Where every figure comes from
why every answer from Fold cites its exact source, and what to do if you think a number is wrong.
Every figure Fold gives you comes from a real lookup in your own files: never from an estimate or an assumption. Along with the answer, Fold tells you which file, which sheet, and which row it came from, so you can check it at a glance.
Why it works this way
An assistant that gives you a number without saying where it came from forces you to trust it blindly. Fold does the opposite on purpose: it shows you the source so trust is earned by checking, not by promising.
What happens when the data isn't there
If a question has no answer in the files Fold has read, it says so explicitly instead of filling the gap with something close enough. A clear "it's not there" beats a made-up number that looks right.
What happens when there's more than one matching row
When two or more rows could answer your question, Fold doesn't pick between them or add them up on its own: it shows you all of them, with their source, so you decide which one applies.
Untitled columns
Some files have columns with no recognizable name. Fold doesn't invent a name for them: it shows you the raw value and tells you it doesn't know what that column represents.
Hidden rows
If your spreadsheet has hidden rows (for example, an older record someone hid but never deleted), Fold still counts them and tells you how many of the rows it looked at were hidden, so you can factor that in.
How the response levels work
Behind every question, Fold first tries direct, deterministic rules; if the question needs to understand free-form language, it moves up to an AI level. Before handing you any AI-assisted answer, Fold checks that every number in the final text was actually present in what the search returned from your data. If a number fails that check (for example, because the AI tried to do its own subtraction), that answer is discarded and either retried more carefully or you're given the raw data instead.
If you think a figure is wrong
First check the reference (file, sheet, row) Fold gave you against the original: most of the time the number is correct but the file had something unexpected (a hidden row, an untitled column, an older version not yet updated). If it still doesn't add up after checking, open a support ticket from Support (see "What to do if something breaks"): a person reviews it.
