YourBrain2 is built for people who want their notes, their memory and their paperwork on their own computer, not in someone else’s cloud.
Everyone has the same pile: bills, receipts, letters from the tax office, a payslip, a photo of a parking ticket. Sorting it is boring, and the tools that promise to do it want your documents in their cloud.
We wanted the opposite: an app that keeps everything as plain files on your own computer, lets an AI of your choice read them with your own key, and then checks the AI with fixed rules, because a number that is not in the document must never land in your totals. Anything uncertain is marked “Please check” instead of guessed.
That is the whole idea. The AI prepares. You decide. Your accountant still checks the figures.
Plain Markdown and PDF in your own folder. Nothing is uploaded to us. If a plan ends, everything stays readable.
Fixed rules check every amount, currency and date against the document. Unclear goes to "Please check", never into a total.
The app prepares and sorts. You confirm. Your accountant checks. Nothing is filed or paid for you.
You choose Claude, OpenAI, Gemini or DeepSeek and pay the provider directly. We never see your documents.
Four plans, one price each, cancel anytime. The first payment can be refunded within 14 days.
Every country rule was tested on real documents: Swiss, German, American, Turkish and Pakistani.
