Can we send a member of staff a birthday gift tax-free?
Usually, yes: if it isn’t cash or a cash voucher, costs £50 or less, isn’t in their contract and isn’t a reward for their work1.

Your client files stay with your AI.
Solved never sees your documents or your conversations. Your AI only asks Solved what it wants to look up.
Your files and chats stay in your AI.
Solved never receives them.
Your AI only sends searches.
It asks for the sources it needs, and nothing else.
Client details are turned down.
If a search includes a name or reference number, Solved refuses it and asks your AI to describe the facts generally.

Why not just…?
The questions we hear most often.
It helps, but your AI still reads only what it finds, one page at a time. It won’t reliably follow a section to the definition it relies on, or to the HMRC guidance that explains it, and it rarely finds the version that applied in an earlier year.
Solved gives it each section with what it cites, what cites it and every version by date, in one step.
