Blue J
Blue J is a generative AI tax research tool that answers tax questions conversationally and links each answer to the sources behind it, drawing on primary tax authority plus Tax Notes and IBFD content. It is sold to accounting and tax firms from sole practitioners up to national firms, and can turn a research thread into a draft memo or client email.
What the AI does
- Conversational tax research answers with cited passages that can be opened inside the platform
- Follow-up questions to test an answer against changed facts, exceptions or a narrower jurisdiction
- Converts a research thread into a draft technical memo or plain-language client email, exportable to Word or PDF
- Reformats research into other outputs such as checklists, FAQs and presentation outlines
