Wind is a consumer wallet for AI apps. Users load one balance and spend it across every app they connect, so you can charge four cents for a background removal and still make money. It sits next to your Pro plan, not instead of it.

  • ✓Sell usage beyond a free allowance without building billing
  • ✓Keep your subscription tier for the users who want it
  • ✓Users who already hold a balance convert in one tap

FAQ

For developers

What does Wind actually do?

Your users load a prepaid balance once. You charge them per action from it. The balance works across every app that accepts Wind, so it may already be funded before they reach you.

Where does it appear in my product?

Two places you already have. The rate limit, where a free user hits the wall and won't buy Pro. And the cancel button, where a subscriber is leaving. Both currently lead to zero.

Will this cannibalise my subscription?

You control that. You set when Wind appears, and you set a monthly usage cap below your Pro price so the wallet can never be the cheaper path for a heavy user. Most people who take usage pricing weren't going to subscribe, but the cap means you don't have to take that on faith.

Why can't I just add credits with Stripe?

You can. Three things it doesn't solve. Your credits ask the user to prefund your app specifically, which is the same commitment decision they just declined. Whatever they don't spend is stranded with you. And you inherit fraud, chargebacks, refunds, tax and balance accounting. A Wind balance is already funded from somewhere else, so spending at your app costs the user nothing new.

Why can't I just charge 50 cents myself?

Card fees. At 2.9% plus 30 cents, a 50-cent charge loses 63% to processing and anything under 31 cents costs more than it collects. That forces you to bundle up to $5 or more, and the bundle is the commitment your user already refused.

What does it cost me?

Nothing upfront, no minimum, nothing if nobody spends. We take a cut of what clears. The real cost is engineering time, and it's a payment flow to build and test like any other.

Do I set the price?

Yes. Per action, at whatever fits your product. We don't set it and we don't meter your tokens.

What about chargebacks and fraud?

They happen at the load, not at your charges, so they sit with us rather than with you. That's a meaningful part of what you're buying.

Do my users need a Wind account?

Yes, and that's the honest friction. It's one signup and one card entry, after which every future purchase across every Wind app is a click.

What if none of my users have a balance?

Right now, most won't. That's why we're launching with a cluster of apps serving the same person rather than signing apps one at a time.

For users

What is Wind?

A balance you load once and spend across AI apps. Pay for what you actually use instead of a monthly subscription.

Why load money before choosing an app?

Because the same balance works everywhere Wind is accepted. If you only ever use one app, a subscription may suit you better. The wallet is for people using several tools occasionally.

What does it cost me?

Nothing. Wind is free to use. Apps pay us, not you.

Do I have to load a lot?

There's a minimum because card fees make tiny loads uneconomical for us too. Whatever you load stays yours.

Does my balance expire?

No.

Can I get a refund?

Yes, on unspent balance.

Do the apps see my card?

No. You enter it once with Wind and never again at an individual app.

Is this cheaper than subscribing?

Depends on usage. If you use something daily, a subscription is probably better value. If you use it a few times a month, paying per use is almost always cheaper.

One balance across every AI app you use.

Load once. Spend anywhere Wind is connected. Pay for what you actually use.
