Reader, Annotations, and Discussions

The Reader keeps source text, highlights, discussions, and distilled notes in one reading workspace. You can return to the exact source location behind a judgment instead of keeping detached notes.

Reading View

The Reader includes the body text, highlight marks, highlight connections, and a sidebar. The floating toolbar offers common actions like table of contents, search, and highlight navigation, plus persistent chat to question assistants about the current item. Web articles also support bilingual translation, with feedback on the affected paragraphs as the translation is applied back to the body so you can confirm which text changed.

• Table of contents: toggle the TOC to expand the chapter list. It highlights and focuses the active section so you can inspect surrounding structure from your current position.
• Search body: search keywords in the current item and jump to the matching position.
• Highlight navigation: jump quickly between the previous and next highlight without scrolling through the body.

You can adjust the layout:

• Web articles and ebooks: font size and article width.
• PDF: use PDF zoom to change page size, which corresponds to font size and page width for the other source types.

Theme and reader paper are switched from the theme entry on the home page (light, dark, dusk indigo, and other themes plus reader paper), not from inside the Reader. Paper colors affect web articles, ebooks, and PDF reading surfaces. In dark mode, PDFs keep their original page colors.

Create a Highlight

1. Select text in the Reader.
2. Draggable handles appear at both ends of the selection — drag them to extend or shrink the range without reselecting (supported in web articles, ebooks, and PDFs).
3. Press the default A shortcut, or use the selection action button.
4. Write a thought, question, or note.

The highlight is shown in your personal color and anchored to the source text. Highlight creation, copying a selection, and similar actions can be paired with sound feedback (toggle sound and volume in Settings > General).

Discussion

Every highlight has its own discussion thread. Open the discussion from an annotation card to add thoughts, reply to existing notes, or mention an AI assistant with @assistant name. Assistant replies are generated from article context, the selected passage, and the existing discussion.

Discussions support pinning important notes, deleting your own notes, and switching between split and left-aligned layouts.

Distilled Notes

When a highlight has grown into a judgment, framework, question, or action reminder worth keeping, open the distillation window and turn scattered comments into a concise note, then validate, preview, and apply review assistants’ structured feedback item by item. See “Distilled Notes and Review”.
