Every passage you highlighted, with its source attached, sitting next to the draft. The blank page is the problem — not the writing.

Glasp is a highlighter that turns research into a drafting surface. Every passage you keep is stored with its source, author, URL and date, so when you sit down to write, the material is already collected and every quote is already cited. You can draft on top of it with ChatGPT or Claude, export to Notion or Obsidian, and publish with the highlights attached. Free monthly quota, no credit card.
Highlight the passages you might use — articles, PDFs, YouTube videos, Kindle books — and tag them as you go.
Search or filter your library by tag, source or author until the material for this piece is in one place.
Write with ChatGPT or Claude on top of your own passages, and keep the link back to each source so a citation is one click away.
Highlight while you read and the source, author, URL and date come with the passage. The half hour you normally spend finding a quote again is a hidden tax on every piece; this removes it.
Write with ChatGPT or Claude using your passages as the input, not the open web. What comes back is grounded in sources you have read, which is the difference between editing and fact-checking.
Ask a question across everything you have ever saved and get an answer with its sources, so you know what you already have before deciding what to write.
A Glasp post carries the highlights it grew from, so a reader can follow the argument back to its evidence. Quoteshots turn a single passage into a shareable image with the source credited.
Highlight anything on the web or in a PDF and keep it with a note.
Bring highlights over from Kindle, Pocket, Medium, Instapaper and Readwise.

researchers, students, and lifelong learners highlight with Glasp.
“I love Glasp! I use it every time I read online articles. Highlighting with Glasp enforces me to actually read rather than scan through an article. I retain so much more info and can easily revisit my previously read articles to recall details and notes I've made.”
“I've researched every highlighting tool from Liner and Hypothesis to Instapaper and Pocket, and Glasp is the best hands-down. First, it creates a whole category of its own with social highlighting. This is important because it helps learners get recognized for finding amazing highlights, and it helps them connect with others who are learning the same thing at the same time. Also, it has the best highlighting workflow. While reading an article, you can select text in order to highlight and annotate without having to go to a different page. Furthermore, all of your highlights for a specific article appear on a right sidebar as you're reading, and they're easy to copy and paste into another note-taking app.”
“I used Instapaper but ended up hating it and stopped. There just wasn't a tool for me to continue using until Glasp. I was hooked immediately for the ease of use (highlight directly on the article web page), organized feed, and learning from others' highlights and notes. It makes sticking to learning something so easy and you can no longer find any excuses. Highly recommended to anyone who loves reading awesome articles or want to start forming such habit.”
It removes the worst part of writing from research: finding the quote again. Every passage you highlight is stored with its source, author, URL and date, so when you draft you are working from material you already collected rather than re-Googling something you half-remember.
The input. A general model writes from the open web, which is why it produces confident text you then have to fact-check. Glasp drafts on top of passages you chose, from sources you read, and keeps the link back to each one — so the citation is already there.
