Before you can accept a view, four checks pass.
- Every sentence cites a source.
- Every figure is found in what it cites.
- The dates agree.
- Nothing is left out: every change has its cause.
Then it’s yours to accept. Until you do, the view you had stays as it was.
Illustrative example: Kestrel Instruments is not a real company. The checks are the ones the app runs.

Why investors
choose London5.
Five questions careful investors ask about an AI assistant, and London5’s answer to each.
Where does my research live?
On your computer.
Conversations, research, simulations and watches are stored locally. Prices and news come in from London5 Finance.
Can I check what it tells me?
Every sentence, back to its source.
A view can’t be accepted until every sentence cites its source and every figure is found in what it cites.
Will it trade for me?
Not without you.
Ideas run on paper first. Anything that needs your permission waits for your approval.
What does each question cost me?
Nothing extra, on your own model.
A local model runs on your computer’s chip. A cloud model, if you connect one, bills you at its own prices.
Is this investment advice?
No. It’s research. The call is yours.
