Built by accountants, backed by peers
Accountants build the Guides. Your AI uses them.
OpenAccountants gives software and the AI you already use visible, source-cited Tax Guides instead of relying on training data alone. Named accountants build those Guides, attest to the work of their peers, and keep them current.
The four steps
An accountant builds a Guide
A named accountant turns a job they know cold into a source-cited Tax Guide, drafting it with the AI they already use. Every figure traces to its authority.
Peers attest to it
Other accountants professionally stand behind the Guide. Their names join the author's on a public record, and the Guides more accountants back are the ones AI reaches for.
It is versioned and published
Each Guide becomes structured records, machine-readable files, public diffs and current releases, credited to the people behind it.
People and AI use it
People, software and the AI you already use reach the same maintained Guides, on the website, on GitHub, or added straight to your AI.
An accountant builds a Guide → peers attest → it is versioned and published → people and AI use it
