Question 1

How do I save an article online to read later?

Accepted Answer

Use a read later app: install its browser extension, click save on any article, and read it later in a clean view without ads. Lumen does this for free, keeps your place, and builds a short daily reading plan so saved articles actually get read.

Question 2

What is a read later app?

Accepted Answer

A read later app saves web articles as clean, readable copies in one inbox, so you can read them when you have time instead of keeping dozens of tabs open. Good ones add highlighting, notes, progress tracking and export to your notes app.

Question 3

How do I highlight text on a website and save it?

Accepted Answer

Install a web highlighter extension such as Lumen, select text on any page, and pick a colour from the toolbar that appears. The highlight is saved with a link back to the exact passage and reappears when you return to the page.

Question 4

Why can't I copy text while highlighting, and how do I fix it?

Accepted Answer

Highlighters that work as a mode (such as Obsidian Web Clipper's highlighter) capture every selection, so you cannot copy until you switch the mode off. Use a highlighter that shows a toolbar next to the selection instead; Lumen does this, so Ctrl+C keeps working.

Question 5

How do I send web highlights to Obsidian?

Accepted Answer

Install Obsidian's Local REST API plugin, add it as an Obsidian destination in Lumen with the note path, and point a collection at it. Every new highlight you make in that collection is appended to the note once, in Obsidian's ==highlight== syntax with a link back to the source.

Question 6

How do I append highlights to an existing Obsidian note instead of creating a new one?

Accepted Answer

Clippers create a new note unless a template says otherwise. In Obsidian Web Clipper, set the template behaviour to append to an existing note. In Lumen, point a collection at the note and pick that collection in the extension; every new highlight is appended there automatically.

Question 7

How do I stop duplicate highlights when I clip the same page twice?

Accepted Answer

Duplicates happen because the clipper sends every highlight on the page each time. Use a tool that remembers what each note already received. Lumen keeps a delivery ledger per destination, so a highlight is written once, no matter how often you sync or clip.

Question 8

How do I save web highlights to Notion?

Accepted Answer

Create a Notion internal integration, share your target page with it, and add the page and token as a Notion destination in Lumen. Point a collection at it; new highlights are appended to the page as quote blocks with a link back to the passage.

Question 9

How do I highlight a PDF in Chrome?

Accepted Answer

Chrome's built in PDF viewer is closed to extensions, so web highlighters cannot mark PDFs there. Open the PDF in a viewer that supports annotations: a tool's own PDF viewer, Zotero, or Obsidian with the PDF++ plugin. Lumen's own PDF viewer is in progress.

Question 10

How can I use Claude or another AI agent with my reading list?

Accepted Answer

Connect the agent to Lumen's MCP server. In Lumen press Connect agent, copy the command for Claude Code (claude mcp add) or the config for Claude Desktop or Cursor, and ask things like "what did I read about evals this week, and what should I write next?"

Question 11

How do I turn my reading highlights into blog post ideas?

Accepted Answer

Collect highlights with a note on why each mattered, then look for passages from different sources that make the same point. That overlap is a post. Lumen's Spark does this automatically: it reads only your highlights and suggests titled ideas with outlines and cited sources.

Question 12

How do I build a reading habit online?

Accepted Answer

Make it small and daily: pick one article you started and one short new one, read them in a clean view, and mark them done. A streak helps if it rewards attention (notes, finishing) rather than volume. Lumen's daily reads and glow streak are built around this.
