Nothing leaves the page until //
Patkan takes no action until you deliberately end a sentence with two slashes.
For Google Gemini
A Gemini prompt generator that lives inside Gemini
Gemini answers best when a prompt has clear, unmistakable boundaries — role, context, task, constraints, output format. Writing that by hand every time is tedious. Patkan does it for you: type your rough thought on gemini.google.com, end it with //, and it becomes a structured Gemini prompt in the blink of an eye.
Before → After
Same thought. Surgically crafted for Gemini.
YOU TYPE

How it works
- 01
Type what you want
Open gemini.google.com and describe your task in plain, messy words. No structure needed.
- 02

Two slashes at the end of your sentence trigger Patkan. Nothing happens until then.
- 03
Watch it become sections
Your thought is replaced in place by a structured Gemini prompt — role, context, task, output format and constraints, each under its own clear heading.
Dialects, not templates
Gemini gets sections. Claude gets XML. ChatGPT gets markdown. Each model receives the structure it respects.

Questions
Gemini + Patkan, answered
Why does clear structure matter for Gemini?+
Gemini reads a prompt as one block of text. When the role, the task, the limits and the format are not separated, it fills the gaps itself — padding the answer with chatter, assuming details that were never given, or drifting away from what you asked. Plain uppercase section headings draw those lines for it. Patkan writes them for you.
Do I have to leave gemini.google.com to use it?+
No. Patkan is a browser extension that runs inside the Gemini tab. You type, you finish with //, and your text is rewritten right in the input box — no copying, no switching tabs.
Does it work in Google AI Studio too?+
Yes. Patkan runs on both gemini.google.com and aistudio.google.com, and applies the same sectioned structure in each.
What does Patkan actually do to my text?+
It compiles your rough thought into a structured prompt: it picks an expert role, adds the context and limits Gemini needs, and states the format you want back. You can read and edit the result before you send it.
Does it work with other AI tools too?+
Yes. The same extension works inside ChatGPT, Claude, Microsoft Copilot, Perplexity and more, with the structure adapted to each one. This page is about the Gemini dialect.
