# Free tools

Alongside the product, hiy.ai keeps a small set of free utilities at [/tools](/tools). No signup, no cost — they exist because they're useful on their own, and because they show the shape of the problem twins solve.

## Repeat questions time calculator

[/tools/repeat-questions-calculator](/tools/repeat-questions-calculator)

Enter how many questions you answer a week, how long an answer takes, and (optionally) your hourly value. It shows the hours per month and cost per year — with the math visible, honestly rounded.

Everything runs in your browser. Nothing you type is sent anywhere.

## What will your audience ask you?

[/tools/audience-questions](/tools/audience-questions)

Paste the URL of a page you've written — an about page, a post, your site. We fetch it once (public pages only, through the same guarded fetcher the product uses), read up to the first ~8,000 characters, and list up to 10 questions its readers are likely to ask. Each one is marked:

- **Covered on this page** — a reader could find the answer in the page's own text.
- **Not covered** — the dashed treatment: the question would land in your inbox instead.

**Note:** The judgment comes only from the text of that one page, so treat the result as a draft, not a verdict. Limits: **5 checks per day**, and we keep nothing from the pages we read.

## How they relate to twins

Both tools stop where a twin starts: a twin answers the covered questions for you, with citations to your own material, and queues the uncovered ones so you answer each only once.
