Prompt Library tool for everyone.
Camurj is a prompt library that lives in your browser's side panel. Ready-to-use prompts across every category — browse them, fill in the brackets, and send the result straight to Claude or Gemini.
How it works
Open the side panel
The library sits beside whatever you're doing. No new tab, no hunting through old chat threads or saved notes.
Pick one, fill the brackets
Search or filter by category, then edit the prompt inline — placeholders like [TOPIC] or [AUDIENCE] get filled in on the spot.
Send it where you work
One click opens Claude or Gemini with the prompt already in the composer. Or hand it to Claude Desktop, or copy it anywhere else.
Fix a prompt on the spot
Send a prompt you're drafting yourself instead of picking from the library. It comes back rewritten — clearer and more precise — immediately, ready to copy.

Frequently asked questions
Is Camurj free?
Camurj starts with a 14-day free trial — full access to the library and every feature, with no card required. After that, continued access is supported through Patreon. Prompts you've already copied are yours to keep either way.
Which AI models does it work with?
Camurj sends prompts directly to Claude and Gemini in the browser, and can hand off to the Claude Desktop app. You can also copy any prompt to your clipboard and paste it into any other tool you use.
Can I edit the prompts?
Yes. Every prompt is editable directly in the side panel before you use it, so you can fill in the bracketed placeholders or rewrite anything you like. Edits apply to the prompt you're about to send.
Can you see the prompts I use?
Only for one feature. Browsing, copying, and sending prompts happens entirely in your browser and never reaches us. The exception is "Check your prompt" — when you use it, the text you wrote is sent to our server to be rewritten, then returned to you. It isn't stored or used for anything else. Details are in the privacy policy.
Why does Claude show a caution message when I send a prompt?
Claude shows that notice whenever prompt text arrives from outside its own interface, which includes any browser extension. It is a standard safety measure, not a sign that anything is wrong. Camurj only places the prompt into the message box for you to read — nothing is sent until you press Enter yourself.
Which browsers are supported?
Chrome, and Chromium-based browsers that support the side panel API, such as Edge and Brave. Firefox and Safari aren't supported yet.

Camurj comes with a 14-day free trial. After that, access is supported by the people who use it — a few dollars a month covers hosting, the API costs behind prompt refining, and the time spent adding new prompts.
