Check a quote or official letter before you pay or sign

Photograph an official letter, a fine or a tradesperson's quote. ChatGPT, Claude or Grok explains it in plain words, flags anything unusual compared with typical terms, and drafts a polite reply with the right questions. It won't tell you the exact fair price, so you check sourced ranges and get a second quote before you pay or sign.

πŸ“Έ What it looks like

Two examples of the kind of answer you can get. These are illustrations we made, not real app screens and not real customers' documents.

Illustration
πŸ‡ΈπŸ‡¬ Singapore Β· aircon
πŸ“· Your photo: aircon service invoiceBooked: general service, S$40/unit
On the day: "Chemical wash required" S$280/unit Β· pay now
What does this mean? Anything unusual?

In plain words: you booked a basic service, and now they say you need a pricier one.

⚠ Worth checking: a wash pushed on the spot, with no inspection shown, is a known upsell pattern.

For comparison: guides list about S$80–150 per unit for a chemical wash (market guides, not official; I can't know your real cost).

Ask: Can you show me why it's needed? Can I have an itemised price? Can I decide later?

Illustration
πŸ‡¦πŸ‡ͺ Dubai Β· painting
πŸ“· Your photo: painting quotePainting, 4-bed villa
Advance 50% (cash) before work starts
Is this normal?

⚠ Worth checking: a 50% cash advance with no milestones is a common warning sign.

For comparison: market guides describe about 20–30% upfront, then staged payments, with 5–10% held back until snagging is done (market practice, not law).

Ask: Can I pay in stages by bank transfer to the company? Can I see your trade licence? Can we put the full scope in writing?

βœ… 0 of 9 steps done πŸ“„ Printable page
  1. 1
    ☐

    Open your AI app

    Use whichever you like: ChatGPT (chatgpt.com or the ChatGPT app), Claude (claude.ai or the Claude app) or Grok (grok.com, the Grok app, or the Grok button in X). Sign in with a free account and start a new chat.

  2. 2
    ☐

    Cover private details first

    Before you take the photo, cover or crop out your NRIC/FIN or Emirates ID number, bank and card numbers, and anything you wouldn't post online. The AI doesn't need them to explain the document.

  3. 3
    ☐

    Snap the page and add it to the chat

    Lay the page flat in good light and photograph every page, including the small print. In the chat, tap the + or paperclip (attachment) button, or the camera icon, and pick your photo. Then paste the 'Read my photo' prompt below.

  4. 4
    ☐

    Check it read the photo correctly

    Compare the AI's typed-out version with the paper, especially prices, dates and percentages. If anything is wrong, tell it the correct figure before going on. AI can misread photos.

  5. 5
    ☐

    Get it explained in plain words

    Paste the 'Explain it in plain words' prompt. You'll get who sent it, what they want, by when, and what any jargon means.

  6. 6
    ☐

    List red flags against typical terms

    Paste the 'Red flags vs typical terms' prompt, and paste in the matching price range from the 'Market guides' table on this page. The AI points out unusual lines, like a big deposit, cash only or vague extras. It can't tell you the exact fair price, and nor can we.

  7. 7
    ☐

    Draft a polite reply with questions

    Paste the 'Polite reply with questions' prompt. Read the draft, change anything that doesn't sound like you, and send it yourself. Asking questions in writing also gives you a record.

  8. 8
    ☐

    Run the before-you-pay checklist

    Paste the 'Checklist before paying' prompt and tick each line yourself: deposit %, licence checked, written scope, staged bank transfers, no cash, and no paying while your goods are held. Anything marked 'To check' means wait.

  9. 9
    ☐

    Optional: if it looks like a scam, stop and report it

    Don't pay. In Singapore call the ScamShield Helpline on 1799. In the UAE, contact Dubai Economy and Tourism (DET) consumer protection on 600 545 555, Dubai Police on 901, or report online fraud at ecrime.ae. In an emergency, call the police.

πŸ’¬ Copy-paste prompts

Tap Copy prompt, paste it into your AI (Grok, ChatGPT, Claude or Gemini), then replace the [yellow bits] with your own details.

πŸ’¬ Read my photo (photograph a letter or quote)
I've attached a photo of a [letter / fine / quote / invoice] I received in [Singapore / Dubai, UAE].
First, type out exactly what the photo says, line by line, including every price, date, name, licence or registration number and any small print.
If any part is blurry or cut off, tell me which part instead of guessing. Don't explain anything yet.
πŸ’¬ Explain it in plain words
Now explain this document in plain, simple English, as if to a friend who has never seen one before:
1. Who sent it, and what is it (a quote, an invoice, a fine, an official letter)?
2. What are they asking me to do or pay, and by when?
3. What happens if I do nothing?
4. Any words or terms I might not understand, explained in one line each.
Keep it short. If you're not sure about something, say so rather than guessing. This is to help me understand it, not legal or financial advice.
πŸ’¬ Red flags vs typical terms
Compare this [quote / letter] with typical terms for [service, e.g. aircon chemical wash / 3-room HDB move / villa painting] in [Singapore / Dubai].
List anything unusual as a red flag, for example:
- a deposit above [20% in Singapore / 30% in the UAE]
- cash only, or payment to a personal account
- payment demanded before the work is done, or while my things are held
- missing line items or a vague scope
- extras or surcharges that weren't explained up front
- no company name, licence or registration number
- pressure to decide today
- promised or guaranteed returns
For each red flag: quote the exact line, say why it matters, and say what a normal version usually looks like.
Here are price ranges I found in market guides (not official): [paste the ranges from the USE CASy page, e.g. chemical wash S$80-150 per unit]. Tell me whether the quote is inside or outside them, but do NOT tell me an exact fair price: say clearly that you can't know the real cost without an inspection.
Finish with a short list of things I should check myself.
πŸ’¬ Polite reply with questions
Draft a short, polite reply to [company or person's name] about this [quote / letter]. I'm not accusing them of anything.
I want to:
- thank them
- ask [3-5] clear questions based on the red flags above (for example: an itemised breakdown, exactly what's included, their company registration and licence number, whether I can pay in stages by bank transfer to the company account, and what happens if extra work is needed)
- say I'll decide once I have their answers.
Tone: friendly and firm, British English, no threats, no legal language. Under 150 words, so I can send it by [WhatsApp / email].
πŸ’¬ Checklist before paying
Before I pay anything for [service] in [Singapore / Dubai], turn this into a yes/no checklist I can tick, based on the quote and our chat:
- Deposit: what % is it? Is it [20% or less in Singapore (the CaseTrust renovation cap) / about 20-30% or less in the UAE (market practice, not law)]?
- Licence: have I checked the company name and licence or registration number myself (for example HDB's renovation contractor directory, the CaseTrust list, or the UAE trade licence)?
- Written scope: is every job, material and price written down, with extras agreed in writing before they're done?
- Staged payments: am I paying in stages as the work is finished, with some held back until defects are fixed?
- Bank transfer: am I paying the company's bank account, not cash and not a personal account?
- Goods held: am I being asked to pay before my things are unloaded or handed back? If yes, flag it.
- Second quote: have I got at least one other quote?
Mark anything I can't answer yet as "To check". Don't make up answers for me.

⚠️ Tips & common mistakes

🧾 Real examples: Singapore and the UAE

These are reported cases and patterns, shown as the source reported them, with links. Where a case is disputed, we show both sides. Words in quotation marks are copied from the linked source.

πŸ‡ΈπŸ‡¬ Singapore Β· moversS$228 quote, S$1,796 bill

A woman moving from Serangoon to Kovan was quoted S$228, then charged S$1,280 in "long pushing distance" fees on moving day, bringing the bill to S$1,796.

The customer says she had to pay when the movers arrived, before her belongings were unloaded. The company says its T&Cs exclude such fees and that she declared five or six boxes.

Red flags: extras hidden in the T&Cs, an uncapped per-distance fee, paying while your goods are still on the truck.

πŸ“° Mothership, 15 Sep 2026 β†—
πŸ‡ΈπŸ‡¬ Singapore Β· airconA cheap service that becomes a chemical wash

An aircon company describes firms that "quote general service prices to get the booking, then upon arrival, insist that chemical wash is 'actually required.'" Another writes: "A $50 chemical wash that becomes $300 after extra parts or additional cleaning is a pattern we hear about regularly."

Red flags: a wash recommended without running or inspecting the unit, pressure to decide on the spot.

πŸ‡ΈπŸ‡¬ Singapore Β· airconA "gas leak" in a unit that was cooling fine

A Reddit user said a technician told them their condenser was leaking gas, although the unit was cooling well, and wanted about S$380 to fix the leak, clean the condenser and top up the gas. Commenters said it's a common upsell.

Red flags: a diagnosis that doesn't match what you see, several extras bundled together, no gauge reading or evidence shown.

πŸ‡ΈπŸ‡¬ Singapore Β· renovationDeposits paid, then the firm went quiet

About 20 households say they paid deposits to Axion Design before it stopped responding. One homeowner paid S$76,000. Police are investigating.

The founder says: "This is not a scam … because if it is a scam, I think I won't be here talking to you."

Red flags: a large deposit early, a "refundable" promise that isn't in the contract, a very young firm.

In 2024, CASE said renovation caused about S$728,000 of prepayment losses, more than any other sector.

πŸ‡ΈπŸ‡¬ Singapore Β· locksmith (disputed)A call-out fee nobody agreed in writing

A locksmith charged an elderly woman S$80 after the door was opened before he arrived. He told AsiaOne: "I asked if I could trouble her to relay the message that my fees are $120, no cancellation allowed." He later filed a police report over harassment after the story spread.

Lesson: get the call-out and cancellation fee in writing before anyone is sent. This is about unclear terms, not proven fraud.

πŸ‡¦πŸ‡ͺ Dubai Β· paintingA 50% cash advance, then silence

A Reddit user in Dubai said a painter took a 50% cash advance to paint their villa, then disappeared for weeks and stopped answering calls. They said the police told them it was a matter for the courts.

Red flags: a 50% advance, cash only, no milestone contract.

πŸ‡¦πŸ‡ͺ Dubai Β· renovation80+ homeowners out of pocket

The National reported that more than 80 homeowners and hundreds of subcontractors lost "millions of dirhams" when renovation firm Signature Living ran into trouble.

The company says an executive took cash from clients without permission, and it is "not requesting and not accepting cash payments".

Red flags: cash handed to an individual instead of a bank transfer to the company, no receipt on company letterhead.

πŸ“° The National, Mar 2025 β†—
πŸ‡¦πŸ‡ͺ Dubai Β· appliance repairA fake "authorised agent" with 600 receipts

Dubai Police arrested a man who claimed to be an agent for several appliance brands and used three websites to advertise repairs. Police found 600 customer receipts.

Red flags: a site using brand logos that the brand's own website doesn't list, payment before the repair.

πŸ“° The National, Oct 2022 β†—
πŸ‡¦πŸ‡ͺ Dubai Β· AC ductsAED 99 "full duct clean", then a "mould" upsell

One cleaning company warns: "Watch out for companies advertising full duct cleaning for AED 99 or AED 149." Another lists "Mould detected, you need our premium package" as a classic upsell line.

Red flags: a price far below the market, a quote with no site visit, a mould claim with no photo or camera footage.

A man who posted a fake maid-services ad on WhatsApp agreed a Dh3,500 fee and said "a Dh2,000 deposit must be made on the spot", then went silent. A court fined him Dh4,000. (A maid agency, but it's the same pattern seen with home services.)

Red flags: a WhatsApp-only business with no licence, same-day urgency, a deposit sent to a personal account.

πŸ“‰ Investment "trader" messages: 5 patterns police and regulators warn about

If a message promises returns, no price check is needed: these are warning signs on their own. AI can help you spot them, but always verify the firm on the official register.

πŸ‡ΈπŸ‡¬ Singapore Police"Free investing lessons" chat groups

At least 48 cases and S$3.6 million lost since May 2026. "Mentors" and fake "members" share profit screenshots; some victims get small "initial returns" first.

Red flags: an ad that leads to a chat group, a mentor, transfers to personal accounts, blocked withdrawals.

πŸ‡ΈπŸ‡¬ Singapore Police"Pump and dump" share tips

"Mentors" push small overseas-listed shares, and some promise to reimburse losses. Police: "No investment or trading strategy can guarantee profits."

Red flags: buy-now urgency, little-known overseas shares, promises to cover losses.

πŸ‡¦πŸ‡ͺ UAE regulator"Up to 10% monthly profit"

UAE residents were told to verify licences as scammers promise "up to 10% monthly profit". The regulator named several unlicensed firms.

Red flags: a fixed monthly return, no listing on the regulator's register.

πŸ‡¦πŸ‡ͺ DFSA alertFake "regulator letters" asking for fees

An advance-fee scam used a lookalike website and fake letters with a stamp bearing the DFSA's name. The DFSA: it "does not permit Authorised Firms to use company stamps bearing the DFSA's name."

Red flags: a fee to release or withdraw money, a lookalike web address, a regulator stamp on a letter.

πŸ‡¦πŸ‡ͺ Dubai PoliceHigh-return trading offers by ad or DM

Dubai Police say legitimate platforms "do not guarantee fixed returns or risk-free profits" and don't ask for urgent payments outside official channels.

βœ… The official numbers: Singapore renovation (CASE / CaseTrust)

  • CaseTrust-accredited renovation firms cap the initial deposit at a maximum of 20% of the total cost, and "payments are collected in phases upon agreed milestones".
  • They must buy a deposit performance bond, use the standard renovation contract, agree variations in writing before the work, and give a 12-month workmanship warranty.
  • CASE's homeowner guidance also suggests holding back part of the payment (5–10%) until defects are fixed.
  • For HDB flats, the contractor must be on HDB's Directory of Renovation Contractors.

🌟 Why it's worth it

πŸ’‘ Why it mattersSurprise extras and lost deposits are common in Singapore and the UAE. CASE says renovation alone caused about S$728,000 of prepayment losses in 2024. Ten minutes checking the deposit size, written scope, licence and how you pay helps you spot warning signs before money changes hands.
🏷️ Real exampleA Singapore mover quoted S$228, then billed S$1,796 on moving day, with payment taken before her things were unloaded, the customer says. The company says its T&Cs exclude those fees and that she declared fewer boxes (Mothership, Sep 2026).
