Undernote

Capture highlights, screenshots, and notes in one elegant reading workspace.

Undernote helps you save online reading without losing context. Instead of saving only plain text, Undernote lets you capture selected text, attach a screenshot from the page, and add your own note in a single highlight. This makes it easier to keep useful information organized, understandable, and ready to revisit later. Use Undernote to turn browsing into structured knowledge for study, research, analysis, and content work. What you can do with Undernote: - Save selected text from any webpage - Attach a screenshot from the visible browser area - Add your own note or interpretation - Save highlights even when no text is selected - Organize highlights into blocks by topic, project, course, or client - Edit blocks and highlights later - Export notes by block in Markdown or PDF - Optionally include screenshots in PDF exports - Use the extension in English or Portuguese - Choose light mode or dark mode
