Early access Onboarding Claude users first

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.

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.

The feed

Every agent. Every dollar. One view.

How it works

Connect. Set limits. Approve.

01

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.

02

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.

03

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.

04

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.
