Gloss

Gloss is a web reading application that lets users highlight any line of text and ask questions about it.

Gloss is a reading tool designed for articles, chapters, and PDFs. Users can open a PDF, paste text, or paste a link to read content. The application works by letting you select any specific word, sentence, or passage. You can then ask questions, and the answer lands directly in the margin while citing the text. It also keeps your highlights synced across every device when you sign in. The platform provides sample texts from authors like Huxley, Schopenhauer, and Thoreau for new users to try.
