Glasp is a browser highlighter and research library that pairs your saved reading materials with language models to write cited drafts.
What it is
Glasp is a browser extension and research assistant that connects what you read on the web, PDFs, YouTube videos, and Kindle books directly to your writing workflow. Instead of staring at a blank page, you write with models from OpenAI and Anthropic on top of passages you have already highlighted, ensuring every quote carries its source, author, URL, and date.
Key features
- Highlight text on web pages, PDFs, YouTube videos, and Kindle books with automatic source citation.
- Draft content using saved passages as direct inputs for ChatGPT or Claude.
- Query your entire saved library before starting to write new pieces.
- Export notes and highlights to Notion, Obsidian, Roam Research, or download as Markdown, CSV, and JSON.
- Turn individual highlights into shareable quote images with credited sources.
Who it's for
Glasp is built for writers, bloggers, researchers, students, and lifelong learners who want to convert their reading habits and research notes into structured drafts without losing track of their sources.
Pricing
Glasp offers a free tier with unlimited public highlights, basic YouTube summaries, PDF uploads, and monthly chat credits. Paid Pro and Unlimited tiers start at $12.50 per month when billed annually, providing private highlights, higher message limits, and advanced models.
