Glasp

Glasp lets you highlight text on web pages and videos, and then collects everything in one place. Its YouTube summary extension produces a transcript and a short summary beside the video. Your highlights can be organized, shared with others and revisited later, and the community feature shows what other readers are saving. AI tools help summarize pages and generate a digest from your notes. Glasp is free to use, with an optional paid tier for extras. It is a good fit for readers and learners who want to remember what they read.
