Parail is a web browser with two panes. Keep a video playing on top while you read a map or an article below — even with sound in both. On iPhone Duo, pages extend all the way under the strip on the right edge.

Two pages at onceSomething the built-in browser can't do: two web pages open side by side

FAQ

Questions

Is it a subscription?

No. Parail is free to download and use. Parail Pro is a one-time purchase that unlocks extra features, and Family Sharing is supported.

Which devices does it work on?

iPhone and iPad with iOS 27 or later, including the foldable iPhone Duo. On iPhone the two pages sit top and bottom; on iPad and an open iPhone Duo they can sit side by side.

Can I play sound from both pages at once?

Yes. Videos with sound can play in both panes at the same time. You can turn this off in Settings > Page.

Can I stay signed in to two accounts on the same site?

Yes, with profiles (Pro). Each profile keeps its own cookies and logins, so you can open the same site with different accounts side by side.

How does the AI panel work?

Parail shows the official ChatGPT, Claude or Gemini website next to your page. You sign in with your own account. Parail does not provide an AI service and never sees your login.

Do you collect my browsing data?

No. There is no account, no developer server, and no analytics or ad SDKs. History and bookmarks stay on your device, or in your own iCloud if you turn on sync.

Which languages are supported?

English and Japanese. Other languages show English.
