Why IntellixCore
Not a generic AI chatbot. A specialised agent built for qualified tax professionals — whether you advise clients in a practice or manage tax obligations within an accounting department.
Draws on thousands of UK tax tribunal cases, Court of Appeal and Supreme Court decisions — surfacing relevant precedent for both advisory practices and in-house teams.
References published HMRC manuals, practice notes, and statutory instruments to ground every answer in current authority — whether for client advice or internal sign-off.
Outputs are formatted as professional advisory drafts — ready for your team's QA review before issuing to clients or circulating internally.
Every output is explicitly flagged for qualified adviser review. The agent supports your professional judgement; it never replaces it.
Complex research that previously took a senior associate two days can be scoped, researched, and drafted in under 15 minutes — in a firm or an in-house team.
Built to the governance standards that regulated environments require — auditability, traceability, and defensible outputs for both PS firms and corporate tax departments.

Trust & Confidentiality
Whether you are a PS firm advising clients or an in-house tax team managing corporate positions, every architectural decision protects your confidentiality — and your budget.
All submitted queries and generated outputs are permanently deleted after 60 days. Your conversation history sidebar remains accessible for the full 60-day window. Automatic deletion after 60 days or delete anytime from the sidebar.
IntellixCore does not use client data, queries, or outputs to train or fine-tune any AI model. Firm strategies and in-house tax positions stay entirely yours.
Architectural guardrails prevent data leakage between sessions and users. Each query is isolated — your firm's work and your clients' data are never commingled.
Azure-native infrastructure with UK data residency. Every session is encrypted in transit and at rest. ISO 27001-aligned controls for regulated environments.
Firms and in-house teams spend thousands annually on external legal databases. IntellixCore consolidates UK tax case law, HMRC guidance, and legislation into one platform — at a fraction of the cost.
