01

It reads the table

The rows come off the scan directly, not retyped by a model. A regex cannot misread a 6 as an 8.

02

It checks the arithmetic

A bill is a closed system of sums, so every sum is a free check. Failures name the row to look at.

03

It tells you something

Spend by category, effective tax, discount against MRP — and the odd thing your shop got wrong.

Not only receipts

The same engine handles a restaurant bill's service charge, a fuel slip's litres, an electricity bill's period and meter reading, a cab fare's surge, and a hospital invoice's advance payment — because a bill is modelled as items, adjustments, taxes and totals rather than as one shop's layout.

Chat and document search come with it, and Ask everything answers across whatever you've turned on: "how much on medicines last quarter" answered from your own filed bills.

Pricing

Where your bills go

Some processing happens off this server. Answering questions across your tools, anything without a route of its own and the chat tool use cloud: the text goes there to be understood and the result comes back here. Photographs never leave.

Everything else — indexing documents for search and reading your bills — runs on this machine.

We do not train on your data and the provider does not retain it for training. If that is not acceptable for your documents, the self-hosted build runs every model on your own machine instead.

Uploaded photos are never written to disk. They are read into memory, processed and dropped; what is kept is the extracted text and figures, encrypted at rest. You can delete any bill, or your whole account, and it goes.
