AI WORLD HQ
You've just spent 10 minutes crafting the perfect prompt to write a thank-you email. You hit send, it works, and you feel great. Then next week you need almost the same thing — and now you're staring at a blank screen, trying to remember what you typed last time.
Below is a step-by-step system for saving prompts so you can reuse them. It works in Apple Notes, Google Keep, Notion, Google Docs, or even a plain folder on your computer. You don't need any new software to start.
Before you start
What you need: A note-taking app or a folder on your device. Apple Notes, Google Keep, Notion, Google Docs, or a simple desktop folder all work. No paid plan, no special account, no AI tool of any kind — this is just you and your notes.
Time required: About 20 minutes for the first setup, then 30 seconds each time you save a new prompt afterward.
Works on: Phone, tablet, or computer. Pick whichever device you usually use when talking to an AI chatbot (a phone or laptop is typical).
Step 1 — Pick one place to store everything
Choose one app or folder and commit to using only that one. Mixing notes across three different apps is the fastest way to lose a prompt.
What to do: Open the app you'll use, create a new top-level folder or notebook called "AI Prompts" (or "My AI Recipes" if you prefer). Put it somewhere visible — at the top of your notes list, or pinned to your sidebar.
Where to find it: In Apple Notes, tap the folder icon at the top left, then "New Folder." In Google Keep, click "Create new label" in the left sidebar. In Google Docs, click "New" → "Folder." In a file browser, right-click your Desktop and choose "New Folder."
💬 Example folder name to copy: AI Prompts
You'll know it worked when you can see the new folder listed at the top of your app, and you can tap or click into it without searching.
Step 2 — Create subfolders by use-case
Inside your main "AI Prompts" folder, make 3 to 5 subfolders based on the kinds of tasks you actually do. Don't overthink this — you can rename or add more later.
What to do: Create subfolders like "Work Emails," "Study & Learning," "Personal & Family," and "Writing & Creative." If you mostly use AI for one thing — say, work emails — start with just two subfolders and split later.
Where to find it: In Apple Notes, open your "AI Prompts" folder, then tap the three-dot menu → "New Subfolder." In Google Keep, open the label, then click "Create new label" at the bottom. In Google Docs or a file browser, open the folder and create new folders inside it the same way you did in Step 1.
💬 Example subfolders to start: Work Emails, Personal & Family, Writing & Creative
You'll know it worked when you can drop a new note into a subfolder without it appearing at the top level by mistake.
Step 3 — Save each prompt as its own note, with a clear name
From now on, every time you write a prompt that works well, save it as a separate note right away — not later, not "when you have time." Later never comes.
What to do: Create a new note inside the right subfolder. Type or paste the prompt itself in the body, and give the note a clear title. Use the format: purpose — tone or style. For example: Thank You Email — Professional or Meeting Summary — Bullet Points.
Where to find it: In Apple Notes, tap the pencil-and-paper icon to start a new note inside the folder. In Google Keep, click "Take a note." In Notion, click the "+" next to the subfolder name. In Google Docs, click "+ New Document" from inside the folder.
💬 Example title to copy: Blog Outline — Friendly and Engaging
You'll know it worked when you can find the saved prompt again by scrolling the subfolder, even if you only remember the purpose and not the exact words.
Step 4 — Add a quick reference card under each prompt
A prompt on its own often isn't enough — three weeks later, you won't remember what it does or how to adjust it. So directly under each saved prompt, write four short lines.
What to do: Under the prompt, add:
- What it does: one line, e.g., "Writes a 150-word product description."
- Tone or style: e.g., "Casual but professional."
- Example output: paste the first result the AI gave you.
- Tweak notes: e.g., "Change 'product' to 'service' if needed."
Where to find it: Just type these four lines at the bottom of the same note you created in Step 3. No new menu, no extra click.
💬 Example reference card to copy:
What it does: Drafts a polite rejection email for job applicants.
Tone: Warm but firm.
Example output: "Thank you for applying... we decided to move forward with other candidates..."
Tweak notes: Replace [Company Name] and [Role Title] each time.
You'll know it worked when you can open the note and instantly see what the prompt does without re-reading the prompt itself.
Step 5 — Add tags or emojis so you can find prompts fast
Once you have 10 or more saved prompts, folder names alone start to feel slow. Tags and emojis let you spot the right one in seconds.
What to do: Pick a simple tagging rule and stick to it. Two easy options:
- Emoji prefix in the title: 📧 for emails, 🎓 for study, 📝 for writing, 💼 for work. So a full title might be
📧 Thank You Email — Professional. - Underscore keywords in the filename (if you use Google Docs or a file folder):
ThankYou_Email_Professional,MeetingNotes_Concise.
Where to find it: In Apple Notes, scroll to the top of the note list inside the subfolder — emojis are sorted automatically, so all your 📧 notes group together. In Google Keep, use the "Filter" icon at the top. In Google Docs, use the search bar with the emoji or keyword. In a file folder, sort by name.
💬 Example title with emoji: 📧 Follow-Up Email — Short and Friendly
You'll know it worked when you type one emoji (or one keyword) into the search bar and the right prompt appears within a second.
Step 6 — Review your library once a month
Prompts go stale quietly. An AI tool gets updated, your needs shift, and a prompt that worked in January starts giving weird results in March. A 10-minute monthly check keeps everything sharp.
What to do: Pick a day each month — the first Monday, the last Friday, whatever you'll remember. Open your "AI Prompts" folder and skim the titles. For any prompt you've used in the last month, open it and ask:
- Did it still work the last time I used it?
- Can I make it shorter or clearer?
- Have I learned a better way to ask this?
Where to find it: Just open the folder. No special menu needed. If a prompt needs updating, edit the note in place and add "Last updated: [month] [year]" at the very bottom.
💬 Example footer to copy: Last updated: March 2026
You'll know it worked when you can scroll through your folder and every prompt has a "Last updated" date from this year or last year — no orphaned notes from two years ago.
Common mistakes
- Mistake: Saving prompts inside the chat history of the AI tool itself. Fix: AI chat histories get cleared, archived, or rate-limited without warning. Always copy the prompt out into your own note app within a minute of writing it. The chat is for trying things; your library is for keeping them.
- Mistake: Naming prompts vaguely like "Email 1" or "Good prompt." Fix: Use the purpose — tone format from Step 3 every single time. If you can't tell what a saved prompt does from the title alone, the title is wrong.
- Mistake: Skipping the reference card because it feels like extra work. Fix: The 30 seconds you save by not writing it costs you five minutes later when you re-read the prompt and still don't know what it's for. Write the four lines the first time, not the fifth time you reuse it.
- Mistake: Letting the library grow to 50 prompts in one flat folder. Fix: Stick to the 3–5 subfolders from Step 2. If a new category keeps appearing, add a new subfolder. A flat list of 50 titles is the same problem as having no library at all.
