How it works

Three steps. Zero typing.

Payhay runs quietly in the background. The moment your bank notifies you of a transaction, it's already in your ledger.

1

Your bank sends a notification

Exactly the same push alert you already get today — nothing new to install on the bank side.

2

On-device AI reads it

A small AI model running entirely on your phone works out the amount, currency and whether it's money in or out.

3

Saved automatically

The expense appears in your list instantly — no forms, no receipts to photograph, no manual entry.

One-time setup

A 30-second step for some banks

Most banks work instantly.

A few banks keep "balance-change" notifications turned off by default. If yours does, turn it on once in your bank's app — Payhay can't read a notification that never arrives. Here's the MB Bank example (Vietnamese Bank):

Step 1
MB Bank account screen — tap Biến động số dư (balance change)

Open your account details and tap "Biến động số dư" (balance change).

Step 2
MB Bank notification settings — select Nhận biến động số dư qua APP MBBank

Choose "Nhận biến động số dư qua APP MBBank" (receive via the MB app).

Step 3
MB Bank toggle — turn on Nhận thông báo

Turn on "Nhận thông báo" (receive notifications) for this device. Done — for good.
