Glasp Description:

Glasp is an AI-driven social highlighter and knowledge management tool designed for learners, researchers, writers, and curious minds who consume content across the web, PDFs, and video. The platform offers a seamless way to capture, organize, recall, and share insights from what you read and watch — turning passive consumption into an active, networked learning process.

At its core, Glasp enables you to highlight and annotate text on web pages and in PDF documents. With a simple browser extension or mobile app, you select text and apply colored highlights or notes, and those highlights are instantly saved to your Glasp account. These highlights can be tagged, organized, and accessed later. You can also highlight parts of YouTube videos with timestamps, allowing you to annotate sections of a video and revisit them easily.

Glasp adds powerful AI capabilities: from your collection of highlights, it can generate summaries of web pages, videos, or books. You can build a personalized “AI clone” — a model trained (implicitly) on your highlights and notes — which you can query for insights, suggestions, or recall of your own learning history.

The platform supports importing highlights from Kindle, Pocket, Medium, and other sources, ensuring continuity in your knowledge archive. It also offers exporting features, so your highlights and notes (with metadata) can be sent to Notion, Obsidian, Roam Research, or as markdown, CSV, or text files.

Glasp is more than a personal highlighter: it is social. You can publish your highlights, follow others’ highlights, and see what like-minded people are reading. This social layer helps you discover insights beyond your own reading, as you browse what others find valuable.

Mobile support expanded in 2023: Glasp launched iOS highlighter capability, allowing users to mark content directly inside Safari, bringing highlighting to mobile browsing without needing to open a separate app.

The tool is offered under a freemium model: highlighting and many base features are free (with unlimited public highlights), while more advanced features (AI summaries, private mode, deeper “clone” interactions) may require a paid tier.

By combining annotation, summarization, sharing, and AI recall, Glasp turns your reading and research into a living, retrievable knowledge base. It empowers users to not just consume content, but to interact, remember, and build an intelligible digital legacy of their learning.
