How to use ChatGPT as a personal assistant

An AI assistant can't book your dentist or move money. What it can do is absorb the thinking work around your commitments: planning, drafting, comparing, summarizing, and breaking things down. The people who get real value from it aren't using better prompts — they're using it at the same moments every week.

Routine 1: the five-minute weekly briefing

Once a week, paste in what's coming: appointments, deadlines, obligations, the errands you're carrying in your head. Then ask:

• What conflicts or looks unrealistically tight?
• What needs preparation before it arrives?
• What are the three things I should do first?

This is the highest-value habit for most households, because the problem is rarely a missing task list — it's never looking at the week as a whole.

Routine 2: daily triage instead of daily staring

When you can't decide what to start, dump everything and ask for a suggested order with reasoning. You'll disagree with some of it, and that disagreement is what gets you moving. Add: "If something looks like it should be dropped or delegated, say so."

Routine 3: draft first, edit second

Routine messages — declines, reschedules, thank-yous, complaints, follow-ups — should never start from a blank screen. Ask for a draft in your tone, then edit. If drafts consistently sound wrong, paste in three things you've actually written and ask the assistant to describe your voice, then save that description in your custom instructions.

Routine 4: a standing set of reusable prompts

Keep a note with five prompts you reuse rather than reinventing:

1. "Here's my week. Flag conflicts and three things to prepare."
2. "Turn this week's dinners into a grocery list grouped by aisle."
3. "Summarize this document in ten bullets, then flag anything unusual."
4. "Compare these options in a table with tradeoffs and what's unclear."
5. "Break this into steps and tell me the smallest one I could do in ten minutes."

Routine 5: the weekly review

Ask the assistant to interview you: "Ask me five questions to review my week and set up the next one." Being asked is much easier than remembering what to reflect on.

What to keep out of it

An assistant that knows your schedule shape and preferences is useful. One that holds your credentials, account numbers, identifiers, or medical records is a liability. Keep those out entirely, and check your employer's policy before pasting work material. AI output can also be confidently wrong — verify dates, prices, and anything with consequences.

Where to start

Pick one routine — the weekly briefing is the usual winner — and run it for two weeks before adding another. If you'd like a personalized shortlist instead, take the free AI assessment.

An assistant works better when it knows your week. Building a Personal AI Profile takes a few minutes and gives you starter prompts based on your own routines.
