Yes, in a few places, and no, in the places the hype wants you to believe. AI saves you money when it finds value you own: inbox rewards, forgotten subscriptions, bills worth negotiating. It costs you money when it shops on a retailer's behalf. I run Majir, so I have a stake. This is part of our Value Watch series.
Where does AI actually save people money?
Inbox scanning is the most honest money AI can find. The average inbox is a filing cabinet of unclaimed value. Retailers send rewards, loyalty points, coupons, and cashback to everyone who signs up, and most of it expires unused. Majir connects to your Gmail or Outlook with read-only OAuth 2.0 access, scans promotional email, and surfaces it all in one dashboard with expiry alerts. No passwords are stored, access is 256-bit encrypted and revocable anytime. The money is not invented by AI. It is money you already earned and forgot to use.
Subscription tracking is real, and it is already a proven business. Forgotten subscriptions are pure waste, so this works. Read the fee model before you connect a bank account. Price comparison works when you give AI a spec, not a vibe. Tell it exactly what you want and the output is useful. Negotiation is a genuine money move: bill negotiation is slow and tedious, which is why people pay for it. AI makes it cheaper to try. Just ask what the service keeps before you sign.
Where does AI not save people money?
The buzziest AI money product is the shopping assistant, and it is the one I trust least. OpenAI launched shopping research in ChatGPT in November 2025. Its own guidance warns the feature might make mistakes about product details like price and availability and tells you to check the merchant site. A shopping agent that recommends the wrong item at the wrong price does not save you money. It creates a transaction.
Coupon extensions already showed us how this ends. A free extension that earns affiliate commissions works for the retailer that pays it, not for the shopper. The lesson: when a tool is free and a retailer pays it, the tool works for the retailer. Your coupon hunt becomes a commission event. The click is the product.
Agent fees and subscriptions are the tax on the hype. The newest money apps charge you to hunt for money: monthly memberships, percentage cuts on negotiated savings, affiliate revenue from the retailers they recommend. Add them up and the tool can cost more than it finds. A tool that asks you to pay before it proves it can save has already spent your money.
How do the AI money tools compare?
| Tool | How it works | What you give up | Best for |
|---|---|---|---|
| Inbox savings scanner (Majir) | Read-only inbox scan finds rewards and loyalty value you already signed up for. | Read-only inbox access, revocable anytime. | People who want to use value they already own. |
| Subscription manager (Rocket Money) | Finds and cancels your forgotten subscriptions. | Bank and subscription logins. | People with forgotten subscriptions. |
| AI shopping assistant (ChatGPT Shopping) | Turns a shopping question into a buyer's guide. | Your shopping history; price and availability can be wrong. | Product research, not price hunting. |
| Coupon extension (Honey) | Tries coupon codes while you pay and earns an affiliate commission on the sale. | Your browsing data and a purchase that becomes a commission. | Researching how coupon extensions work, not relying on them for savings. |
How do I know an AI savings tool is worth it?
Ask three things. Does it make money when you save, or when you spend? A tool that profits from your purchase is a sales channel. Can you revoke access? If you cannot disconnect cleanly, it does not respect you. Does it surface value you own, or push purchases you did not plan? Finding the coupon you already have is a money move. Finding a new thing to buy is advertising.
What about Majir?
Majir is the tool I would build anyway. Maxwell Eichie and I founded it in 2025 to solve one problem: inbox value expires while you are not looking. It scans promotional email from trusted brands only, organizes money moves by category, and supports multiple accounts. Majir is live on iOS and on Google Play.

FAQ
Is it safe to connect my inbox to a savings app? It can be. Majir uses read-only OAuth 2.0, encrypts at 256-bit, never stores your password, and lets you revoke access anytime.
Do AI shopping assistants save me money? Not reliably. They recommend products, and their makers' own guidance says price and availability details can be wrong. Verify the price yourself.
What is the difference between Majir and a coupon extension? A coupon extension hunts for codes when you are already paying and can profit from your click. Majir surfaces the rewards and loyalty value you already signed up for and marks used money moves as Saved.
