A new iPhone app slipped onto the App Store yesterday, and the interesting part isn’t the app. It’s the one sentence you type into ChatGPT to make it work. The developer behind it, a Redditor who goes by u/Truffle_Journal, built the tool after watching the same problem repeat. You find a great prompt, tweak it for your work, then lose it the moment you leave the chat. Next time you need it, you’re digging through old chats or some random notes app, hoping you saved it somewhere.
Truffle Journal is a Markdown note app for iPhone that connects straight to ChatGPT. Your saved prompts live there as editable notes, and ChatGPT can reach in and pull them up on command. That’s the actual shift here: retrieval by name, inside the same chat you’re already in.
The twist
You don’t open the app to grab a prompt. You just ask ChatGPT for it, mid-conversation, in plain language. The original poster’s example request looks like this:
Find my “Article critique” note in Truffle and use its prompt to review this draft.
ChatGPT reaches into your notes, finds the instructions, and runs them on whatever you paste next. No tab switching, no copy-paste from a separate app, no scrolling through old chats to find the version you edited last week.
The trick only works because of one design choice. The reusable instructions live separately from whatever changes each time you use them. A note titled “Article critique” can hold a standing prompt like this one, saved word for word:
Review the draft below for unclear claims, repeated ideas, and missing context. Quote each passage that needs attention and explain why. Give feedback only, don’t rewrite the draft.
Draft: [insert draft]
The instructions stay fixed. The draft slot is whatever you’re working on that day. Split those two apart and a prompt stops being something you retype and becomes something you retrieve.
How to try it
- 📲 Download Truffle Journal from the App Store and open the built-in tutorial. It’s three guided steps and takes about two minutes.
- 🔗 Connect the app to ChatGPT once. After that, ChatGPT can read and write your notes without you opening Truffle again.
- ✍️ Save a prompt as a note straight from a ChatGPT conversation. Edit the wording on your phone until it says exactly what you mean.
- 💬 In any new chat, ask ChatGPT to find that note by name and use its instructions, then paste in whatever’s different this time.
Finish the tutorial and the developer throws in a free month of ChatGPT Plus, no extra signup required.
Pro tips
Name your notes for how you’ll ask for them later, not for what’s inside them. “Article critique” is easy to request in a sentence. “That long prompt I wrote for reviewing drafts before sending to my editor” is not. Short, specific, nameable titles are what make the retrieval trick actually work.
Keep the note free of anything that changes between uses. The moment a note mixes standing instructions with one-off details, like a specific email or a specific date, it stops being reusable. Split it into a clean template and paste the changing part fresh every time.
If you’ve got five or six prompts you lean on constantly, that’s five or six named notes. That turns a folder of half-remembered text into a library you can summon by name mid-chat, without ever leaving the conversation.
This also works for more than single-shot prompts. Stack a few related notes, like “Article critique,” “SEO headline check,” and “Tone pass.” Name them in order inside one conversation and you’ve got a lightweight editing pipeline, no separate app or workflow tool required.
Worth noting: this is iPhone only for now, and you do need that one-time ChatGPT connection before any of it works cold. The app also isn’t a day-one release. The original poster mentioned six months of TestFlight testing behind it, with the interface shaped by beta feedback the whole way through.
The usual prompt-storage tools stop at “save it somewhere.” Notion pages, plain notes, browser bookmarks, a doc titled “prompts” that nobody reopens. They hold the text fine, but you still have to leave the chat, hunt it down, and paste it back in by hand. Truffle Journal skips that last step by letting ChatGPT do the hunting for you, inside the same conversation where you’ll actually use it.
If you’re the type who rebuilds the same prompt from memory every few weeks, this is worth five minutes 🧭. Grab it from the App Store, run the short tutorial, and see if asking for a note by name finally kills the copy-paste dance.
