Feature Comparison
Bizora Inc.
Instant, Citation-Backed AI Tax Research
This core feature acts as an AI research assistant that answers complex federal, state, and cross-border tax questions in seconds. Unlike generic tools, every answer is directly sourced from current primary authorities like the IRC, Treasury Regulations, IRS rulings, and case law. For deep analysis, the "Deep Research" mode deconstructs questions, reviews multiple authorities independently, and synthesizes a complete memo with step-by-step citations, transforming hours of manual work into minutes.
Step-by-Step Transaction Playbook for M&A
Bizora provides structured, automated workflows specifically designed for complex transactions like mergers, acquisitions, and restructurings.

This ensures nothing is missed, keeps the entire team aligned, and adapts to various deal specifics, including entity types, jurisdictions, and cross-border considerations.
Automated Document Parsing in The Vault
The Vault feature allows users to drag and drop any client file—such as tax returns, K-1s, contracts, or financial statements (PDF, Word, Excel, etc.)—for instant analysis.

Users can summarize documents, flag discrepancies, or attach files directly to research queries, grounding every AI answer in the specific context of the client's actual documents.
Integrated Drafting with Canvas
