ChatMARK

Stop scrolling through endless ChatGPT threads. Bookmark any answer and jump back in one click.
Detailed Description :
Ever lost a great answer in a long ChatGPT conversation?
ChatMARK lets you bookmark any part of a ChatGPT thread — just select the text and hit MARK. A color-coded tab appears
on the right rail, and one click takes you right back with the text highlighted.
No more endless scrolling. No more copy-pasting to notes. Just mark it and move on.
What you get:
• Select text → hit MARK → bookmark saved
• 10 colors to choose from with a color picker
• One-click jump with text highlighting
• Smart text matching — finds your bookmark even after page changes
• Drag-and-drop reorder
• Pin to keep saved text visible on the rail
• Inline label editing
• Search across bookmarks on the current page
• Adjustable rail opacity
• Full undo/redo (up to 10 steps)
100% private:
All data stays on your device. No servers, no tracking, no accounts. Only the "storage" permission — nothing else.
