On every page

Read it where you find it.

The web app at app.omphalis.ai is the home for everything you keep. The extension brings the same clean reading view, section map, inline explanations, and listen-along to any page you land on.

The same clean reading view, with the section map, on the page you already opened.

Clean reading on any page

The same calm, readable view the web app gives you, on the page you already opened. No clutter, no pop-ups competing for the text.

The section map in place

Strata shows the shape of the piece, where the argument turns and where the evidence thins, without leaving the page.

Inline explanations

Passive marks on the hard parts: a source, a definition, a short expansion, revealed as you pause.

Listen along

Hand any page to the standard voices and listen while the words follow along.

Keep it in place

Structure it and mark it where you found it. The page becomes a piece you keep, already mapped, without sending it anywhere first.

Every kind of page

Articles, posts, long reads, documentation. The extension works across what you actually read on the web.
