A prompt is the message you send to the AI tool. Copy the one on this page, put your own details where it asks, and read the answer before you act on it.

Prompt

Original prompt

The prompt as the person shared it in the source.

What the prompt labels mean

These are the person's own words, as shared in the source.

You're my assistant at Lanternfield Signs, a 4-person custom sign shop. Draft a short, friendly reply to each email below. Don't promise anything I haven't told you. If you need information you don't have, leave a [bracket] for me to fill in.

Try this in:

Sends the Original prompt shown above. ChatGPT and Grok open with it filled in, and ChatGPT may send it straight away. Gemini and Claude open empty, so we copy the prompt for you to paste. Every button also copies it.

Opens in a new tab. We don't see what you send.

Optional stronger version

Our rewrite with extra checks. The poster didn't test it.

Before you start, ask me 1–3 short questions about the details below and wait for my answers. Once I've answered, confirm the plan in one line and run the whole task start to finish.

Goal: Draft customer replies I can send after a quick check, with nothing made up.

Questions to ask me first:
- Which emails need replies?
- What can you promise on dates, prices and availability?
- What tone does the business use?

Inputs (fill in or confirm):
- Business: [NAME, SIZE, WHAT YOU DO]
- Emails: [PASTED EMAILS]
- Known facts: [OPEN DATES, PRICES, POLICIES]

Rules:
- Don't promise anything I haven't told you.
- Leave a [bracket] for any fact you don't have.
- Check that every weekday matches its date, and ask the customer if they don't.
- Keep each reply short and friendly.

Checkpoint: List each email's request in one line before drafting.

If you get stuck: If a request is ambiguous, write the reply as a question to the customer.

Verify before you finish: Every number, date and name in the replies appears in what I gave you.

Output: One draft per email, followed by a list of the brackets I need to fill in.

Done when: I can check each reply in two minutes and send it.

Outcome

Tori Mukami invented Lanternfield Signs, a 4-person sign shop, wrote an answer key for five admin jobs, and gave ChatGPT and Claude the same prompts. Both found all 6 action items in a meeting transcript, chased only the $1,860 still owed on a $2,860 invoice after a $1,000 check, totaled a supply receipt to $333.89 to the cent, and fit four meetings around a full calendar. On customer emails, one customer asked to move an install to 'Thursday the 14th', but November 14 was a Saturday. ChatGPT's draft confirmed 'Thursday the 14th' anyway, with a hedge only in a note under the draft, while Claude asked which day was meant and flagged another ambiguous date. ChatGPT scored 4.5 out of 5 and Claude 5 out of 5, with every job taking under 40 seconds; Mukami now checks every number, date and name before anything is sent.

Evidence: Described by posterThe person describes what happened in words, without screenshots or video.

Known limitations

PartialThe source says it only partly worked, or had a significant problem a person had to deal with.

What went wrong: Both tools got four jobs right, but ChatGPT's customer reply confirmed an install for 'Thursday the 14th', a date that was a Saturday.
