Frequently asked questions

How to use Hades.

A few answers to help you explore Hades.

Back to the collection

How do I find a tool?

Choose a category, such as Learning & Knowledge or Work & Careers, then browse its sections. You can also search by a tool’s name or what you want to do. Choose Everything to search across the whole collection.

What happens when I select a website?

A preview opens with a short description and the categories and sections it belongs to. Select the Visit link to open the original website in a new tab. Close the preview with its close button or the Escape key.

How does “Find something unexpected” work?

The shuffle button picks a random website and opens its preview. Leave the dropdown on Everything or choose a category to narrow the surprise. This choice is separate from your search and browsing filters. Close the preview and press the button again for another pick.

What is an Editor’s pick?

A website Sora uses or recommends. Look for the gold star on its icon; its preview may say why it was picked. A pick is a personal recommendation, not a guarantee, so check each site’s own terms. See them all under Editor’s picks.

Why do some tools appear in more than one category?

Some websites are useful for more than one thing. They can appear in several categories, but each view lists a website only once. Its preview shows all the places it belongs.

Is Hades free, and do I need an account?

You can browse Hades without paying or creating an account. The websites in the collection set their own prices and access requirements; some are free, and others offer paid plans.

How can I suggest a tool?

Use Suggest a tool (opens a form in a new tab) to send its link and any helpful details. Suggestions are reviewed before they join the collection, so submitting a link does not publish it immediately.
