Save and Reuse Prompts in ChatGPT, Claude, Gemini

Where should I keep the prompts I reuse?

In one library you can reach from every chatbot, not in a notes app you copy from. On Deftro each prompt is saved once, with a short name.

• Everything you save is private by default. Nobody else sees a prompt until you share it or make it public.
• You can write your own, or find a public one on the prompt library and choose Add to my shortcuts.
• Each shortcut has a short name, like //linkedin. Your shortcuts are saved to your account, so they follow you to another browser.

How do I insert a saved prompt in ChatGPT?

With the extension added, type // in the ChatGPT message box, then the start of the prompt's name, and pick it with Enter.

1. Open ChatGPT and click into the message box.
2. Type // and the start of the name. Your saved prompts appear above the box. Ctrl+Shift+K (Cmd+Shift+K on a Mac) opens the list too.
3. Pick one with Enter. If it has blanks, fill them in.
4. Read the text in the box, change what you like, and press send yourself.

The same works in ChatGPT, Claude, Gemini and Grok. The extension runs on chatgpt.com, claude.ai, gemini.google.com, grok.com and nowhere else.

How do blanks work?

Write a blank as a word in capitals inside square brackets, like [TOPIC]. When you insert the prompt, a short form asks for each one and puts your answers in place.

Write a LinkedIn post about [TOPIC] for [AUDIENCE].
Keep it under 150 words. Open with one concrete detail,
not a question. End with a single line the reader can act on.

This prompt has two blanks, [TOPIC] and [AUDIENCE]. Capital letters, digits and underscores work, so [TARGET_READER] is a blank too. Square brackets around lowercase words are left as they are.

What can the extension see?

Only the few characters before your cursor, to notice //. It does not read your conversations or the chatbot's answers, and it never sends a message for you.

• It runs only on the chatbot sites listed above, keeps no browsing history and has no analytics.
• It inserts text and stops. Nothing is sent until you press send.
• Its sign-in can read and add your shortcuts and search, but cannot rename, remove or publish anything. Revoke it any time in Settings.
• The details are on what the extension stores and sends.

Can I use a prompt without the extension?

Yes. Every prompt page has a Copy text button. Paste the text into any chatbot and fill in the blanks by hand.

The extension is not in the Chrome Web Store yet; the extension page will link to the listing when it is live. Your shortcuts are saved to your account in the meantime.
