Use case
Describe the tool. Keep the tool.
Track my invoices — who owes what, and flag anything overdue. That sentence is the whole build. PromptDeck turns it into a small app that keeps its rows between sessions, totals them up, and changes when you describe the change.
Why it’s for you
It remembers
Rows you enter stay between sessions — this is a tool you keep, not a one-off answer. Invoice Tracker ships built in; the Mini App Builder turns any description into a new one.
Change it by describing the change
"Add a column for client email." "Change the Acme deal to $700." Code changes rebuild the tool; edits to your saved data show a diff you approve before anything is written.
The totals do themselves
Counts, sums and averages are worked out on your own machine — no model call, no network. Tell it what to track, drop a number you don't care about, or add one like your top performer.
It leaves when you want it to
Export any table to CSV for Excel, or export the whole tool as a standalone file that opens in any browser with its data baked in — no PromptDeck needed on the other end.
