Configure spending for AI agents.
Flute is the easy-to-use platform that allows users to control their AI agent spending. Set a budget and rules for each one, approve what matters, and see every purchase in one place.
“Nonstop both ways, and back in time for Sunday dinner.”
One-time virtual cards
Made the moment you approve. Works for that one purchase, then closes.
Be in the loop
Approve each one, or only the ones over the limit you set.
Autonomy when you want it
Flute learns what you approve, so trusted agents can buy on their own.
Every agent. Every dollar. One view.
Your agents have spent $1,284.19 of $2,350, with twenty days to go. Most of it is the Portland trip: the hotel and the rental car.
Trips is waiting on you for a $412.60 flight to Chicago. The ask expires at 14:11. Gifts tried to buy a gift card last night. Gift cards are blocked, so nothing was charged.

Connect. Set limits. Approve.
Connect your agent
Say “Connect Flute” in your assistant and give it a six-digit code. It pays with a new card each time — it never sees yours.
Set how it can spend
An allowance, the amount it asks above, the sites it can use. Gift cards, crypto and brand-new sites stay blocked.
It asks when it matters
Over the line, you see the exact purchase and the agent's reasoning. Approve with a passkey, decline, or ask for changes.
A card for one purchase
Each yes makes a card that works at one site, for one amount, and closes after one charge. Nothing standing to leak.
Get in before your agents get ambitious.
