For licensed accountants
AI is computing the world's tax returns. Who checks the rules it follows?
You do. Put your name on the tax rules AI follows in your country — and become the authority it defers to.

AICPAHow it works for accountants
You don't need to be technical. You just need to know accounting.
Get verified
Sign up with your credentials — CPA, EA, ACCA, Chartered Accountant, or equivalent. We confirm you're a licensed practitioner. Real names, real credentials.
Verify your country
Download your country's workbook, confirm the rates, thresholds, and law references in Excel, and upload it back. Your name and credentials go on every rule you verify.
Earn from reviews
When AI produces a tax worksheet, it tells users to get it reviewed. That review comes to you — the verified accountant for that jurisdiction. You set your own rates.
Know what you're putting your name on
Every rule is sourced and labelled
Every rule cites its source and carries a verification status — research-verified drafts versus accountant-verified rules confirmed by a named licensed practitioner. Browse the catalog and see exactly who stands behind each one. The framework is open source under AGPL-3.0; sign in or connect your AI to load the full packaged rules.
The vision
An accountant in every jurisdiction
The more jurisdictions we cover, the more authority we carry — with AI companies, with regulators, with the public. This isn't competition. It's collaboration. Every accountant who joins strengthens the network for everyone.
The rules cover 1000 tax, bookkeeping, and compliance tasks across 134 countries — starting with tax, expanding fast. Pick yours before someone else does.
For the self-employed & small businesses
Connect it once, and your AI stops guessing.
For sole traders, freelancers, and small businesses doing their own returns and VAT. Paste one connector into the AI you already use. From then on it loads the rules for your country — labelled by who verified them — shows its work, and hands you to a real accountant the moment it matters, instead of bluffing through your return.
