Numero: Expense AI

Numero is the free AI expense tracker that tracks itself.

It reads your bank's transaction SMS and the receipts in Gmail and Outlook, sorts every payment, answers your questions, and keeps you on budget — without asking for your bank login.

No bank login required. Messages stay on your phone. Free to start.

Why Numero exists

Important financial details should not depend on memory.

Your bank texts you every payment and you swipe it away. Receipts land in email. Renewal notices arrive once and are easy to miss. By the end of the month, nobody can say where the money went, what they bought, or whether a promised refund arrived.

Numero keeps track of all of it for you. The aim is simple: know where your money went, stay on budget, and notice a useful detail before it becomes an expensive problem.

How Numero works

Connect once. Numero keeps watch.

01

Turn on SMS or connect your inbox

Numero reads your bank's transaction SMS on your phone, and Gmail or Outlook with read-only access. It cannot send, delete, or change anything.

02

Keep the useful details

Numero finds every payment, bill, subscription, refund and investment, counts each payment once, and saves details such as the merchant, amount and date.

03

Ask, budget, and get a heads-up

Ask Numero about your money in plain words, set budgets with alerts at 80% and 100%, and let AI Insights point out the changes that are easy to miss.

How we make decisions

We use AI, but we do not let it invent the facts.

01

Facts come first

Rules handle facts when the source is clear. AI can help explain or connect those facts, but it cannot quietly rewrite them.

02

We do not fill gaps with guesses

If a detail is missing or two sources disagree, Numero says so. An empty field is better than a confident but wrong answer.

03

Useful, not noisy

You should not have to check another endless feed. Numero points out the changes that may need your attention, and stays quiet otherwise.

04

Your data stays under your control

Inbox access is read-only and can be revoked. Numero does not sell user data, and you do not have to pay to disconnect a source, export your data, or delete your account.

Privacy and security

Know what Numero can see, what it keeps, and what you can remove.

It reads, it never writes

Bank SMS are read on your phone and personal chats are skipped. Email access is read-only: Numero cannot send, delete, label, or edit your mail.

It keeps details, not your mail

Numero does not keep SMS text, original email bodies, subject lines, attachments, PDFs, or images. It never sells user data.

An outside security review

Numero is Google certified for Gmail access. Google approved its read-only Gmail access after Numero passed the required CASA AL1 security assessment in 2026.

About Numero

A few things people usually ask.

What is Numero?

Numero is a free AI expense tracker and budget app. It tracks spending automatically from your bank's transaction SMS, Gmail and Outlook, plus anything you add by hand or scan. You can ask it questions about your money, set budgets, and get AI Insights about changes that are easy to miss.

Does Numero need access to my bank account?

No. Numero works from the transaction SMS your bank already sends you, the inbox you choose to connect, and anything you add by hand. It never asks for a bank or card login.

What data does Numero keep?

Numero keeps details such as the merchant, amount, currency, date, category and the last four digits of a card or account. It does not keep SMS text, OTPs, personal chats, email bodies, subject lines or attachments.

Is Numero a budgeting or accounting app?

Numero includes optional monthly and category budgets with alerts, built on the spending it tracks automatically. It is not a complete bank-synced ledger, accounting or tax tool, or a source of regulated financial or investment advice.

Company

Numero is early, and the founder still talks directly with customers.

Those conversations help decide what to build next, what needs more work, and where the product should be more honest about its limits.
