Glossium Join the Waitlist

Coming SoonPublic beta for Mac

A browser that reads the web with you.

Calm Spaces for your tabs, and Gloss beside every page.

Be first to try it. Join the waitlist.

We use your email only to tell you when Glossium is ready, and you can ask to be removed at glossium@arhmn.sh.

Mac first; more platforms to come, inshallah.

An illustration of a Glossium window: a sidebar of tabs in a Space called Research, a page of notes beside it, and the command bar open over both.
Glossium’s window: your tabs in a sidebar, a page beside them, and the command bar over both. A drawing, until the film is ready.

Bring your browsing over.

Bring your bookmarks and history from the browser you use now. The welcome sheet brings them over, and nothing is added until you confirm.

A Space for every part of your life.

Work, home and everything in between each get a Space of their own, with its own colour, Pinned sites and tabs. Only what belongs to what you’re doing is in front of you, and the rest waits where you left it.

Coming Soon A separate sign-in for each Space, so your work and personal email can stay open side by side.

Try a colour.

One bar for everything.

Every tab you have open, in any Space, Glossium’s own actions and the web are all in one place, so a few letters find what you need instead of a hunt through rows of tabs.

Peek at links.

Look at a link without losing your place or piling up tabs. Its page opens over the one you’re reading and goes away when you’re done, unless you decide to keep it.

Two pages, one window.

Compare two pages, take notes beside an article or follow a guide while you work, with both in view instead of switching back and forth.

Tabs tidy themselves.

Tabs you’ve stopped using move to the Archive after a day and stay there for 90 days, so the sidebar stays short and nothing is lost.

The gist before the click.

Before you open a link, you can know what’s behind it: the article’s picture, title and reading time, and a summary in a few lines when you want one, made on your Mac whenever it can be.

A calmer way to read.

Coming Soon A reading mode of Glossium’s own: any article in one clean column, with everything but the words set aside.

Ask any page.

Gloss reads the page with you: a summary, the key points linked to the passages they come from, and answers to your questions. It uses your own Claude key and sends a page only when you ask.

Hide everything but the page.

The sidebar slides away so the page has your full focus: no bookmarks, no address bar, nothing else. It’s good for demos too, when you share your screen.

And more on the way.

These are planned for Mac. None of them is in the beta, and the order may change.

Privacy, in brief.

  • No account. Glossium doesn’t sign you in. You open it and start browsing.
  • Your pages stay yours. Gloss sends a page’s text to the provider whose key you added, only when you ask. Apple’s on-device model sends nothing.
  • One regular question. Every few hours Glossium asks its update server whether a newer version exists. Like any web request, it carries your IP address.
  • Nothing about your pages. Crash reports carry no web addresses, page titles or page content, and nothing about how you use Glossium is sent unless you switch on anonymous usage counts.
