VSTREL

We know how AI works. So we build products that work.

VSTREL is an engineering-led AI company. We design around what AI does well and where it fails, and turn it into products people can rely on every day.

How we build

01

Products, not projects

Each product is self-serve and built to serve many customers at once, not made to order for one client at a time.

02

Grounded and tested

Answers come from real data, numbers are calculated rather than guessed, and every release is tested against realistic scenarios first.

03

People keep the final say

People set the rules and AI follows them. Anything outside the rules still goes to a person to decide.

Products

Paibook

Internal use

An AI bookkeeping assistant in LINE for small businesses in Taiwan. Snap or upload a receipt, invoice or e-invoice and it is recorded, categorised and checked for input-VAT deductibility. Business-tax (401) figures and financial statements are compiled automatically, with reminders before each filing deadline.

Paibook is a tool for businesses to keep their own books and file their own returns; it does not provide bookkeeping or tax-filing services on anyone's behalf. It is currently used only within our own company.
