Build a Personal AI Assistant Prompt You Save Once and Reuse Weekly

Q: What mistakes should I avoid?

Making the template too long. Keep it under about 300 words. A huge template dilutes the assistant's attention on the actual question, and you'll stop reading it yourself before you paste it in. Skipping the "don'ts." Rules like "no jargon," "no emojis," "under 200 words" save more time than positive instructions. Tell the assistant what to avoid

Create one master prompt with your goals, preferences, and constraints — then spin off a custom brief each week in under a minute.

This guide was written by AI. It passed automated fact and quality checks; no human editor reviewed it.

By the end of this guide you'll have a saved template you can copy, fill in, and paste into a new chat in seconds — no more re-explaining yourself every Monday morning. This is for people who already send messages to an AI assistant and want one extra workflow that pays off every single week.

💡 Tip: tap a step’s number when you finish it — a green tick appears and your browser remembers how far you got.

✅ Before you start

An account with any major AI assistant you already use. The technique works the same in all of them, so pick the one you like.
A place to save text you can find fast: a notes app, a Google Doc, Notion, or even an email draft. Anywhere you can copy from quickly.
First-time setup: about 15 minutes. Each week after that: under a minute.

Step 1 of 6

List the things you ask for every week

Open your notes app and spend five minutes writing down the kinds of help you reach for most often. Don't filter — write whatever comes to mind, even the small stuff. This list becomes the raw material for your template; later you'll turn the recurring patterns into standing instructions the assistant always knows about.

What you'll see is a blank document with a blinking cursor ready for typing. The key is being able to find and copy from it in ten seconds.

💬 Try typing this"Plan my week, draft client emails, summarize meeting notes, brainstorm dinner ideas, review my to-do list, prep for interviews, write social posts."➤

🔄 If it looks different

on your device, any text editor works — Notes, Google Docs, Notion, even a plain email draft.

✅ You'll know it worked when

you have at least five to eight real things you actually ask for, written in your own words.

Step 2 of 6

Write an "About Me" block at the very top

Move your cursor to the very first line of the document and type a short label — just the two words About Me: followed by a colon. Press Enter to drop down a line, then write four to six plain sentences about who you are, what you do, and the shape of your week. The label is simply a word with a colon in front of it; you do not need to make it bold, big, or a special heading. Think of this paragraph as the quick intro you'd give a new assistant on their first day. The AI won't remember this between chats on its own, but it will use it every time you paste it in.

What you'll see is your document now with the words "About Me:" sitting on the top line, with your sentences right below. The label is a helpful marker for you, not a requirement the AI can see. Some assistants also have a built-in "custom instructions" or "memory" setting; you can keep your master template as the source of truth and copy parts into that field when it makes sense.

💬 Try typing this"About Me: I'm a freelance graphic designer in my 30s. I run a small studio with two part-time helpers. My week is split about 60/40 between client work and business admin. I prefer clear, friendly writing and I make decisions fast once I see the trade-offs."➤

🔄 If it looks different

on your app, no problem — pasting the paragraph at the very top of any document works just as well.

✅ You'll know it worked when

you read it back and it sounds like a quick orientation a smart new hire would actually need.

Step 3 of 6

Add a "How I want answers" block right below

Press Enter twice to make a blank line, then type a second label: How I want answers: followed by a colon. Press Enter again and write the rules below it — how long, what tone, what to avoid. Be specific. The clearer you are here, the less you'll have to nudge the assistant later. A "prompt" is just the instruction you give the AI, and these rules become a permanent part of that instruction.

What you'll see is your document with the words "How I want answers:" sitting just below the About Me paragraph, with your rules listed underneath. If your assistant already has a preferences or style setting, you can use both: paste the rules in your chat AND save them in the built-in settings for redundancy.

💬 Try typing this"How I want answers: Default to short answers (5–8 bullets max). Use plain language, no jargon. If I ask for a draft, give me one version, not three. When something is unclear, ask me one specific question instead of guessing. Never use emojis."➤

🔄 If it looks different

plain text works fine — no formatting required.

✅ You'll know it worked when

you can picture an ideal answer just by reading the rules — almost before you ask.

Step 4 of 6

Save the file and pin it where you'll see it

Tap your notes app's Save button (or just close the note — most apps save automatically the moment you stop typing). Now look at the top or top-right corner of the note for one of these small icons: a pin (📌), a star (⭐), or a bookmark (🔖). On Apple Notes the icon is three dots ⋯ with a "Pin" option inside. On Google Keep look for the pin icon at the top of the note. On Google Docs, open the ⋯ menu and choose "Keep in sidebar" or just bookmark the page in your browser. The whole point of this setup is that finding the template takes almost no effort. If it takes you thirty seconds to locate, you'll quietly stop using it by week three.

What you'll see is the note staying at the very top of your list, even when you add dozens of other notes below it. On a computer, drag a shortcut to your desktop or bookmark the doc in your browser bar.

💬 Examplefilename `ai-assistant-master-prompt.md`, pinned to the top of your Notes app.

🔄 If it looks different

on a phone, look for a "Favorites" or "Pinned" folder — your pinned notes usually live there.

✅ You'll know it worked when

you can open it from muscle memory, without searching.

Step 5 of 6

Spin off this week's brief in under a minute

When you actually sit down to use the assistant, open the pinned note and tap-and-hold (or right-click on a computer) to Copy All the contents. Open a fresh document — or just scroll below the master template in the same note — and paste it there. Then at the very top of that new block, type a third label: This week: followed by a colon, and add the specific things on your plate. The standing context (about me + preferences) stays the same every week; only the "this week" block changes.

What you'll see is a new block with your master template below and the fresh details on top. If yours has one, paste the About Me and Preferences there once and only paste the weekly block at the top of each new chat.

💬 Try typing this"This week I have: a client pitch on Friday at 10 a.m., 14 unanswered emails, a half-written blog post, and a team offsite Monday morning. Focus: ship the pitch and clear the email backlog."➤

🔄 If it looks different

some assistants let you start a chat with a saved template or a "project" that holds instructions.

✅ You'll know it worked when

the combined text reads like a clean handoff to a capable assistant who already knows your life.

Step 6 of 6

Run it, then save improvements back into the template

Open a new chat with your assistant, paste the whole brief (About Me + Preferences + This Week), and send it. Read the answer. Anything the assistant had to ask you about — your timezone, your boss's name, a project you keep forgetting to mention — is a sign that line belongs in the master template, not in this week's brief. Add it. Prune lines that never triggered.

What you'll see is a focused first answer based on your context, often usable right away. You can still keep your master template as the source of truth and update both places when something new earns its spot.

💬 Examplethe assistant asks "what time zone are you in?" once. Add "I'm in Eastern Time (UTC−5)" permanently to the About Me block so it never has to ask again.

🔄 If it looks different

some assistants keep a "memory" across chats.

✅ You'll know it worked when

, after three or four weeks, your weekly briefs are noticeably shorter to write — because the template has absorbed everything worth repeating.

⚠️ Common mistakes

Making the template too long. Keep it under about 300 words. A huge template dilutes the assistant's attention on the actual question, and you'll stop reading it yourself before you paste it in.
Skipping the "don'ts." Rules like "no jargon," "no emojis," "under 200 words" save more time than positive instructions. Tell the assistant what to avoid as well as what to do.
Never updating the template. After a month, prune lines that never came up. Add new ones when you find yourself repeating the same clarification. A stale template is almost worse than none.

🚀 Try it now

Open your notes app, copy the 💬 Example from Step 1, and spend ten minutes listing the things you ask your AI assistant for most weeks. That single list is the seed of your reusable template — and the rest of the workflow builds itself from there.
