PromptPerfect alternative
Looking for a PromptPerfect alternative that works where you already write?
PromptPerfect has shut down. Patkan is a browser extension that turns a rough thought into a structured prompt inside ChatGPT, Claude, Gemini and other AI chats. Type what you need, end the sentence with //, then review the rewritten prompt before you send it.
PromptPerfect alternative, at a glance
PromptPerfect focused on improving prompts through its own product experience. Patkan works inside the AI chat you already use. There is no separate prompt workspace to open, copy from, or move between.

PATKAN RETURNS
## Role You are a B2B sales professional who writes short, respectful follow-up emails. ## Context A prospect attended a product demo and has not replied since. ## Task Write a follow-up email that restarts the conversation without pressure. ## Constraints - Under 120 words - Reference the demo once - One clear, easy next step ## Output format Subject line, then the email body.

How Patkan works
- 01
Write your request in plain English
Describe the outcome you want. It does not need to be formatted as a prompt.
- 02
End it with //
Patkan only activates when you deliberately add // at the end of your sentence.
- 03
Review the structured prompt
Patkan rewrites the thought in the input box. You remain in control of what goes to the AI model.
Why people use an in-chat prompt alternative
The hard part is not opening another prompt tool. It is remembering prompt structure while you work.
A useful AI prompt usually needs context, a clear task, boundaries and a requested output format. Patkan turns a rough instruction into that structure at the moment you need it—inside the ChatGPT, Claude or Gemini conversation already open.

No. Start with the outcome you want in ordinary language. Patkan supplies useful structure—such as role, context, task, constraints and output format—after you end the thought with //.
Does Patkan send text before I trigger it?+
No. Patkan activates only when you explicitly end the sentence with //. Review the rewritten prompt in the chat input before you send it.
