InkStays by Dankore Software

InkStays lets you draw directly on any webpage and keep your notes there until you remove them.
Use it to mark up pages, highlight ideas, leave quick text notes, and revisit them later.

• Draw, highlight, erase, and add text on top of pages
• Notes are saved per page URL and come back after refresh/reopen
• Undo/redo, clear page, and hide/show overlay controls
• Lightweight floating toolbar with keyboard-friendly controls
• Works great for research, QA reviews, studying, and visual planning

InkStays is designed to stay minimal: fast to open, easy to use, and out of your way when you’re done.
