Bizora

Bizora sits in the fast-growing pack of AI tax research tools chasing Thomson Reuters and Bluej, with a distinctive twist: it now sells human review hours alongside the software.

What it does well. The platform is trained on primary source material, and the vendor says every answer carries citations to the IRC, regulations and rulings, which is the right design for professional use. Pricing is transparent and low, all-state coverage is included, and the MCP integration means firms already working in Claude or Copilot can pull Bizora research into their own workflows. The new Advisory Group, where credentialed CPAs and EAs sign off on positions, is a sensible answer to the obvious question of who stands behind an AI answer.

Where it falls short. Accuracy claims are the vendor's own and there is no published benchmark against established research platforms. The Advisory Group is explicitly not an accounting firm and is scoped by hours, so firms should read the engagement terms carefully. It is US-focused, so UK practitioners will find little here.

Best for. US tax professionals, from solo EAs to mid-sized firms, who want cheap, citation-backed research and an optional second reviewer for riskier positions.

Verdict. A credible, keenly priced research assistant worth trialling, provided you treat its answers as a starting point and not a sign-off.
