Thinkers Highlighter

Save the article, YouTube video, or PDF you're viewing to Thinkers and highlight it on the web.

Thinkers Highlighter turns any page into a saved, searchable part of your reading library — no copy-pasting, no separate app to open. SAVE ANYTHING, INSTANTLY Click the toolbar icon (or press Alt+Shift+S) to save the article, YouTube video, or PDF you're currently viewing straight to your Thinkers account. The extension automatically detects the content type, so you never have to tell it what kind of page you're on. HIGHLIGHT AS YOU READ Once a page is saved, a slim bar appears at the top of the article. Turn on live highlighting and every selection you make is instantly marked on the page and saved to your Thinkers library — no extra clicks per highlight. Add tags or a quick note right from that same bar. SAVE A QUOTE FIRST Prefer to grab a passage before saving the whole page? Select any text, right-click, and choose "Save & Highlight to Thinkers" — it saves the page and the highlight in one step. PICKS UP WHERE YOU LEFT OFF Revisit a page you've already saved, and Thinkers Highlighter recognizes it automatically: your existing highlights reappear right where you left them, and the overlay bar comes back in its saved state. Anchoring is text-based, so it survives minor page changes. UNDO WITHOUT FRICTION Saved by mistake? A toast with an Undo button appears immediately after every save. Made a highlight you didn't mean to? Click it to open a delete confirmation — nothing disappears until you confirm. WHY THE BROAD PERMISSIONS Thinkers Highlighter needs to read and mark up whatever page you're on, because you decide in the moment which article, video, or PDF is worth keeping — there's no fixed list of supported sites. All highlight and save data is sent only to your own Thinkers account; nothing is shared with third parties. GETTING STARTED 1. Install the extension. 2. Open the extension options and sign in with your Thinkers account. 3. Browse normally — click the icon or press Alt+Shift+S on anything worth keeping. Thinkers is a calm reading workspace: save articles, PDFs, and videos, read them without distraction, and turn your highlights and notes into a library of ideas you actually keep.
