What Blue J is
Blue J is a web-based generative AI application for researching tax law through a natural-language interface. It returns answers with relevant source documents, verifiable sources, in-line citations, and source lists. Users can upload files to analyze alongside Blue J’s authoritative tax content, then download answers as PDF or DOCX or generate memos and emails. Blue J says its primary tax sources are current and updated daily, drawing mainly on primary resources and Tax Notes news and commentary. The Individual Plan costs $1,498 a year per user and includes US federal and SALT tax coverage, unlimited questions, drafting, file uploads, citations, and source lists. A seven-day trial requires no credit card. Blue J uses language-model technology from OpenAI and Google and says customer data is not used to train generative AI models. Data is stored in AWS us-east-1 in North Virginia; other jurisdictions and on-premise deployment are not offered. Optional files are deleted daily after 24 hours.
