Your questions, answered
Blue J leverages the latest large language models and our vast database of tax content to deliver industry leading quality answers to challenging tax questions in seconds. Answers are backed by relevant source documents empowering tax experts to perform exceptional analysis faster than ever.
Blue J’s curated database consists mainly of UK Public General Acts, Statutory Instruments, HMRC Manuals, VAT Notices, UK Tax Treaties, as well as commentary from Tax Notes. Together, these primary and secondary resources ensure both breadth and quality in the answers we provide.
When Blue J responds with “I don't know," it means it is unable to accurately respond to your query at this time. There could be a few reasons why:
- Blue J does not have the source material to respond accurately
- Blue J could not interpret the prompt to produce the correct context for an answer
This response demonstrates the strength and reliability of our platform, and how we are working to eliminate "hallucinations” - inaccurate or fabricated answers provided by the model.
Blue J does not read, share, or learn from any information input by our users without explicit permission. Customer questions are stored in a secure, encrypted database, only accessible to select individuals who need access to maintain the database. We work with an independent auditor to maintain a SOC 2 Type 2 report on an annual basis, which objectively certifies our controls to ensure the continuous security of our customers' data.
