AI Expense Tracking On Your Phone
Receipt photos become structured expenses with AI that runs entirely on your phone. No account, no cloud, fully offline.
Nobody loses track of their money on purpose.
Logging every coffee, taxi and 7-Eleven run by hand is tedious. You keep it up for three days, skip one, and by the end of the month you're squinting at your balance wondering where it all went.
Most expense apps just hand you a faster form to fill in — still homework you'll quietly abandon by week two.
So SnapSpend doesn't make you enter anything at all.
SnapSpend does the tedious part for you.
Your receipts already exist
In Thailand, every bank transfer and QR payment drops a slip into your photos. Point SnapSpend at that album once — that's the whole setup.
It files them automatically
On your phone, SnapSpend reads each new slip — merchant, amount and date — and saves it as an expense. No typing. (Snap a paper receipt too, if you like.)
Just ask, in English or Thai
Later, ask the on-device AI "how much did I spend on food this month?" It answers from your own data — tuned for real Thai and English slips.
Two small models. Both on your phone.
fine-tuned · on-device · offlineThe actual pipeline — from a receipt image to a stored expense, and from a question to an answer. Every step runs locally; nothing is uploaded.
Receipt image
A payment slip from your photos, or a snapped paper receipt.
Read the raw text
Lifts every character off the image — including Thai.
Is this actually a receipt?
Checks for document text and a receipt layout before anything is trusted.
Structure the data
The custom model turns loose text into merchant, amount, date and line items.
Saved on your device
Filed as an expense in a local database. No copy is sent anywhere.
