Who it's for
Real-World Workflows
The Explorer
Just getting started with AI? PUCO shows you what to ask — and how to ask it perfectly. Browse 100+ expert prompts and discover capabilities you never imagined, from photo restoration to comic book transformations. No prompt engineering knowledge required — just pick from a dropdown.
“I didn't know AI could do that until I saw the dropdown options. Now I use it daily.”
The Code Refactorer
Your prompt library, searchable and ranked by usage, one keystroke away. Build templates for code explanation, refactoring, and test generation with variables for language and framework. Prompt Memory lets you iterate — tweak the focus area, re-copy, compare outputs.
“Hit the hotkey, select 'Explain Code', pick the focus area from the dropdown, paste result. 5 seconds flat.”
The Brand Guardian
Manage multiple client accounts with templates that include brand guidelines as global suffixes. Smart forms ensure consistent tone, emoji style, and hashtag count every time. Prompt Memory means switching between client contexts is a single dropdown change.
“Switching between client contexts is a simple selection, not manual document hunting.”
The Data Analyst
Analyzing interview transcripts with consistent methodology. Templates ensure every interaction follows the same framework. Iterate rapidly by adjusting one parameter at a time while Prompt Memory keeps everything else locked in.
“Standardization makes research reproducible and findings defensible.”
