Curious? Have a look
You can open a preview of the app today. It is only for looking and testing — nothing real can happen there: nothing is sent, nothing is paid, nothing is saved as yours.
An AI-assisted tax and accounting app in development. Follow the progress, explore the demo and find the plan that fits you. The demo uses example numbers only — no real filing or payments.
Coming soon
February 2027 — the exact countdown will come.
It might also happen that I launch in Norway earlier than February — if so, I may keep developing further through February.
The demo app is open to everyone — look around and try, with example numbers. Nothing is sent or paid there. You can also explore the demo app from the menu at the bottom of this website.
Business & Invoicing
For Norwegian sole proprietors managing invoices, expenses and taxes.

Liable for Tax
Launching February 2027, if it's legal and the business is ready to go — the exact countdown will come.
An AI-driven tax and accounting app for crypto investors in many countries. Choose which country's tax you pay. It gathers your banks and crypto platforms, automatically follows the rules for your tax residency, keeps a running tax estimate, and prepares the report for the tax authority where you are taxable — in whichever country that is. You verify your identity with ID, so the app can never apply a country's tax that is not your own. You approve before anything is sent. Everything described here is included in the Exclusive subscription.
A running liability
A live estimate that follows your trading, so the tax year does not arrive as a surprise.
You approve before it is sent
Reports are prepared for the tax authority of the country where you are taxable — whichever country that is. Nothing is sent until you say so, with the Exclusive subscription.
No more uncertainty about your tax. The app follows your tax residency automatically and calculates 100 % of what you owe. You identify yourself with ID, so the app can never apply a country's tax that is not your own. Any extra payment is your choice — up to 20 % — and the surplus comes back at settlement. Connect every account you have and flag the ones the app cannot reach yet. Reviewed continuously.
Advanced systems can make mistakes. Everything the app prepares is quality-assured before it reaches you, and you always see the numbers and approve them before anything is sent. Where something matters to you, check it — you are the one who's responsible for your income.
Our AI-powered platform is designed to help users calculate their potential tax obligations based on applicable tax rules, transaction data, and their tax residency.
By combining automated calculations with country-specific tax information, we aim to simplify tax preparation and reduce the risk of errors.
Users remain responsible for reviewing and verifying their information before submitting any tax reports.
Our goal is that 100 % of the tax you owe is paid — the whole sum, not most of it. The app follows your tax residency and calculates the full amount. Nothing is paid before it has been checked and you approve it.
