The ten assistants are not identical copies with different interfaces — each one is built on a completely different knowledge base and deliberately restricted to it.
The eight tax and legislation assistants (Jordan, Saudi Arabia, UAE, Bahrain, Iraq, Kuwait, Oman, Qatar) are built specifically on that country's own laws and regulations, and only that country's. The Jordanian tax assistant, for example, will not confidently answer a Saudi tax question — it will clarify that this is outside its scope and suggest the right assistant instead of guessing.
The two accounting assistants (private sector under IFRS and ISA auditing standards, public sector under IPSAS) are built on international accounting and auditing standards rather than a specific country's laws, so they're useful to any user regardless of their country, as long as the question falls within those two scopes specifically.
This deliberate specialization is exactly why each assistant is accurate within its own scope — see the "Choosing the Right Assistant for Your Needs" article in the Getting Started section if you need help deciding which one fits your situation.
