Reading Mode & Clipping

Reading Mode

Quickly get a clean article. Reading mode removes most distracting elements from the current webpage and allows post-editing of the article. You can edit content and manually remove distractions — satisfying custom configuration needs.

Clipping Storage

Never worry about original articles being deleted. Clipping effectively parses the current page and removes distractions. It saves not only the text but also images, organizing them according to their relative positions.

Reuse [Web] Functionality

Most importantly, it reuses [Web] functionality, making this feature integrated rather than standalone.
