C9 AIIRS & CRA research
US and Canadian tax questions, answered from guidance you upload.
Set each workspace to the US or Canada, a state or province, and a tax year. Upload IRS or CRA guides to your Library, and when an answer uses them you'll see the page it came from.
Shared Library
Upload a guide or save a public web page once, and every workspace can use it.
Approved websites
Admins choose which websites can be saved to the Library.
No made-up references
For a general question you'll get a general answer without fake citations. A citation only appears when one of your documents was actually used. C9 AI doesn't search IRS or CRA websites on its own — it uses what you add.
- IRS publications and form instructions
- CRA guides and slip instructions
- State and provincial guidance you upload
- A warning when a cited page only loosely matches
