From a question to something you can use

Small moments.
Real products.

Three different problems.
Try a small example of each.

Tollgate / Private beta

Usage has a cost.
Give it an owner.

For teams building AI products: connect usage to a customer, set pricing, and prepare monthly charges as Stripe draft invoices.

Try an illustrative $10 usage record. The example shows percentage markup only; it doesn’t connect to a provider or Stripe.

Sample usage recordIllustration
Raw model cost$10.00
Illustrative charge$14.00

Adjust the markup to see the charge change.

A customer call becomes a billable record.

WatchWise Kids / Early access

Before play.
A closer look.

For parents choosing a YouTube video: a first-pass screen of its title, channel, and thumbnail, with reasons to look more closely.

These invented examples demonstrate an explanation, not a safety verdict. The live screener does not watch the whole video.

Before they press playInvented examples
What the sample suggests

A garden story

The title describes a clear topic and the thumbnail has few competing elements. That is a starting point for a parent’s review, not proof of what happens in the video.

An explanation, before a decision.

Hisabo / Android closed beta

A month planned.
One less thing.

For households that already plan on paper: list expenses, mark bills as paid, and carry recurring items into the next month.

Tap a sample bill to mark it paid. Move to the next month to see recurring items return. This example resets when you leave the page.
