About

Glasp is a free browser-based highlighting tool that addresses a common problem for readers: useful passages found online are easy to lose and hard to revisit. With Glasp, a person can highlight text directly on web pages and PDFs, attach notes to those highlights, and keep everything in a single personal archive that can be tagged, searched, and exported.

The tool works through a browser extension, so highlighting happens in place while reading rather than requiring copy-and-paste into a separate app. Glasp also has a social dimension: highlights are public by default, so users can follow other readers, discover what passages resonated with people whose judgment they trust, and learn from shared notes. The project is developed by an independent team and is offered at no cost to users.

Key Features

Web and PDF highlighting: Users can select text on articles and PDF files and highlight it in their choice of color without leaving the page.

Notes and tags: Each highlight can carry an attached note, and highlights can be tagged so a growing collection stays organized and searchable.

Highlight export: Saved highlights and notes can be exported in formats such as CSV, plain text, or Markdown, which makes it straightforward to move quotes into note-taking apps like Notion, Obsidian, or Roam Research.

Social discovery: Because highlights are shared publicly, users can follow other readers, view their notes on the same articles, and find new reading material through people rather than algorithms alone.

YouTube transcript summaries: Glasp can work with YouTube transcripts, letting users highlight and summarize video content alongside written articles.

AI writing feed: The service lets users build a feed from their own highlights that can serve as source material for writing, and it offers a way to generate a chat interface trained on one's highlights and notes.

Quoteshots: Users can turn a saved quote into a shareable image, which is handy for posting insights to social media.

Pricing & Fees

Pricing: Not publicly listed on the pages we reviewed; check the official site for current plans. Glasp is widely offered as a free tool.
Platform availability: Glasp runs as a browser extension, available for major Chromium-based browsers; the official site lists current supported browsers.
Free to use: No payment is required to highlight, take notes, and share, which distinguishes it from many paid note-taking products.
Export flexibility: Because highlights can be exported in structured formats, Glasp can serve as a capture layer feeding other knowledge-management tools rather than replacing them.

Who It's For

Glasp is built for people who read a lot online and want to retain what they read: students collecting sources for papers, researchers tracking literature, writers gathering quotes and ideas, and general readers who want a permanent record of passages that mattered. It also suits bloggers and newsletter authors who want to share what they are reading with an audience, since public highlights function as a running, low-effort reading list. Anyone who already keeps notes in Notion, Obsidian, or a similar app can use Glasp as the capture step in a larger workflow.
