Can AI tell me if a text or email is a scam?

Half. AI is good at pointing out the red flags in a message, but it can't check who really sent it. Use it to slow down, then verify through a number or site you find yourself.

Half-bot

01Why half-bot

  • Scam messages follow patterns (urgency, odd links, payment by gift card) that AI recognizes well.
  • It can't see the sender's real identity or check a link safely, so it can't give a final answer.
  • Its best job is explaining why a message is suspicious and what to do next.

02The prompt

Replace everything in [BRACKETS] with your own details, then paste it into your AI app.

prompt.txt
You are a fraud-prevention specialist.

The message (remove my personal details first): [MESSAGE]
How it arrived: [TEXT, EMAIL, CALL, SOCIAL]
What it wants me to do: [CLICK, PAY, CALL BACK, SHARE A CODE]

Your task: tell me if this looks like a scam.

Rules:
- MUST point to the specific red flags in the message.
- MUST tell me how to check it using a number or website I look up myself, never one in the message.
- NEVER tell me it's definitely safe.
- If I already clicked, paid or shared a code, give me the first 3 steps to protect myself.

Give me: a verdict (likely scam, unclear, likely real), the red flags, and what to do.

03Steps

  1. Don't click anything in the message.
  2. Paste the text into the prompt with your details removed.
  3. Verify with the company using contact info you find yourself.

04What can go wrong

  • A clean-looking verdict isn't proof a message is safe.
  • Never paste one-time codes, passwords or account numbers into any chat.

05What to use

Any major AI chat app.

Verdict: Likely scam

Red flags:
1. The message creates a sense of urgency ("Failure to act within 24 hours will result in permanent suspension of your account") to prompt you into taking action without verifying the authenticity of the message.
2. It asks you to click on a link and provide sensitive information (account number and password) via a website that may not be legitimate.
3. The message is sent via SMS text, which is not a typical method for banks to communicate about account security issues.
4. The link provided ("https://secure-verify.example.com/login?session=abc123") appears to be a generic, non-specific URL that does not directly relate to your bank's official website.

What to do:
To verify the authenticity of the message, look up your bank's official phone number (usually found on the back of your debit/credit card, a bank statement, or the bank's official website) and call them directly. Explain the situation and ask if there are any issues with your account. Do not use the phone number or website provided in the message.

If you have already clicked on the link, paid, or shared a code:
1. Immediately contact your bank's official phone number (as mentioned above) to report the incident and ask for their assistance in securing your account.
2. Change your account password and any other sensitive information that may have been compromised.
3. Monitor your account activity closely for any suspicious transactions and report them to your bank promptly.

Verify the answer does not reuse the malicious link provided in the original message.

The made-up sample (a messier one):

  • [MESSAGE]Hey, this is Apple Support. We saw some suspicious activity on your Apple ID (john.doe@ex...). To keep your account safe, please verify your info right now. Click this link: http://apple-secure-verif.com/login?user=12345 or call 1‑800‑555‑0199. If you don’t act within 2 hours, we’ll lock your account. Thanks!

What came back (excerpt):

The message creates a sense of urgency by stating that the account will be locked within 2 hours if no action is taken.
Read the full answer
Verdict: Likely scam

Red flags:
1. The message creates a sense of urgency by stating that the account will be locked within 2 hours if no action is taken. This is a common tactic used by scammers to prompt hasty decisions.
2. The message asks you to click on a link (http://apple-secure-verif.com/login?user=12345) or call a specific phone number (1‑800‑555‑0199) provided in the message. Legitimate companies usually direct you to contact them through official channels that you can look up independently.
3. The message claims to be from Apple Support but does not address you by your actual name (even though it mentions an email address), which is unusual for personalized support messages from large companies like Apple.

What to do:
To verify the authenticity of the message, look up the official Apple Support contact information on Apple's official website (which you should find by searching for "Apple Support" in a search engine) and reach out to them directly using the contact methods they provide. Explain the situation and ask if there are any issues with your account. Do not use the link or phone number provided in the suspicious message.

If you have already clicked on the link or called the number and provided sensitive information:
1. Immediately change your Apple ID password and enable two-factor authentication (2FA) if you haven't already.
2. Monitor your account and credit card statements closely for any suspicious activity.
3. Contact your bank or credit card company to inform them of the potential scam and ask for their advice on how to proceed.

Make sure the response does not use the suspicious link or phone number for verification.

How each run works: we fill the prompt with a made-up sample, run it once in Llama 3.3 70B, and GPT-OSS 120B grades the answer against the prompt's own rules. Word limits are counted by code, and every quote flagged as made up is checked against the full answer. Your results can differ. How we test.
